C2025 Concrete Strength In Psi

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..rosendale cement performance,compressive strength. minimum 1020 psi (7 mpa) @ 28 days (1:1 with test sand) lower initial strength than portland cement, comparable strength to lime/portland blends and hydraulic lime. modulus of elasticity. typically 535,000-640,000 psi lower than stone, brick, portland cement (see chart, right) modulus of rupture. typically 400-600;.
