Sometimes effects similar to those achieved through the addition of admixtures can be achieved by altering the concrete mixture reducing the water cement ratio adding additional cement using a different type of cement or changing the aggregate and aggregate gradation Five Functions Admixtures are classed according to functionA simple method of concrete mix design based on flexural strength for normal weight concrete mixes is described in the paper INTRODUCTION Usual criterion for the strength of concrete in the building industry is the compressive strength which is considered as a measure of quality concrete
