Aggregate Test Specifications

Measures the percentage of silt present in fine aggregates by volume. Excess silt can weaken the bond between cement and aggregate.

Determines the amount of silt in aggregates by weight. High silt content reduces the strength and durability of concrete.

Evaluates particle size distribution and calculates fineness modulus to assess the suitability of aggregates for concrete mix.

Indicates the density of aggregate particles compared to water. Essential for calculating mix proportions and quality control.

Measures how much water aggregate can absorb. High absorption indicates porous material which may affect water-cement ratio.
