WaterCement Ratio is defined as the ratio between the weight of the water to the weight of cement. In general terms w/c ratio means, how much water is required for the particular mix. We all know that the watercement ratio will directly affect the strength of concrete.

What is the ratio for mixing concrete? One of the best concrete mix ratios is 1 part cement, 3 parts sand, and 3 parts aggregate, this will produce approximately a 3000 psi concrete mix. The strength of this mix ratio is good for most concrete slabs, footings, steps, and foundation walls.

The ratio between the water and cement by weight is known as WaterCement Ratio. The quantity of water added to the cement while preparing concrete mixes has been known to exert tremendous influence on the quality of concrete. It was first discovered in 1918 Abram had evaluated this aspect of concrete proportioning and stated:
So, in this example, the ratio would be one part cement to four parts sand and five parts stone. A similar example of ratio in mass, would be 50 kg of cement to 200 kg of each sand and stone. If concrete is specified by strength, this is given in megapascals (MPa), or the pressure that concrete

LightBUILD Cellular Lightweight Concrete (CLC, or ed concrete) is a mixture of cement or cement and aggregates with a multitude of micro/macroscopic discrete air cells uniformly distributed throughout the mixture.
#0183;#32;The plight of South Africas embattled cement producers is a tale of two fortunes: better prospects in the rest of Africa and an uphill battle at home. The cement industry is operating below capacity, grappling with a tough operating environment and cheap imports from China and Vietnam as financiallysqueezed consumers are driving up demand for cheap blended alternatives to regular cement.
Higherups in South Africas cement industry testifying before the competition commission have admitted to over 10 years of collusion, implicating major international companies.

A concrete mix ratio is usually expressed by a set of numbers separated by colons, as is the case with a 1:2:3 ratio. This tells the mixer that they need to add 1 part cement powder, 2 parts sand, and 3 parts aggregate in order to create the desired concrete consistency.
Your water/cement ratio is high strength concrete design should include the slump allowance. The chapter on highperformance concrete says that the best cements to use for (highperformance concrete) for South African conditions, are CEM1 42,5R, 52,5N, 52,5R. From a table in another chapter,
