Liquid concrete glass universality silicate mixture

In order to impart additional properties in concrete has added various materials and solutions. For faster tenacity, water resistance and moisture taken to make potassium or sodium silicate, called water glass, or soluble. For concrete, it is used in the composition of the cement mixture, necessary for waterproofing concrete surfaces. About the features of the material and the rules of its use, this article will tell.

Composition and scope waterglass in concrete

The phrase "liquid glass" is familiar to many, but not everyone knows what it consists of the mixture and for what purpose it is used. An aqueous solution of potassium silicate or sodium opened yet alchemists in the Middle Ages, but the first plant for its production appeared only in the XIX century. Then it began its widespread use in the construction industry.

Producing material by fusing sand and soda, or by connecting the proportions of ground silicon with hot caustic soda. At the output give a translucent viscous substance white or yellowish in color, hereinafter waterglass. The composition solution may include sodium or potassium silicates, and mixtures thereof.

Material having different properties, are widely used in construction for waterproofing concrete surfaces. For this purpose, the concrete is carried out coating liquid glass. Cement is applied directly on a silicate solution which is absorbed into the surface. When drying agents are clogging all pores of concrete, protecting it from moisture. The maximum effect is achieved by applying several layers of this composition.

This material is used as admixture to a concrete solution. Concrete with addition of waterglass is highly waterproof, solidifies much faster. Therefore, it should be used for some time. In addition, waterglass use to produce monolithic concrete blocks of different brands and of different sizes.

Application of the substance in various fields due to the benefits of silicate material, including isolated:

• high degree of penetration and adhesion;
• formation of solid waterproof film on the surface of material to be coated;
• a small consumption of material in the solution;
• affordable price means.

To that was added into the concrete waterglass: feasibility of material

Superior quality concrete with the addition of a solution of water glass is that the mixture quickly sets and provides a high degree of protection against moisture. However, it should be noted that the strength of monolithic structures thereafter decreases.

Useful advice! Use of a cement mixture with the addition of water-glass design allows successful repair of concrete, asbestos cement, ceramics and even carry out restoration of cast iron pipes.

The most appropriate to apply the silicate-concrete solution to such needs:

• sealing cracks with liquid glass in concrete, brick wall, for insulation joints;
• urgent repair concrete foundation, destroyed by excessive moisture;
• consolidating concrete with liquid glass in the ceiling, to connect beams and other elements.

In these cases, the cement is added a solution of water glass in a proportion of not more than 1: 1. Further kneaded slightly solution and immediately used, since a mixture of cement and silicate dries very quickly. Proper materials allow ratio permanently eliminate defects or impart additional strength to concrete structures.

Addition of water-glass in concrete is appropriate to create a foundation on the ground where the soil contains high levels of acid waters. This ensures an increase concrete resistance to the ravages of moisture. Successfully fill such a foundation provided by the following rules:

• adding sodium silicate in the concrete mix should not exceed 3%;
• produce additional and thorough basement waterproofing with other materials.

Liquid Concrete Glass: Instructions for use and production of a mixture of

Prepare a mixture of cement and water glass is possible even in the home, while complying with several requirements. Violation solution manufacturing technology may result in the formation of cracks in the concrete.

Water glass to be added to the dry mixture. For this, first in the right proportions connect all the dry ingredients and stirring them thoroughly, without using water. Then slowly poured into the water glass, previously diluted with water.

It is necessary to adhere strictly to the ratio of all ingredients in the preparation of the solution according to the recipe used for the specific type of work. For example, in the case of an amount of glass in the concrete it should not exceed 25% of the total weight of the mixture. ratio can be 1 for preparing primers using the cement composition and silicate glue: 1.

It should be noted that the acceleration speed and curing density of the solution affects the liquid concrete is glass. Instructions for use recommends cooking the mixture in a small amount and use it quickly.

The setting time depends on the amount of waterglass added to the concrete. If the mixture contains 2% of the substance, then it starts to set an hour, if 5% - then after 40 minutes. The proportion depends on the solidification process. If the solution is added a 4% silicate adhesive, the strength of the concrete after complete solidification will decrease by approximately 25%. However, if the concrete will contain only 3% of sodium silicate, the structural strength increase.

