High Strength Concrete Mix Proportions

High strength concrete mixes ratio m50 to m70 grade concrete mix ratio is manual designed e g m70 the quantity of cement sand fine aggregate and coarse aggregate are batched in volume as per the design mix.
High strength concrete mix proportions. Mix the ingredients for another 5 minutes and then you are done. Allow the concrete to sit for 3 minutes after this initial mixing so that the water has a chance to penetrate all of the ingredients. The strength of this mix ratio is good for most concrete slabs footings steps and foundation walls. Concrete strength measured using concrete cubes produce a results different than concrete cylinders.
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. In this type of mix this nominal concrete mix ratios and concrete constituent proportions are prefixed and specified. The type of concrete generally with compressive strength of 6000psi 40mpa or greater is called as hsc we need high strength concrete in our modern infrastructures in order to put the concrete into service at much earlier stage to build up high rise building by reducing column sizes and increasing available space or in case of long span bridges.
