PPT-Admixtures

Admixtures are material added to concrete mix in order to modify its properties Usually it is not more than 5 by mass of cement and should always follow the manufacturer recommendations Additives. Admixtures should never be regarded as a substitute for good mix design good workmanship or use of good materials 1 uses of admixtures The most common reasons for using admixtures in concrete are To increase workability without changing water conten Concrete is essentially made from five materials. . 1. Air . 2. Water. 3. Cement 1+2+3=paste . 4. Fine aggregate 1+2+3+4=grout or mortar . 5. Course aggregate 1+2+3+4+5=concrete . Definition. An . admixture is a material added to the batch of concrete before or during its mixing to modify its freshly mixed, setting or hardened properties. .
