Kinds and characteristics of gravel

The natural variant is a fairly loose rock, artificial - a specially created material that meets all the requirements of modern construction. Grains with a smooth surface have dimensions from 5 millimeters to 7 centimeters. Coiled grains are used for mixing concrete, are important when laying the foundation, as well as for the construction of roads or artificial paths in landscape design.

Natural gravel may contain fragments of minerals, up to 1 centimeter in size. Experts divide the material into several groups according to the size of individual elements: fine material - from 1 to 2.5 millimeters, medium - from 2.5 to 5 millimeters and large - from 5 millimeters to 1 centimeter.

In calculations it is also important to take into account the specific gravity of gravel, the claydite variant has the indices from 200 to 800 kg per cubic meter, shungizite - from 400 to 800 kg per cubic meter.

Little tricks when buying

First of all, builders are interested in gravel, which can be used to fill concrete, and gravel is actively used as a soundproof, heat insulating and filtering material. Overestimate the importance of gravel is difficult, because it is needed in any road works, the material allows you to create a solid foundation and in total with other elements gives a reliable, unpretentious coverage.

Before the team of builders starts work, calculations are carefully carried out. Taking into account the bulk weight of gravel - 1.3 grams per cubic centimeter, it is possible to estimate the density of the resulting coating and its physical properties.

When buying a material you need to take into account the moisture factor, gravel saturated with water weighs more, but experts advise buying only carefully dried material to avoid problems in the future. As a rule, the weight of gravel is measured in cubic meters and is at 1400 kilograms.

Variants of material with different impurities can weigh somewhat more, the buyer must carefully check the quality to successfully complete the construction of the object.

Do not forget about these nuances

When testing materials prepared for sale, specialists necessarily take into account a variety of gravel, try to sort it not only in size, but also in terms of physical properties, which largely depend on the proportion of impurities. When building it is important to know what the bulk density of gravel is, according to tests conducted, it is 1.56 kilograms per liter.

In other words, this figure shows the density of the material poured onto the surface without carrying out an additional seal .

When considering gravel, the technical characteristics of which are ideal for creating dense building bases and roads, special attention should be paid to the shape of the individual grain, it should be as homogeneous as possible. Crumbling inserts make the material unsuitable for use in construction. A large number of impurities can indicate that gravel with defects.

Another important indicator that helps builders to navigate the work is the thermal conductivity of gravel, which is 0.93 W per square meter. Low material cost and good performance make gravel one of the most popular building materials. Considering the properties of gravel, we can distinguish its strength, the possibility of using as a filter, ecological purity and wear resistance.
