c30 concrete compressive strength

C30 Concrete Compressive Strength

compressive strength of concrete -cube test, procedure,concrete compressive strength for general construction varies from 15 mpa (2200 psi) to 30 mpa (4400 psi) and higher in commercial and industrial structures. compressive strength of concrete depends on many factors such as water-cement ratio, cement strength, quality of concrete material, quality control during the production of concrete, etc..factors affecting concrete performance : u/bunch19,the results show that for c30 concrete, the 28-day compressive strength of machine-made sand concrete prepared with limestone and granite is relatively close, and the difference between the two is about 5mpa; for c50 concrete, the 28-day compressive strength of limestone machine-made sand concrete is the lowest the difference of granite machine-made sand concrete is about 20mpa..
