Expanded clay in bags or in bulk: how to calculate the volume

Expanded clay as a multifunctional material is distributed in different areas of construction. Its main advantage - a high degree of sound and heat insulation. Therefore, it is increasingly being used as a heater. Expanded clay is widely used in agriculture and manufacturing. There are several types of material and packing. How to choose and calculate the required amount, which is better: expanded clay in bags or in bulk? The answers to these questions is contained in this article.

Expanded clay in bags: features and positive quality material

Expanded clay has long been used in different spheres of production due to a number of its positive qualities. This is an easy, natural and eco-friendly material which is made of clay. He is practical to use and provides a high degree of sound insulation and heat saving in buildings. coefficient of thermal conductivity of the material is quite low - 0,1-0,18 W / m · K.

Additional benefits of expanded clay - is its relative resistance to humidity, frost and fire, as well as biopersistence. It does not form the fungus and not infest rodents. Properly chosen proportions, the quantity and compliance with stacking technology ensures reliability claydite ties and its long operating time.

The large volumes of expanded clay is used as a drain on the roads, to build the pavement and embankments in the garden. Since it is quite simple to operate. However, before you buy expanded clay in bags or in bulk, you need to properly calculate the required amount of material.

Expanded clay granules have a different shape. They are obtained from special grades of clay, has a high degree of swelling at high temperatures. Thanks to these characteristics appear pores, which provide thermal insulation properties of the material.

Produce Expanded clay loose and in bags in three types. The sand granules is up to 5 mm in diameter. Gravel has a rounded shape and a grain size up to 20 mm. Crushed - more angular material, its fraction - 20-40 mm.

The density of expanded clay and material grade

Expanded clay is lightweight, and the density of the material determines the quality and area of ​​use. It is this value affects the amount per cubic meter and therefore the weight of the expanded clay bag. This figure depends fractions: larger than granules, the lower the density of the material.

Useful advice!When you purchase it is necessary to take into account the expanded clay bulk density, which indicates the material type.

Technology of production influences the density of the material. There are four method for producing this material:

1. Dry. The simplest technique used to homogeneous classes of clay without impurities. Humidity is not more than 9%.
2. Wet.
3. Plastic. The most common method. form granules and sending into the furnace from the wet clay. raw humidity reaches 30%.
4. Powder-plastic. Similar to the previous method, but as a basis for taking dry clay, which is crushed, and then moistened and subjected to temperature influences.

It is a brand of the bulk density of expanded clay. Is designated by the letter M with a corresponding number. For example, M300 denotes that 1 cc of expanded clay weighs 251 to 300 kg. The lower the grade, the better the insulating properties. This material is best suited for the insulation of ceilings and floors.

LECA lower mark (fractions 20-40) was used as a thermal insulator in the bases and basements. It is widely used for landscaping. Material with a minimum density of use for thermal insulation of walls, facades and communications. Smallest expanded clay (with a grain size up to 10 mm) are used in the preparation keramsit pouring floors.

The specific density and specific gravity of expanded clay

expanded clay density is measured using a bulk method, and by calculating its volume weight. This characteristic indicates the true weight of sand, crushed stone or gravel - without taking into account the space in the middle of expanded clay granules. This feature is the basis of differences in bulk and true density, which is almost always different from each other. Apparent density - is a constant parameter, it can only be measured in special laboratories. Specific gravity varies depending on the grain fractions.

How heavy is the cube of expanded clay, table demonstrates:

kind of expanded clay	Fraction granules, mm	The specific weight of the material, g / cm³
Sand	0,1-5	0,55-0,6
fine gravel	6-10	0,4-0,55
coarse gravel	10-20	0,35-0,4
crushed stone	20-40	0,2-0,35

Weight of sand can be up to 600 kg per cubic meter, pea gravel - 450 kg, large - 400 kg. Cube gravel will weigh at least 350 kg. The higher density of expanded clay, the material has a greater weight. These indicators regulates the existing Standard.

The exact proportion of expanded clay difficult to determine, it is possible to establish a mean value, which is 400 kg / m³ (0.4 g / cc). At this rate affects primarily the size fraction. For example, one bag expanded clay volume fraction of 10-20 cc and weighs approximately 16.7 kg.

How much is a concrete block: what determines the price of the material

In a network of building supermarkets offer a wide range of expanded clay. This product can be purchased in bags or in bulk. In the absence of appropriate conditions for storage of the material in bulk is better to choose products in packaging.

