The Materials Testing Lab provides testing services mainly for Soil Investigation (auger boring, standard penetration test and trial pits), Concrete Investigation (ultrasonic pulse velocity, Schmidt hammer, drilled core test, compressive strength including cube, block, interlock, and kerbstone), Soil Test (liquid and plastic limit, linear shrinkage, particle density, sieve analysis, in-situ density test, moisture dry density, Califomia Bearing Ratio, bearing capacity by plate load test, electrical resistivity, moisture content), Aggregate Test (Sieve analysis, clay lumps and friable, sand equivalent, bulk density, flakiness, elongation, particle density and water absorption, Specific gravity, crushing value, TFV, Los Angeles Abrasion Value, impact value, soundness, organic impurities), Steel Test (cross-sectional area, mass, tensile properties, bend and rebend, epoxy coating thickness), and Chemical Analysis for soil, aggregate, concrete and water (sulfate, chloride, pH, TDS).
