What Next If Concrete Cubes Failed After 28 Days

The failure result of a concrete cube is a serious issue you need to analyze why the cubes have failed by finding out a proper reason for failure we may avoid further reoccurrences of the same concrete cubes failed after 28 days when we are doing concreting on site and collecting sample for the test there are four possible combinations

Concrete Bearing Structural Engineering General

Jul 22 2009 as the concrete is compressed in one direction it wants to spread in the orthogonal direction but cant because of the restraining surrounds i disagree with ahaddad1 that it is related to shear cone failure bearing failure in concrete should be thought of as a crushing failure while shear failure is a diagonal tension failure
