Does anyone know what is the ideal (optimum) ratio of

Moreover some conventional concrete maybe need 0 35-0 55 fine/coarse aggregate ratio limitations on the other hand in the self compacting concrete design as a special concrete we have to use the more fine materials like fine aggregate (0 65 by volume in total mix) powder ect and less coarse materials like coarse aggretgate (0 35 by volume Get price
