Portland cement is the most common type of cement in general use around the world as a basic ingredient of concrete, mortar, stucco, and nonspecialty grout was developed from other types of hydraulic lime in England in the mid 19th century, and usually originates from limestone is a fine powder, produced by heating limestone and clay minerals in a kiln to form clinker, grinding

Influence of grinding method and particle size

Dec 20, 2013 · Abstract. 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 Portlandlimestone cements (PLC).

Don''t use Quicklime in Mortar Concrete Construction

This requires careful proportioning and grinding to control particle size. To control the expansion, these particles may also be coated to delay hydration. If particle sizes are too large, the lime will continue to hydrate and expand long after the grout has set, causing the mortar to break apart.
