The mix design of concrete is determined by using IS 10262 and IS 456 codes as per the Indian conditions. In order to calculate the mix design of concrete specimens we required material properties like specific gravity, fineness modulus, fineness, initial and final setting times, grading of aggregates, water absorption etc. Example cement, fine aggregates, coarse aggregates and water. Mix design is the process of determining the proportions of materials used to make concrete. The below specified steps involves the making the cube specimen in the compressive strength testing. The preparation of test specimens is the process of making concrete cube from mix design calculation to curing period process. Testing the compressive strength using UTM.The complete compressive strength of concrete specimens is determined by using below specified three stages Process of determination of compressive strength of concrete Where P = Maximum applied load on cube specimen.Ī= Cross sectional area of cube specimen. The c ompressive strength of concrete cube is determined by using below formulae The strength is generally determined at the age of 3 days, 7 days, 14days, 28days, 56days, 90day and 180 days curing periods. The compressive strength of concrete is generally determined by using universal testing machine (UTM) in the laboratory for the cube specimens. It is the ability of the structural elements that will carry the load without any cracks or deflections. The compressive strength of the concrete is the important parameter as per the design requirements in structures. What compressive strength of concrete?
