Laboratory service
In our laboratory, building materials are tested on the basis of certain sequential stages, and the entire testing process is continuously monitored by our specialists.
First, the material is reviewed. At this stage, all the properties of the material are determined. Then it is determined whether the composition of the material changes under different conditions, and if so, to what extent. At the next stage, the conditions of the material delivery process are controlled. At the last stage, the correct use of the material is controlled.
The following construction products are tested in our laboratory:
- Concrete mixes
- Heavy and fine-grained concretes
- Construction solutions
- Natural dense rock, gravel and crushed stone
- Sand for construction work
- Additives for concrete
Types of testing of construction products
1) The following are defined in concrete and concrete mixtures:
- Mobility (fluidity or stiffness)
- Porosity
- Folding
- Durability
- Frost resistance
- Water permeability
- Abrasion resistance
2) Test types for determining the composition of granules are:
- Gravel particles
- Dust and clay particles
- Layered and needle-shaped granules (flatness, length and breakage of these granules)
- Cracking
- Weak rocks
- Frost resistance
- Bulk density
- Humidity
- The right density and water absorption
- Organic mixtures
3) Determining the composition of sand grains and the dimensions of the filler material is carried out by the following types of tests:
- The right density
- Density
- Dust and clay particles
- Humidity
- Organic mess
4) Test work on chemical additives:
-
Determination of efficiency of chemical admixture in concrete
