The density of bentonite can significantly affect bentonite performance. The increase of bentonite density will result in improving the bores or excavation stability.

CHAPTER 8 SLURRY SEALS - CSU, Chico

The slurry mixture contains asphalt emulsion that breaks onto the pavement surface through heterogeneous or homogenous flocculation. The asphalt particles coalesce into films, creating a cohesive mixture. The mixture then cures, by loss of water, into a hardwearing, dense-graded asphalt/aggregate mixture that is bonded to the existing pavement.

Slurry Transport - Minimum Flow Velocity

A suspension of solid particles in a liquid, as in a mixture of cement, clay, coal dust, manure, meat, etc. - with water is often called a slurry. In transport systems for slurries it's important to avoid settling of solids by keeping the fluid velocities in the pipe lines above certain levels.
