gravel density and other indicators for the professional approach

types and characteristics of gravel

Natural option is a fairly loose rocks, artificial - a specially designed material that meets all the requirements of modern construction.Grains with a smooth surface have a size of 5 mm to 7 centimeters.Rounded grains are used for mixing concrete, important in laying the foundation, as well as for the construction of roads or trails in the artificial landscape design.

Natural gravel can contain fragments of minerals, up to 1 cm.Experts material divided into several groups according to the value of each component: fine material - from 1 to 2.5 millimeters, the medium - from 2.5 to 5 millimeters and large - from 5 millimeters to 1 centimeter.

The calculations also important to consider the specific weight of gravel, expanded clay embodiment has indicators from 200 to 800 kilograms per cubic meter, shungizitovy - from 400 to 800 kilograms per cubic meter.

Tricks When Buying

First of all, the builders are interested in the gravel, which can be used for concrete filling, is also an active gravel is used as soundproofing, insulating and filter material.To overestimate the importance of gravel difficult, because you need it in any road works, the material allows you to create a solid basis and the amount of other elements provides a reliable, low-maintenance coating.

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

When you purchase the material you need to consider the humidity factor, water-saturated gravel weighs more, but experts advise to buy only well-dried material in order to avoid problems in the future.As a rule, the weight of the gravel is measured in cubic meters and is located at around 1400 kg.

Options material with different impurities may weigh slightly more, the buyer must carefully check the quality to successfully complete construction of the facility.

During the construction do not forget about these nuances

conducting tests of the material being prepared for sale, specialists will consider a variety of gravel, trying to sort it out, not only in size but also in physical properties largely depend on the proportion of impurities.During construction it is important to know what is the bulk density of the gravel, according to tests carried out, it is 1.56 kilogram per liter.

In other words, this figure shows the density is poured on the surface of the material without additional sealing .

Considering gravel, technical specifications which are ideal for the creation of dense building foundations and roads, it is necessary to pay special attention to the shape of the individual grains, it should be as homogeneous.Crumbling inserts make the material unsuitable for use in construction.A large amount of impurities may indicate that the defective gravel.

Another important indicator that helps navigate the builders work - thermal conductivity of the gravel is 0.93 watts per square meter.The low cost of the material and good performance make gravel one of the most popular building materials.Considering the properties of rocks, its strength can be identified, the ability to use as a filter, environmental friendliness and durability.
