the resistance of concrete to crushing
Properties of concrete Wikipedia . In very high strength concrete mixtures greater than 70 MPa the crushing strength of the aggregate can be a limiting factor to the ultimate compressive strength In lean concretes with a high water cement ratio the crushing strength of the aggregates is not so significant The internal forces in common shapes of structure such as arches

01/04/2018Commonly, it has 60 mega pascals of specified strength. When you crush concrete cubes, the result should be equal to or more than 60 Mpa. The specified strength should be achieved at a test age of 28 days but sometimes we experience failure results at 28 days. That''s the reason we have spare cubes or cylinder samples.

A better performance was observed, using alkaliactivated flywheel and lime, corresponding to approximately 5 MPa at seven days of curing and 9 MPa at 28 days, in contrast to 1 MPa obtained as Portland cement and additives. The technique of soil stabilization has undoubtedly been widespread in the geotechnical engineering literature for years.
