Concrete Compressive Strength Chart

characteristic strength of concrete - engineering discoveries,the classification of concrete grades is based on their compressive strength. each concrete grade e.g. c30/37 is characterized by two equivalent strengths, which in.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..
