Concrete has almost no tensile strength usually measured to be about 10 to 15% of its compressive strength and for this reason it is almost never used without some form of reinforcing Its compressive strength depends upon many factors including the quality and proportions of the ingredients and the curing environment

The compressive strength of concrete is the most common performance measure used by the engineer in designing buildings and other structures The compressive strength is measured by breaking cylin-drical concrete specimens in a compression-testing machine The compressive strength is calculated from the failure load

As the porosity increases the compressive strength of the concrete decreases STRENGTH OF CEMENT V/S STRENGTH OF CONCRETE It is not possible to design a concrete mix of high strength with cement of low strength

Fresh concrete Concrete mixed while it can still be worked and compacted Hardened concrete Concrete when set with measurable strength Green concrete Newly placed and compacted stable before the start of detectable setting green concrete is a pre-casting industry term

concrete having the compressive strength class of C25/30 at the age of 28 days mix cured and the compressive strength is determined on cubes with the sizes of 150 mm will have a mean compressive strength instead of the above calculated f
