Clay Lumps and Friable Particles This test is used to derive the percentage by mass of friable particles and clay lumps in aggregates, which are to be used for making concrete. The method involves weighing the specimen, then removing clay lumps by soaking and gentle manual abrasion, followed by are-weighing the sample.

Effects of slurry on stickiness of excavated clays and

9/1/2016· If the clay aggregates are penetrable by water, the water will weaken the surface of the clay lumps in a relatively short time, making them prone to sticking to other lumps or to excavation tools surfaces. Fig. 17a shows evolution of the Opalite clay lump structure when submerged in different liquids. After being submerged in water, the lump surface weakens relatively fast and after a certain period of
