Learn MoreThe ratio of the amount of water to the amount of cement by weight is known as ‘Water—cement ratio, and the strength of concrete depends on this ratio. Water affect the whole properties, the durability, strength of concrete to a great extent. Therefore, you need to use the amount of water very carefully in the mix.

Learn MoreWater-Cement Ratio is defined as the ratio of the weight of water to the weight of cement. Water/cement ratio as per IS 10262 (2009) for the concrete mix varies from 0.4 to 0.6. 0.7 w/c ratio is also used for pumped concrete. 0.5 w/c ratio indicates, that for every 100 kg of cement, 50 lit. of water is added.

Learn MoreConcrete mix ratios are the proportions of concrete components such as cement, sand, aggregates and water. These mix ratios are decided based on type of construction and mix designs. In this article we are discussing about concrete mix ratio and ideal mix concrete.
