Cement Particle Size and Stability - HORIBA

Many cement labs have switched to using laser diffraction to measure the particle size of their cement. This technology is fast, easy to use, flexible, and repeatable. HORIBA offers two laser diffraction analyzers to the cement industry: the full featured and automated LA-960, and the smaller, more economical LA-300 .

Cement Stabilisation - an overview ScienceDirect Topics

The differences in costs of the soil-cement stabilization layer are about f 1,-/m 2 in relation to repak and f 40,-/m 2 in relation to sand-cement. Soil-cement is the economical most benificial option. The use of cement is a critical aspect for an economic advantage. A lower content of cement will give a substantial reduction of the costs.