Useful advice!Buying expanded clay, it should be noted that smaller pellets have a lower thermal conductivity, while having the highest rate of bulk density.

Packing promotes easy transport, shipping and warehousing for storage. During transportation of the material does not disintegrate, and its use will be waste-free.

Packed material cleaner and has no foreign inclusions. You must know that the cost per cubic meter of expanded clay is slightly cheaper than in bags. But if you intend to wholesale purchase of several cubes, it is more profitable to buy expanded clay in bags with delivery.

On the cost of the material, which is formed by the manufacturer, it affects the quality of raw materials, production methods, storage conditions and transport costs. Considerable importance has the production capacity and production volumes, energy, labor, and total turnover on the market.

How much is a bag of expanded clay: factors shaping the retail price

It is necessary to take into account many other factors that determine how much expanded clay in bags. The price is formed on the basis of these components:

• expanded clay fraction. The main caveat is this: the smaller the grain size, the more expensive will cost the bag. It depends on the density and weight ratios described above. It should be noted that the cost of sand is much higher than, for example, gravel or crushed stone;
• the existence and size of the pores in the material. The porosity, that is, the number of cells in the fault granules depend insulating quality of expanded clay. Accordingly, this factor directly affects the formation of prices;
• way of packing material. Paper bags in multiple layers provide good protection of the goods against dirt and moisture. In addition, in this way it is easier to carry out loading, transportation, storage and accounting of products;
• packaging. The process of distribution of the material - this is a special, separate production cycle, which requires additional labor and space. For this purpose special equipment sold in the form of dispensers, special weights and bulk hopper;
• weight expanded clay bag. The value is also affected by the number of kilograms of expanded clay in the bag. Packing 25 kg cost more bags with the same material of 50 kg;

• the total amount of the purchase. Large parties with a significant number of bags cost less. Most vendors offer price once wholesale and retail;
• payment method. Sometimes sellers make special discounts for the purchase of material for cash (or if the bank transfer is carried out through partner banks).

Price of expanded clay in bags and for a cube: a comparative table

At the claydite value affects the specific gravity. In addition, the price of the material depends on the manufacturer. The expanded clay is denser, the more expensive. An integral part of the price is also the volumes of purchased raw materials. When it comes to large batches, then it is better to buy vrossyp expanded clay. The price will be several times lower. There is a difference in the packing of expanded clay: the price per bag of 50 kg will be different from the cost of a bag of 25 kg.

Useful advice!The weight of 1 cubic meters of expanded clay filler depends on its functionality. The smaller, the higher the thermal conductivity effect, i.e. more heat will conduct, having a lesser degree of thermal protection.

keramzita fee per bag and in bulk may be somewhat different. This is evidenced by table compiled based on the amount of material required.

Average prices of expanded clay:

kind of expanded clay	Fraction granules, mm	Price for 1 bag weighing 50 kg / RUB.	Price for 1 m3 of expanded clay with delivery
Sand	0-5	100-140	1900-2100
fine gravel	5-10	90-120	1800-2000
coarse gravel	10-20	70-110	1650-1900
crushed stone	20-40	60-85	1500-1600

The biggest price range cube of expanded clay and the packed material is observed with respect to gravel fraction 10-20, since the raw material is most popular. It is produced by many manufacturers of different material with different densities. Due to the versatility of its raw materials used in the insulation of various constructions. Such expanded clay is light enough and reduces heat loss by an average of 70%.

Price of expanded clay blocks and its components

For the purpose of rapid construction of the warm walls often used expanded clay blocks. Their types depend on the destination: for external walls, partitions, for additional insulation. Lightweight aggregate blocks differ from pure expanded clay so that their structure contains impurities of cement and sand. They represent a monolithic product. The composition and size of controls GOST 6133-99. Ordering material for a variety of purposes, should be taken into account the width and thickness of the block.

In accordance with selected parameters keramzitoblokov which may have dimensions 39h18h19 cm or 40h20h20 cm. Walls of keramsit with proper selection of the material can last more than 50 years. The material for the partitions is characterized by parameters 39h9h19 cm. Other product name - semiblock. Sometimes the blocks are the foundation for the construction of wooden houses.

The cost of the material depends on its kind, form, and the composition and impurities. Cheaper to buy units in the factory than the dealers. The mediators also regulate prices in different regions. The cost of building block at the plant is on average 36 rubles - and 20 rubles semiblock. The margin at the middlemen reaches 15-18 rubles apiece.

