What is Compressive Strength of Concrete Overall Strength of a structure like flexural resistance and abrasion directly depends on the compressive strength of concrete According to Wikipedia, the Compressive Strength of cement is defined as size concrete cubes tested in 28 days’ strength Why do we test concrete cubes at 7, 14 & 28 days?Specifying concrete strength is normally done with a minimum compressive strength (psi) at a certain age (days) Specified concrete compressive strength is the minimum compressive strength at which the concrete should fail in standard tests of 28dayold concrete cylinders A typical concrete compressive strength specification requires 4,000 tohow to plot a graph concrete strength vs age

24 Hardened concrete 241 Compressive strength Compressive strength tests were conducted on cured cube specimen at 7, 28 and 56 days age using a compression testing machine of 200 tons capacity The cubes were fitted at centre in compression testing machine and a very small load was applied to keep the cube in pressive strength as per American Codes In case of American codes, compression strength is defined in terms of cylinder strength fc’ Here compressive strength of concrete at 28 days curing is obtained from a standard cylindrical specimen 150mm diameter and 300mm high loaded longitudinally to failure under uniaxial compression pressive Strength of Concrete & Concrete Cubes |

The Estimation of Compressive Strength of Normal and Recycled Aggregate Concrete 423 24 Aggregate In concrete technology, the relationship between watercement ratio and strength is overemphasized The influence of aggregate on concrete strength is not generally appreciatedage is also a factor in the relation between f t and fc´: beyond about one month, Airentrainment affects the ft/fc´ ratio because the pressure of air lowers the compressive strength of concrete more than the tensile strength, particularly in the case of rich and strong mixesRelation Between Compressive and Tensile Strength of

From the graph, one can see it forms a hyperbola shape As water to cement ratio is increasing its compressive strength is gradually lacking behind Water to Cement Ratio Formulas Duff Abrams in 1919 presented an equation that relates strength of concrete with water to cement ratio Where; W/c is the water to cement ratio in the concrete mixgrade of concrete were plotted for establishing relation between UPV and compressive strength The linear regression was applied to establish the UPVstrength relationship Fig 2, Fig 3 and Fig 4 shows the relationships between UPV and strength at the age of 28 days of concrete having M15, M20 and M35 grades of concrete respectivelyrelation between compressive strength age of concrete

The concept was developed by famed American researcher Duff A Abrams in 1918 – you may know him from such classic inventions as the slump test for measuring the consistency of fresh concrete – and lays the ground rules in the relationship between the water/cement ratio and hardened concrete’s compressive strength
