Standard Mix. The nominal concrete mix of a fixed proportion of cement, sand and aggregate provide considerable variation in strength resulting in the poor or over-rich mix. Hence minimum compressive strength has been assigned in many proportions and termed as the standard mix. As per IS 456:2000 Standard Concrete grades are M 25, M 30, M 35, M

Learn MoreConcrete mix ratio is a vital topic in concrete mix design. The four basic ingredients for making concrete are: Portland cement, sand, aggregate (stone) and water. The strength of concrete mixture depends on the ratio in which these four ingredients are mixed.

Learn MoreTypically, a mix is about 10 to 15 % cement, 60 to 75 % aggregate and 15 to 20 % water. This concrete mix ratio of aggregate to sand to cement is an important factor in determining the compressive strength of the concrete mixture.

Learn MoreThe ideal concrete mix to use for constructing a driveway should have at least a 4,000 psi compressive strength, a water-cement ratio of 0.50, aggregates no larger than 1-inch in size, and a slump thickness of 4 to 5 inches. In colder climates, the mixture should have an air-entrainment value of 6%. Driveways often are subject to the elements