Useful advice! Sodium silicate besides the waterproofing function, possesses bactericidal and antifungal properties. The chemical composition of the material - unsuitable environment for the development of any life.

Technological features of mixture and impregnation of concrete types waterglass

Waterglass solution, the kneaded cement in M400 at 20 ° C, starts to set in 2-3 hours and completely solidified in a day. Over time, the monolithic substrate only prochneet. The maximum effect of hardness achieved after a maximum of 4 weeks. Water glass is also used as impregnating different surfaces allowing their smoothness, evenness and waterproofing. Concrete processing liquid glass is carried out for such structures:

• concrete floor;
• flat roof;
• wells;
• swimming pools;
• cellars;
• caps;
• concrete walls and ceilings.

The impregnation process includes several steps. First of all, the foundations required training. To this end, the surface is thoroughly cleaned of the old coating, paint, debris, dust and dirt. Further, the cleaning is carried out with a wire brush, a base coated with bitumen emulsion layer in 2mm. Based allow time to dry.

Then, a surface impregnation with the water glass solution. The proportions of sodium silicate in the concrete depend on the type of surface (in accordance with the instructions for use). If the surface horizontal, then it is applied a layer of 2-3 mm and smooth mixture spatula. Fill the floor and ceilings are produced in several layers, making a break for a number of hours. Use the surface can be a couple of days.

During the work must adhere to a set of recommendations. In particular, it is necessary to distribute the solution evenly. The coating should be done as quickly as possible, preventing the hardening composition. It provides reliable impregnation putting the mixture in two or even three layers. For insulation of walls and ceilings using a special spray that promotes uniform distribution of the solution. Coated surface in two or three layers.

As cover waterglass concrete floor

Water glass is used not only for priming, impregnating surfaces, but also as a coating. For this purpose, a special solution is prepared comprising from fine filler, sand, was added to it the active silica, water glass and water. The ingredients were mixed with a mixer construction. The material obtained should be stringy and thick.

Solutions with waterglass to a concrete floor used for applying a protective waterproofing layer floors, walls and ceilings in rooms with high humidity: bathrooms, sauna, laundry, pool, or baths. It is also recommended to use these mixtures in basements.

Before you apply the water glass on the concrete surface to be treated thoroughly cleaned and leveled. As topcoat waterglass is used as a strong hydrophobic solution. Surface coating is carried out by pouring on the covering, which are formed strips mounted parallel to the wall.

Useful advice!Water glass has high thermal conductivity. Therefore, the material is often used to provide additional insulation. Addition of water-glass in concrete is in the right proportions provide a high thermal insulation surface which can withstand temperatures up to 1200 ° C.

The quality of work depends on the uniformity of distribution of the material. This can be done with a special spiked roller, trowel and a doctor blade with a long handle. layer size is 2-4 mm. Given the short drying time, water glass on the concrete, the work should be done fairly quickly. It is better to divide the coated area into sections, and the whole process - into several stages. After preparing the floor surface painting produce concrete with liquid glass.

How to add water glass in concrete: recipes compositions

Depending on the intended purpose are prepared waterglass ratio. The main thing in this case - the responsibility and accuracy. Universal impregnation recipe mixture provides silicate with water in a ratio of 1: 2. There are several options developed by experienced builders who are time-tested.

If a silicate solution is used as a primer, then the mixture is prepared in proportions of 1: 1 (with cement and adding the desired amount of water). That is, 1 kg of cement was added 1 kg waterglass and gradually poured an amount of water to the resulting mixture was convenient primed surface. In the case of rapid solidification of the solution it can be some time to add a little water.

Waterproofing wells liquid glass is combined with carefully sifted sand in the ratio 1: 1. The resulting mixture is coated onto the well walls.

In concrete underground premises provide reliable hydraulic protection adding waterglass into the concrete in a ratio of 1 l of silicate glue in 10 liters of cement slurry. Such structure ensures reliable insulation of basement walls and floors located underground. The refractory mix is ​​prepared as a cement-sand mortar with a small amount of sodium silicate.

Wood preservative was prepared as follows: liquid glass mixed with water in equal proportions. In this case the tree is formed slippery protective film, which is not subject to painting. For this reason, such a solution should not be applied to concrete walls.

