How to Calculate Water Cement Ratio - The Concrete Network

The water to cement ratio compares how much water versus cement is used in a concrete mix. A low water cement ratio leads to stronger concrete, but is more difficult to work with. HOW TO CALCULATE WATER CEMENT RATIO. The water to cement ratio is calculated by dividing the water in one cubic yard of the mix ( in pounds) by the cement in the mix ...

Water/cement ratio - Concrete

Water/cement ratio. The water/cement ratio is the ratio of the weight of water to the weight of cement in the fresh concrete mix. The water/cement ratio controls the strength of the concrete and its permeability. The lower the water/cement ratio the higher the compressive strength and the lower the permeability of the hardened concrete.

Aggregate in Concrete - The Concrete Network

You can often save money by selecting the maximum allowable aggregate size. Using larger coarse aggregate typically lowers the cost of a concrete mix by reducing cement requirements, the most costly ingredient. Less cement (within reasonable limits for durability) will mean less water if the water-cement (w/c) ratio is kept constant.
