Jet mill grinding of portland cement, limestone, and fly

2013-11-1  When investigating the OPC/limestone, the grinding effect was more pronounced at lower w/p of 0.35 than at higher w/p of 0.50. This was due to the fact that in the lower w/p mixtures, the replacement of cement by limestone allows the remaining cement to hydrate more completely, resulting in a higher degree of hydration.

Jet mill grinding of portland cement, limestone, and fly

The inter-ground OPC/limestone mixture shows accelerated initial hydration at water to powder ratios (w/p, where powder = cement + limestone) of 0.50 and 0.35 when compared with the samples before grinding. At the lower w/p of 0.35, the OPC/limestone mixture appears much more efficient.
