Compressive Strength Of Concrete Cylinders By
All cylinders were cast and cured from four cubic yards of concrete that was delivered from a ready mix plant in lincoln. the concrete that was used in this research was class 47b with a design strength of psi at 28 days. all cylinders were tested at 28 days. materials used in preparation of concrete cylinders sulphur capping compounds.Apr 01, the crushing of concrete cubes or cylinder samples is required in a construction especially concrete structures. the reason why this is to verify the strength given in the design mix. let say for example for a concrete column commonly it has 60 megapascals of specified strength. when you crush it, the result should be equal or more than 60.
