Investigation of raw material for the manufacturing of sulphate-resisting cement in Darukhula Nizampur, NWFP, Pakistan.

Raw material (limestone and clay) of Darukhula Nizampur North West Frontier Province (NWFP), Pakistan has been used in the raw mix design and manufacturing of sulphate-resisting cements (SRC). The resulting cements were found to contain all physical and chemical parameters in good agreement with the British and Pakistan standard specifications. The studied parameters of the resulting SRC include compressive strength, consistency, setting time, Le Chatelier expansion and insoluble residue. It was found that the raw material available at the study area meets the standard specifications and the area is feasible for the cement plant installation. The area can provide raw material that is quite sufficient for the operation of a cement plant. [ABSTRACT FROM AUTHOR]