When buying keramzitoblokov need to figure out a nuance, as the delivery. It should be clarified whether its suppliers provide or need to organize the export of their own. It is important to take into account the number of purchased units, as individual plants release only the material in bulk. Therefore, if you need a small amount of material will have to use the services of second-hand dealers.

Useful advice! The correct choice of units depends not only on the efficiency of construction and its strength, but also the total cost of materials.

Where to buy expanded clay in bags and how to save on shipping

The most profitable option to buy expanded clay - directly from the manufacturer. An exception intermediaries in the trading chain saves on the bag material up to 25%. This is due to the fact that the organizations involved in the sale include the cost of transportation costs, storage, payment of rent, labor movers and sales agents, and so on. D. In addition, dealers make the product margin, taking into account the economic risks.

In Russia, there are many factories for the production of expanded clay, the most popular among them - Ltd. is "mélisey" in Kursk, Alexinsky expanded clay plant, the plant "Expanded clay", located in Serpukhov. Also worth mentioning is "Azarovsky plant wall materials" in Kaluga and CJSC "Experiment" in Kostroma.

Buying a bulk bag is much more profitable. For example, expanded clay kilogram with a fraction of 5-10 mm in a shallow (kilogram) in the multiples cost 6-8 rubles, and the price in the packaging 50 kg - only 2 rubles.

Single cost of shipping material. The farther the point of sale, the more expensive transportation. If you intend to purchase small amounts of coarse gravel, the best bags to transport on their own passenger transport. If you want to buy a concrete block 0.5 in 50 kg bags in large quantities, then take it yourself to be quite expensive. After all, it is necessary to find a special spacious transport and to pay for its operation. In this case, better to deal with the seller, providing goods delivery service.

Where to buy expanded clay on favorable terms

One option for a bargain can be a purchase of insulation material, used. Expanded clay re-use can be purchased from companies that are engaged in the dismantling of old buildings and removal of construction waste. The price of a cube of expanded clay, used can be half the price compared to the material from the manufacturer.

Buying recycled, you should pay attention to his condition. Crushed major factions must pass the sorting, eliminating waste and crushed particles. Therefore, better to give preference expanded clay, which served a certain time on the roof insulation. Such material would not yield excessive mechanical and weather resistance, so even after prolonged use are well conserved. Expanded clay reuse is suitable for pouring the foundation or insulation for ceilings.

Useful advice!You can save a significant amount of money in the wholesale ordering material. Therefore, prior to the start of construction work it is advisable to calculate the total amount of insulation for the entire building.

If you decide to self-purchase, you first need to conduct monitoring of product prices, to study additional terms and possible discounts at various outlets. In such matters, will be superfluous advice and recommendations of friends on the Internet.

It should also take into account the seasonal factor. In the spring and summer there is a period of active building - materials and price increases. Therefore it is better in advance, in the fall or winter, buy expanded clay in bags. The price will be cheaper by a quarter, and the packed material is well kept.

How many cubes in a bag of expanded clay: calculation of the volume of material

In order to purchase the material was really beneficial and economical, is required to calculate the necessary amount of expanded clay. As mentioned above, the weight and volume depend on the density and granule fraction. The most common packaging expanded clay - 50 liters, at a ratio of 0.05 m³. It turns out that the price per cubic meter of expanded clay is equal to the value of 20 bags of the middle fraction of the material.

Calculate the right amount, and calculate how many cubic meters worth of expanded clay, can be based on such parameters:

The volume of bags l	Number of bags in the cube	The volume of the bag, m³
50	20	0,05
40	25	0,04
25	40	0,025

For a different type of work different amount of material required. For example, the need for wet screed part cement, 3 parts sand, 4 parts of expanded clay. This means that 30 kg of concrete require 25 kg of expanded clay. Next determined total. For effective insulation screed layer should be at least 10 cm. This parameter is multiplied by the area of ​​the room and divide by the volume of the bag.

Sample calculation for a room of 20 square will look like this: 20m² x 0.1 m / 0,05m³ = 40 bags. Thus, the total price of expanded clay floor will be equal to the cost of 40 bags a fraction of the material.

Thus, choosing a concrete block as a heater, to trust well-proven in the construction market manufacturers and their distributors. When it comes to large volumes, it is best to buy material in bulk. However, during prolonged transport and storage conditions, no preference is recommended to give clay gravel or rubble in bags. In case of doubt in their own abilities whole process best left to experienced professionals.
