How Do You Calculate PSI Strength Of Concrete?
Concrete is a unique material in that it is very strong in compression, but extremely weak in tension. Cracks in some concrete surfaces occur not directly from compressive forces, but tensile forces that occur when the surface deforms slightly. However, concrete structures depend on concrete’s compressive strength, and it is necessary to experimentally test the strength of any particular concrete mixture. The most common test of compressive strength is the cylinder test. Note the characteristics of your concrete mixture. You should note what percentage of the mixture is course aggregate, fine aggregate and cement. You may also want to perform a slump test, which involves compacting wet concrete into a cone and measuring how many inches it slumps when removed. This indicates how firm or runny the mixture is. Create a cylinder out of the wet concrete using a mold. The cylinder should be twice the height of its diameter, preferably with dimensions around 12 and 6 inches. Small cylinders c
