Chat Online### Cube dimensions and strength Concrete

Cube dimensions and strength. The concrete structural code Eurocode 2 (BS EN 1992) is based on cylinder compressive strength. A relationship between the strength of 150mm diameter cylinders of 300mm length and 150mm cubes is given and is adopted by EN 206. In the UK, BS 8500 states that the compressive strength of 150mm cubes and 100mm cubes are considered equivalent. This has been

Chat Online### Relation Between The Cubic And Cylindrical Strength Of

Conservative estimates put concrete cylinders at 80% of concrete cubes, for high-strength concrete some say the percentage is near 100%. The ratio between the cube(150mm) and cylindrical sample(150×300 mm). Generally Strength of Cylinder sample= 0.8 x Strength of Cube. Example:- M20 is equivalent to C25. C25 is 1:1:3 (1 part cement, 1 part fine aggregate, and 3 parts coarse aggregate
