Effect of Admixture on the Compressive Strength of Composite Cement Mortar
The effect of superplasticizer on the development of composite cement based on flyash/limestone powder as per EN-197-2000 has been studied. Various mixes of fly ash and limestone up to 40% has been blended. The results have been compared with clinker of 43 grade ordinary portland cement used in the present study. 1 day strength of mixes with 5% and 10% limestone powder has been found to be is comparable to control. Further, it has been found that 28 days strength of mix with 15% lime stone powder and 25% fly ash gives more than 32.5 R required for composite cement. With the use of superplasticizer, strength has been found comparable or more in all the mixes at 1day to 43 grade OPC. X-ray diffraction (XRD) analysis of various mixes at different hydration times has also been evaluated.
