The nominal concrete mix of a fixed proportion of cement, sand and aggregate provide considerable variation in strength resulting in the poor or over-rich mix.

Learn MoreWater/cement ratio theory states that for a given combination of materials and as long as workable consistency is obtained, the strength of concrete at a given age depends on the w/c ratio. The lower the w/c ratio, the higher the concrete strength. All materials used for a design including the water quality should be to a high standard.
