How To Find The Right Concrete Mix

While concrete is a blend of Portland cement, sand and gravel, cement is the dry, powdered substance that is mixed with sand, gravel and water to become a binder for concrete. Mixing sand, gravel, water and cement in the right proportion is essential to producing durable, high-quality concrete.

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.
