The compressive strength of the concrete cylinder is one of the most common performance measures performed by the engineers in the structural design Here the compressive strength of concrete cylinders is determined by applying continuous load over the cylinder until failure occurs The test is conducted on a compressiontesting machine...

Effect of Rate of Loading on Compressive Strength of Concrete Saurah Mali Tushar Pachpande and Ashwini Jogi Kothrud Pune India ABSTRACT To accurately predict the behavior of a reinforced concrete structure subjected to dynamic loads effect of change in rate ofFurther Details
Find the most uptodate version of ASTM E447 at Engineering360 Standard Test Method for Compressive Strength of Cylindrical Concrete Specimens This test method covers determination of compressive strength of cylindrical concrete specimens such as molded cylinders and drilled cores It is limited to concrete having a density in excessFurther Details
Compressive Strength The main measure of the structural quality of concrete is its compressive strength This property of concrete is commonly considered in structural design Depending on the mix especially the watercement ratio and time and quality of the curing compressive strength of concrete can be obtained up to 14000 psi or more Commercial production of concrete with ordinaryFurther Details
For concrete with a compressive strength of 3000 psi the corresponding calculated tensile strengths using these four approximations are 300 367 219 and 478 psi respectively The type of coarse aggregate in the concrete also significantly affects the compressivetensile strength relationshipFurther Details
Concrete strength measured using concrete cubes produce a results different than concrete cylinders Conservative estimates put concrete cylinders at 80 of concrete cubes for highstrengthFurther Details
Based on information reported in American Concrete Institute ACI 2281 as well as in other codes and specifications the concrete compressive strength is approximately proportional to compression wave velocity to the 4th power This means if σ is the concrete strengthFurther Details
The compressive strength of concrete is about 4000 psiFurther Details
cube size is 150x150x150 because it has been set as standard size the value of compressive strength of which has been standardized at 28 can also use 200mm cube but you have to convert the compressive strength of 200mm cube to the equivalent of 150mm cube to know the actual strength of the concreteFurther Details
A Section 261261 of ACI 31819 states that if any strength test of standardcured cylinders falls below the specified compressive strength by more than the limit allowed for acceptance or if tests of fieldcured cylinders indicate deficiencies in protection and curing steps shall be taken to ensure that structural adequacy of theFurther Details
