##### FAQ How To Calculate Compressive Strength Of Concrete ,

Know MoreFor normal concrete and HSC, the concrete compressive strength test results from cube specimens are generally higher than cylinders specimens 6 As states in BS 1881, the compressive strength of concrete gained by cylinder specimens is equal to 08 times of the compressive strength gained by cube specimens...

##### Minimum and Maximum Reinforcement Ratio in Different ,

Know MoreThe maximum reinforcement ratio is the largest steel area that can be put into concrete members like columns and beam In a reinforced concrete beam, the provision of extra reinforcement above the maximum reinforcement ratio would not be beneficial since the concrete would get crushed before the full strength of steel is used...

##### Strength of Concrete Nature, Kinds and Factors Concrete ,

Know MoreThe ratio of cylinder/cube strength depends on the level of strength of concrete and is higher for high strength concrete However for simplicity IS 516-1964 has suggested this ratio as 080 Table 141 below shows that this ratio varies from 077 to 096 in an irregular manner...
