Read MoreDec 17 2019nbsp018332The ratio of aggregate to sand to cement is an essential factor in determining the compressive strength of the concrete mixture. The best mix for concrete driveways is 1 part cement. Three parts sand. Three parts aggregate will produce a concrete mix of approximately 3000 psi. By using these materials They follow these steps Mix water with the cement sand and stone which
Read MoreRecommended ratios will enable you to mix concrete to match the function for which it is intended or the strength of the concrete required. One 50 kg sack of cement has a volume of 33 litres 0033 cu m. A builders wheelbarrow filled level to the top has a volume of 65 litres 0.065 cu m which is almost double the volume of a sack
Read MoreConcrete mixing ratios are the formula for calculating the correct amount of each ingredient used including water cement sand and aggregate to produce concrete with the properties desired. A basic concrete ratio is one part cement two parts sand and three parts gravel slowly mixing in
Read MoreThe strength of concrete mixture depends on the ratio in which these four ingredients are mixed. Concrete mix ratio of 133 On mixing 1 part cement 3 parts sand with 3 parts aggregate produces concrete with a compressive strength of 3000 psi

While it may be prudent for legal reasons to specify a minimum strength it is just as well as to develop the mix design for slabonground applications by specifying the maximum sack content water
Read MoreConcrete mix design is the process of detrmining right proportions of cement sand and aggregates for concrete to achieve target strength of concrete. The Advantages of concrete mix design is that it gives the right proportions of materials thus making the concrete use economical in achieving required strength of structural members
Read MoreThe main object of mixing concrete cement sand coarse aggregates and water is to obtain a uniform and easily workable concrete paste.
