What is the difference between leAn concrete and ready mix concrete?
Lean mix concrete is used for substructures like foundations,piles,etc.,Ready mix concrete is used for superstructures and also for mass construction.Generally, quality of ready mix concrete is good when compared to the lean mix concrete.Workability of lean mix concrete is high when compared to RMC.
Why water is added to the concrete mix?
Water is added to concrete mux because without it, the mix could not stay moist long enough for it to get spread and leveled. <><><> Adding water starts a chemical reaction when the concrete CURES (not dries) into a solid mass. No water, your mix sits there as a dusty mix of sand, aggregate, and Portland Cement. Too much water, and your finished concrete will be of low strength.
How do you concrete mix?
Concrete mix is made from (sharp)sand, cement, aggregate and water. The ratios depent on the usage

How is concrete and mortar made?

Why is strength of concrete so important in construction?
The strength of concrete depends on the mix used to make it- ratio of cement, sand, gravel and water. If the mix does not produce a concrete that is strong enough, the concrete will break.
What is concrete mix design?
Its the process of selecting suitable ingredients of concrete and determining their relative amounts with the objective of producing a concrete of the required, strength, durability, and workability as economically as possible, is termed the concrete mix design.
What is Most important component to determine the strength of a concrete mix?
The concrete mix should be a 5:1 Cement to water ratio. make sure you mix thoroughly when adding water. Look up "Concrete slump test"
What is the percentage of admixture in concrete?
That depends on exactly what use that particular concrete mix is for.
Concrete mixing proportion for M 40 concrete?
The mix proportion for M40 concrete is 1:1.65:2.92W/C ratio = 0.4The design calculation is as per IS mix design
