Aggregate Testing Equipment

Aggregates account for 60 to 80 percent of concrete volume and form the structural skeleton of asphalt, base course, and drainage systems. Their gradation, durability, and specific gravity directly control mix performance, which is why standardized aggregate testing equipment is a non-negotiable step in material acceptance and quality control.

Gradation analysis per ASTM C136 (sieve analysis) and ASTM D6913 (gradation by wash) defines the particle size distribution that governs workability, strength, and density. Specific gravity and absorption, determined under ASTM C127, are essential inputs for mix design and volumetric calculations. Durability is assessed through abrasion testing — the Los Angeles machine method covers small-coarse aggregate per ASTM C131 and large aggregate per ASTM C535 — producing an abrasion loss value that predicts resistance to mechanical degradation. Each test requires specific equipment: test sieves in standard sizes, sieve shakers, pycnometers, and the LA abrasion machine with charge spheres, all built to the dimensional tolerances the standards specify.
