To make 1 cubic metre of 30 Mpa concrete you will need to mix 10 bags of cement with 0,65 cubic metres of sand and 0,65 cubic metres of stone. Small Batches of Concrete Mixes. Your water/cement ratio is critical.Any high strength concrete design should include the "slump" allowance. This is the amount that concrete placed in a cylinder

The pH of fresh cement is enough to prevent reinforcing steel from oxidizing (rusting). If, however, cracks allow corrosive elements in water
201668&ensp·&enspConcrete mix design is the process of finding the proportions of concrete mix in terms of ratios of cement, sand and coarse aggregates. For e.g., a concrete mix of proportions 1:2:4 means that cement, fine and coarse aggregate are in the ratio 1:2:4 or the mix contains one part of cement, two parts of fine aggregate and four parts of coarse aggregate.

What Are the Different Grades of Concrete? The strength is measured in psi, or pounds per square inch. The greater the psi rating on a mix of concrete, the stronger the concrete will be after it has been poured and set. Any type of concrete that is rated higher than 6,000 psi is considered to be highperformance concrete. This grade is
