SelfCompacting Concrete
mix proportions, it becomes necessary to evolve a procedure for mix design of SCC. Okamura and Ozawa have proposed a mix proportioning system for SCC [3]. In this system, the coarse aggregate and fine aggregate contents are fixed and selfcompactibility is to be achieved by adjusting the water /powder ratio and super plasticizer dosage.

What are the Correct Concrete Mixing Ratios
Some basic mixing ratios for concrete are 1:2:3, 1:3:3, 1:2:4. These mixing ratios are based on the proportions of cement : sand : stone in that order. The ratio you use will depend on what psi strength you need. To make concrete there are four basic materials you need: Portland cement .
