How to Calculate Rate of Loading for Concrete Cube
9/11/2019· Almost all answer it as, Sir as per IS 516 rate of loading is 140 kg / Sqcm / Minute, The load shall be applied slowly without shock and increased continuously until the resistance of specimen (concrete cube) to increasing load breaks. Superb, you absolutely know what specified in the IS Code now this is cube testing machine and this is cube.

Effect of Rate of Loading on Compressive Strength of Concrete
testing of concrete in compression with methods used for recordings and testing stress and strain. The data recorded by them show and indicate the various types of loading rate that will be applied on concrete under various conditions. They also pointed out the vast range of straiun rate applied on concrete (108 under creep to 103 under blast effect). Hence studies are carried out to determine the strength of concrete

Compressive Strength of Concrete & Concrete Cubes
7/7/2016· With variation in rate of loading on concrete specimen, the strength varies proportionately. At higher rate of loading, the compressive strength increases. The increment is from 30% to almost 50% of the original strength. However, at lower rate of loading, the reduction in strength of concrete cube compared to its true strength is insignificant.
