Civil Material Testing

HomeCivil Material Testing


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 carbonations. Other construction materials include concrete mixing water and pavers.


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


Measurement of density and compressive strength of cylinders and cubes and the grading of aggregate are routinely carried out. Other concrete advance tests include core evaluation (e.g. strength, density, chloride and sulphate contents, and carbon dioxide penetration) as well as rapid chloride permeability, water “impermeability” and volume of permeable pores, in addition to all these tests we are preparing the Mix design of Concrete in Many Grades for Concrete Plants around the Kingdom.

Asphalt samples are tested for composition, density and layer thickness, and verify the mix design for fresh asphalt Material.
