Stamps rubble - how do you know what a material?

As classified by brand rubble?

Despite the technological progress and the emergence of new technologies, there is a material which has not undergone any change and is used, as before, only improved equipment to work with him.Rubble - a bulk material of artificial or natural origin, obtained with the help of rock crushing technologies that have a high hardness.

For the production of concrete with high compressive strength is used rubble from high strength rocks, such as granite, for the manufacture of plaster and various concrete products use natural gravel weakness - dolomite, limestone.

rubble Brand strength is formed by its resistance to shatter, abrasion and compression.Tests are carried out in a special experimental drum.These effects are similar to those in power loads on gravel road surfaces during operation or construction activities.

Labelled it as follows:

• M1200-M1400 - high-gravel, where the content of soft rock should not exceed 5%;
• M800-M1200 - strong, weak content of grains of rocks does not exceed 10%;
• rubble M600-M800 has an average strength;
• M300-M600 - rubble weak strength;
• below M300 - very weak strength, which may contain in its composition to 15% of the grains.

What rubble will give us strength?

Crushed M1000 sufficiently strong material.Like the M1400, M1200, it is used for the construction of railways and roads, in the manufacture of concrete products, concrete mixes.This rubble brand has a high frost resistance, that is, carries more than three hundred freeze-thaw cycles.Products made of this material will be different strength, wear resistance and durability.

Rubble 800 different brands of surface roughness, which plays a crucial role in increasing the adhesion of cement and other ingredients in the manufacture of concrete.This brand has a high resistance to low temperatures, high humidity, and resistance to chemical and physical influences.

M800 Crushed granite, and therefore has a relatively high strength.Obtained by crushing stone cliffs and further screening.Used for external finishing works, ennobling the territory, strengthening the foundation and so on.

Weak brand rubble

Crushed mark 600 is extracted in open-pit limestone quarries, that is used blasting technology and further processing of rock.It is used for road construction and concrete production.

are frost resistant, water saturation and water absorption.As the calcareous material, dense compaction occurs, and this helps to avoid the formation of voids in the negative concrete mixtures.

This Brand rubble granite is much cheaper options, but on the qualities and characteristics is not much inferior.In addition, it is environmentally friendly material.If you can not buy a more expensive granite material, pay attention to the lime, which has a high physical and chemical characteristics.

Crushed M400 is widespread.It is characterized by low strength and low resistance to frost, but these qualities do not affect the execution of works, which use calcareous material.It is used mainly as a pillow or a ballast layer under the asphalt covering.

Crushed M200 very weak strength is used for the construction of roads with low intensity, as well as for decorating.This brand is probably the cheapest and unfortunately for her, not claimed, since the intensity of life is now almost everywhere is quite high, and requires reliable materials.
