ASTM-C142

Clay Lumps & Friable Particles

Applicability:ASTM C142 is a standard test method that determines the amount of clay lumps and friable particles in aggregates, which are considered deleterious materials that can negatively impact the performance of concrete and other construction materials.

Purpose: ASTM C142 focuses on identifying and quantifying clay lumps and friable particles, which are soft, easily broken down materials that can interfere with the bonding of aggregates and binder in concrete or asphalt.
