UTILIZATION OF BASALT ON THE CLINKERIZATION OF ORDINARY PORTLAND CEMENT CLINKER [PDF]
Al-Azhar Bulletin of Science, 2012 This study comprises the effect of basalt as a flux and mineralizer on the formation of Portland cement clinker, where it used instead of sand, iron and clay at constant lime saturation factor. Three mixtures were prepared, the first formed from original raw materials, in second mixture the sand and iron replaced by basalt and in the third mixture the ...
