Mix design with water reducers

摘要

1. M-25 grade concrete without water reducers PPC and OPC having the same materials requires 190/0.5 = 380 kg/m~3. 2. With the use of superplasticiser the savings in cement and water is 78 kg/m and 42 lit/m~3 for PPC and OPC. 3. In the fly ash concrete, the savings of cement and water are 143 kg/m~3 and 49 lit/m~3 . From this, it utilizes 101 kg/m~3 of fly ash which is a waste material.
