Raw materials for cement manufacturing

Minerals of natural origin as well as industrial products/by-products can be used for cement production as long as the main components of cement (Cao, SiO2,Al2O3,Fe2O3)are present in a required proportion on mixing and the impurities or undesirable components like alkalies, sulfur, chlorides, Mgo etc are below the allowable levels to ensure cement quality and operational stability.Cement mixes

How Cement Is Made

The most common way to manufacture portland cement is through a dry method. The first step is to quarry the principal raw materials, mainly limestone, clay, and other materials. After quarrying the rock is crushed. This involves several stages. The first crushing reduces the rock to a maximum size of about 6 inches.

The Suitability Of Limestone Aggregates For Use In

Crushing Limestone to produce fine aggregate results in the generation of a substantial amount of fine sizes (minus 0.075mm or #200 mesh) commonly referred to as dust. These fines do not aid in the production of good quality concrete and therefore must be removed from the sand before combining with Coarse Aggregate and cement.

Limestone Filler - an overview | ScienceDirect Topics

Limestone fillers are being used increasingly in cements and, more recently, as a mixer addition. EN197-1 (BS EN197-1, 2000) contains two classes of Limestone Portland cement, CEM II/A-L (or LL) and II/B-L (or LL). The former contains between 6 per cent and 20 per cent limestone and the latter 21–35 per cent limestone.
