REPLACEMENT OF CEMENT WITH DOLOMITE POWDER:

2018-10-10  Replacement of cement with dolomite powder is found to improve the strength of concrete. The maximum replacement percentage of cement with dolomite powder is found to be 5% and at this replacement level, the maximum increase in the 28th day compression and flexural strength were found to be 5.84% and 2.73% respectively.
