Loose sedimentary rocks widely used in construction, especially private construction, are called grus. The nature of its origin is the result of the natural destruction of rocks, for example, under the influence of water, temperature and weathering. The product is also obtained by crushing by technical means. On the surface, it is a loose scree, at depth it looks like fractured rock.
Material specification
Dresva - what is it? Fragments of rocks characterized by high water permeability, low strength and low moisture capacity. The material is of natural origin, therefore it does not have a negative chemical impact on the environment, it is harmless to humans, animals and plants. The composition is quite homogeneous, the color varies from yellow to gray. Fractions ranging in size from 2 to 20 mm, something between sand and fine gravel.
One of the main advantages can be attributed to a fairly low price for crushed stone screening, which is explained by the lack of expensive mining methods. In fact, gruss - what is it? This is a by-product, and therefore its price is much lower in comparison with crushed stone. Although in some regions of Russia, for example, the Sverdlovsk region, raw materials are extracted by one of the most labor-intensive andcostly methods.
In general, all types of material tend to shrink, are characterized by incombustibility and good drainage properties, which are indispensable for eliminating flooding.
How grit is used
Because of the low strength, it is not possible to use in large building construction, but there are many other applications. To cover the asph alt pavement, the product is mixed with crushed stone or gravel. Paths are strewn in city parks and squares, gruss is used as a mineral fertilizer for plants in the horticultural sector.
The material is used as an effective abrasive for polishing and cleaning metals, in the construction industry as a cushion (base) for laying paving slabs and concrete production, as well as:
- filling sites;
- in lime and cement production;
- filling concrete;
- in road construction.
In short, grub – what is it? Continental product as it is formed without the influence of water, and a special material used to build the foundation of small structures.
Fighting ice
Ice, puddles, mud - everyone is familiar with the situation when it is impossible to walk down the street and not get dirty or fall, go into a room or park a car normally. Coping with the problem on a city-wide scale is the task of public utilities, but gruss will help to do it on your own site. What is it like when the territory is strewn with gravel, everyone has an idea, but noteveryone knows it's her.
Processed sidewalks are protected from slips, dirt and puddles. Among the offers on the market, the delivery service is especially popular, the material is usually ordered in large quantities - this is more profitable.
The anti-icing qualities of gruss are successfully used for sprinkling footpaths, playgrounds and sidewalks, which helps to avoid many accidents. The characteristic of the product depends directly on the properties of the rock that formed it, this circumstance affects the price of the material.
