method of grinding limestone

Influence of grinding method and particle size ...

2013-12-20  The benefits of using limestone as a partial replacement of Portland cement (PC) are well established in the literature. Economic and environmental advantages by reducing CO 2 emissions are well known. This paper describes the influence of the producing method (intergrinding or separate grinding) and particle size distribution on properties of Portland-limestone cements (PLC).