Various types of impregnation prepared mainly starting from such proportions: 400 ml of waterglass per 1 liter of water. The subsequent layer is applied after 20-30 minutes - namely through such a time interval as dry waterglass concrete.

Liquid concrete glass: customer reviews and expert

On the Internet you can find plenty of reviews that characterize silicate solution mainly on the positive side, though there are negative opinions. In particular, the material is considered environmentally friendly, and its application in violation proportions can lead to cracking of the concrete surface. Individual users do not like the silicate-concrete mixture quickly grasped. For example, there are cases when an inexperienced builder kneaded mortar with addition of water glass in a ratio of 25%. When pouring the screed mixture froze immediately, but after a day simply crumbled into dust. I had to re-train solution. In this case, the main error is the failure of the master aspect ratio.

Other reviews, on the contrary, is characterized by water glass as an excellent means for waterproofing the screed. Masters noted that after treatment the surface is much less covered with dust and practically erased, as well as indicate the fire safety silicate-concrete solution.

Useful advice!Builders are strongly advised to work with the material very quickly. To create ties require some experience and skill, because this process does not tolerate delay.

Some believe that the use of additives such as water glass, it is appropriate in those cases when it is necessary to enhance the technical characteristics of certain materials. For example, appropriate to its use in casting a foundation for garden houses, located on the ground with high humidity. Thus, opinion is divided about the liquid glass in concrete: the pros and cons of the material offer their customers positions.

Liquid Concrete Glass: rules for the use and protection measures

Silica material does not burn, it is not explosive and does not have toxic effects. Before using liquid concrete glass, it is necessary to prepare a specific set of tools: a special container compounding mixer building, brushes, brushes, rollers, and gloves, and for spraying on the wall or ceiling - gun.

Use of such a universal remedy in conjunction with concrete requires compliance with certain security measures. Liquid glass, while not toxic, but getting into a spray to the mucous membranes, can cause irritation. Therefore, when sputtering is necessary to take care of the protection of the eye and upper respiratory tract. We must work in a well-ventilated area.

Avoid contact with the solution on open skin areas, so work better in the sealed clothing, hats, and recommended to use personal protective equipment. Penetration of the substance into the eyes may cause burns, so in this case you must rinse immediately with plenty of water and seek a medical facility for help. If contacts skin enough wash it with warm soapy water and rub baby cream.

Container used for dilution, will not be applied in everyday life. Therefore it is better to take the packing buckets from beneath fillings or use cut plastic five-liter jar.

You need to take care of the conditions of storage of ready solutions. It should be cool and dry place with temperatures 5 to 40 ° C. It should be noted that the waterglass - cold-resistant material that can withstand a temperature parameter to -30 ° C.

Liquid concrete glass: the price and quality of products

liquid glass cost for concrete, compared with other materials is quite affordable. In particular, pyatnadtsatilitrovaya canister will cost up to 300 rubles, or an average price of 50 rubles. per kg. Wholesale price, respectively, will be even less. For example, dvuhsotlitrovy tank is approximately 4.5 kb. rubles. When buying wholesale (for large volume of work) should be borne in mind that it will take some shipping costs.

If you decided to attract professionals, you should consider the cost of their labor. The total cost depends on the type and scope of work. For example, services for the implementation of the waterproofing layer will cost about 1,300 rubles. per m³.

Useful advice! Liquid glass can be a lifesaver in resolving the issue as to how to replace a plasticiser for concrete. Due to the application of concrete silicate adhesive becomes water-repellent ability and can resist the aggressive environment. As the plasticizer of sodium silicate is added in a proportion of 1:50.

Use of waterglass for the purpose of waterproofing and strengthening of concrete is the most efficient and best solution in terms of technology and in terms of price. The main condition - is the observance of the application instructions, which regulates not only the order of the work, but also strict adherence to the proportions of the materials. Sodium silicate mixture better administered in solution rather than using a separate paint material.

Use of waterglass for external processing considered most budget embodiment, but is aesthetically inferior coating significantly more expensive analogs. If it is necessary to impregnate the concrete with minimal cost, liquid glass - optimal solution.
