In technical terms ,if the cement content of the mix falls out to be lesser than 10 percent than the mix is called as lean concrete mix.

What is lean concrete mix and its purpose?

What is lean concrete mix and its purpose?

Concrete is a mixture of Portland cement, water and aggregate. The water/cement ratio is the determining factor of the strength of concrete. Concrete is stronger with less water in the mix. But water makes the concrete workable; the typical water/cement ratio balances strength and workability.

Too much water means too much shrinkage - and too much shrinkage leads to cracks in the finished project. This is usually a cosmetic flaw rather than a structural one. At the same time, if you want to avoid it, make sure you stick with the ratio of .5 - that means that for every pound or kilogram of cement, use half a pound or kilogram of water.

Cement powder is commonly made of lime and clay and is a key ingredient of concrete. Cement itself is produced by heating limestone with small amounts of other ingredients such as clay. The mixture is brought to a high temperature in a kiln, and the hard substance which results is referred to as “clinker.”.” Clinker is then ground up into a powder along with a small amount

Regardless, this aggregate mixture makes up to 75% percent of the volume of a concrete mixture. Crushed Stone Aggregate Other materials can be added to the concrete mixture to modify its properties.

The low water-cement quantitative relation makes this sort of cementless feasible. to combat this weakness, superplasticizers are other to the present concrete combine. Stamped Concrete Stamped concrete is a subject area concrete wherever realistic patterns almost like natural stones, granites, and tiles will be obtained by inserting the ...
