The PCC concrete ratio 1:3:6 indicates the proportions of cement, sand and aggregate used in the nominal concrete mix. The numbers indicate the parts of each material based on volumetric analysis. For example, in a 1:3:6 concrete mix ratio, 1 part of cement mixed to 3 parts sand and 6 parts of aggregate by volume.
Mix Ratio Table for Standard Mix Concrete. The mixtures of grades M10, M15, M20, and M25 are roughly equivalent in mixing ratios (1:3:6), (1:2:4), (1:1.5:3), and (1:1:2), respectively. The Tanned Mix Ratio Specifications for Concrete stipulated these ratios of cement, sand, aggregate, and water.
This is a free online tool by EverydayCalculation.com to calculate material consumption for a concrete structure i.e., quantity of cement, sand, stone gravel required in different concrete ratios.
Concrete mix ratios are the proportions of concrete components such as cement, sand, aggregates and water. These mix ratios are decided based on mix design.
Calculate cement concrete mix design or estimate how much cement concrete volume is required for your construction using our free online calculator. Know exactly how many bags, kg and ton of cement, sand and aggregate is needed of specific cement, sand and aggregate ratio (m20, m15, m10, m7.5)
The mix design of concrete takes into account various factors such as the compressive strength required, the type and size of aggregates, the water-cement ratio, the shape of coarse aggregates, the workability needed, the exposure conditions, and the type of cement used.
The design of concrete mixtures involves the following: (1) the establishment of specific concrete characteristics, and (2) the selection of proportions of available materials to produce concrete of required properties, with the greatest economy.
