  • Concrete Mix Ratios (Cement Sand Gravel)

     · Water/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.
