Concrete Mix Design Just Got Easier | Giatec Scientific Inc

For example, reducing the water/cement ratio will increase the strength of the concrete and provide better durability. However, decreasing the water/cement ratio can also significantly reduce the workability of the concrete. In these cases, one possible solution is adding water reducer to the mix (see Step 7). Using the Help option, you can ...

What is Water Cement Ratio? - Guide & Calculation – Civilology

What is Water Cement Ratio? Water Cement Ratio means the ratio between the weight of water to the weight of cement used in concrete mix. Normally water cement ratio falls under 0.4 to 0.6 as per IS Code 10262 (2009) for nominal mix (M10, M15 …. M25) We all know that water cement ratio will directly affect the strength of concrete.
