Compressive Strength Test Of Concrete Detailed
The minimum value of Compressive Strength for a cube As per IS 456, the individual compressive value of a concrete cube should not be less than 75% of its grade Example – If the concrete grade is M20, then theGrade of concrete is denoted by prefixing M to the desired strength in MPa For example, for a grade of concrete with 20 MPa strength, it will be denoted by M20, where M stands for Mix These grade of concrete is converted into various mix proportions For example, for M20 concrete, mix proportion will be 1:15:3 for cement:sand:coarse aggregatesDifferent Grades of Concrete, Their Strength and Selection for
Compressive Strength of Concrete and Concrete Testing
The rate of loading is 06 ± 02 N/mm2/s Record the maximum force from the machine The same procedure is followed in the testing of concrete cylinders also Compressive strength can be calculated from the following equation Compressive Strength = Applied Maximum Load / Top surface area of the specimenAs per studies and researches, the compressive strength of the concrete will increase with age Most researches were conducted to study the 28thday strength of concrete But in reality, the strength at 28th day is less compared to the longterm strength that it can gain with age The concrete strength variation with age can be studied byConcrete Compressive Strength Variation with Time
