Compressive strength of concrete conclusion

Jul 24, 2017 9.0 CONCLUSION In a conclusion, the compressive strength depends on the surface area of a brick. In this experiment, it is found that the smaller the surface area, the higher the compressive strength is. 10.0 REFERENCES Kharat, R. (2013). Determine compressive strength of three different types of bricks

    Feb 13, 2015 The compressive strength is measured by breaking cylindrical concrete specimens in a compression-testing machine. The compressive strength is calculated from the failure load divided by the cross-sectional area resisting the load and reported in units of pound-force per square inch (psi) in US Customary units or megapascals (MPa) in SI units
