Sampling and Testing Aggregates

Sampling and testing aggregates ensures they meet specifications for construction projects, involving collecting representative samples (from stockpiles, belts, trucks) following standards like ASTM D75 or AASHTO T2, then reducing them in the lab for tests like sieve analysis (particle size), specific gravity, water absorption, and soundness to determine suitability for concrete, asphalt, or ba…

Specific Gravity of Fine and Coarse Aggregates

Specific gravity (SG) for aggregates, a measure of density relative to water, generally ranges from 2.5 to 3.0, indicating quality, with higher values suggesting stronger, denser material, crucial for concrete mix design and volume calculations. Testing involves weighing dry, saturated surface-dry (SSD), and submerged samples to find Bulk SG, Apparent SG, and water absorption (pores holding 1-2…
