The cost of exploiting the limestone: the major raw material constitute about 50% of the production cost which results in the high cost of cement. It therefore becomes imperative to bring down the cost of cement by investigating into alternative source of raw material for cement production and hence this project.
A favorable material price variance suggests cost effective procurement by the company. Reasons for a favorable material price variance may include: An overall decrease in the market price level. Purchase of materials of lower quality than the standard (this will be reflected in adverse material usage variance).
The quality of cement clinker is directly related to the chemistry of the raw materials used. Around 80–90% of raw material for the kiln feed is limestone. Clayey raw material accounts for between 10–15%, although the precise amounts will vary. Magnesium carbonate, which may be present in limestone, is the main undesirable impurity. The level

It is the raw material for a large variety of construction, agricultural, environmental, and industrial materials. Limestone is used in construction almost everywhere. In 2007, crushed limestone was 68% of all crushed rock produced in the United States. Also, limestone is the key ingredient in making Portland cement.
We produce these materials from natural deposits such as granite, limestone and trap rock. Our quarrying process typically begins with drilling and blasting the rock into smaller pieces. Next, the material goes through various stages of crushing and screening to produce the sizes and specifications desired by our customers.
