MATERIALS TESTING

This section serves the physical and chemical testing of soil and rock rubble, stone and marble. Cement, ceramic tile, water, cement and microsilica, refractory, lime, plaster, concrete design, products, and concrete admixtures, bitumen hot bitumen materials and blends design. And the drilling and non-destructive tests for reinforced concrete under the supervision of experts in the field laboratory or private laboratory inside the company.

Field Sampling
This includes taking samples of aggregate from stock piles, of fresh concrete, tack coat and hot asphalt, soils and building blocks. Cores are cut from asphalt for routine QC, while from concrete for determinations of strength or chloride, sulphate and carbonation. Other construction materials include concrete mixing water and pavers.

Field Testing
Typical tests include the electrical and thermal resistivity of soils and field density by either sand replacement or nuclear gauge, site CBR, plate load test. Properties of fresh concrete usually determined are slump, temperature, air content and density.

Laboratory Tests
Measurement of density and compressive strength of cylinders and cubes and the grading of aggregate are routinely carried out. Other concrete tests include core evaluation (e.g. strength, density, chloride and sulphate contents, and carbon dioxide penetration) as well as rapid chloride permeability, water "penetrability" and volume of permeable voids. Asphalt samples are tested for composition, density and layer thickness.
