Concrete Mixing Ratios - How To Make Concrete (Cement, Sand ...

The less water you use to mix the concrete (somewhat dry but workable) the stronger the concrete mix. Accurate concrete mixing ratios can be achieved by measuring the dry materials using buckets or some other kind of measuring device. By measuring the cement, stone, and sand, you will have a consistent concrete mix throughout your entire project.

Sequencing in Mix Design - National Precast Concrete Association

The most important factor affecting sequencing is the type of mixer used. According to Paul Ramsburg, technical sales specialist at Sika Corp., precasters use a variety of mixers but most are central, stationary, batch-type mixers located at the plant. At computer-controlled central mix plants, initial blending occurs on conveyor belts and mixing occurs on one batch while the next one is simultaneously created. The number and type of mixing cycles in a sequence specify how long it takes to intro

Concrete Mix Ratios - Cement, Sand, Aggregate and Water

Concrete mix ratio of 1:3:3 – On mixing 1 part cement, 3 parts sand with 3 parts aggregate produces concrete with a compressive strength of 3000 psi. On mixing water with the three ingredients, a paste is formed that binds them together till the concrete mix gets hardened. The strength concrete is inversely proportional to the water/cement ratio.
