Alternative Cement Milling Process

Dec 01, 2018 1. Introduction. The term “alternative cement clinker” as used here refers to a man-made mineral material that, when ground to a fine powder, is capable of reacting sufficiently rapidly with water and/or CO 2 in such a way as to produce a hardened mass which can be used as the binder in a concrete or mortar and which will harden rapidly enough to be adaptable to modern construction ...

This allows the contractor to utilize otherwise over optimum moisture content material on-site, instead of off-hauling this material. The process mixes cement into the existing site materials, up to 18 inches deep, creating a homogenous mix where the soil can react with cement and dramatically increase the compressive strength of the soil.
