unit of compressive strength of concrete

What is the meaning of a 40 MPa compressive strength Pa is Pascals the units of Pressure force per unit area so it's describing the compressive strength of a material not the strength of a structure One Pascal is one Newton force per square metre One kilogram kg needs approx 10 Newtons force to support it -unit of compressive strength of concrete-,Source CIVIL ENGINEERING FORMULAS CHAPTER 5 w/c ratio by weight and the compressive strength of concrete Ratios for non-air-entrained concrete vary between 0 41 for w c w m w c CONCRETE FORMULAS c lb/in2 in USCS units CONCRETE FORMULAS Downloaded from Digital Engineering Library McGraw-Hill lime kiln manufacturer digitalengineeringlibrary com …… Get More
