Concrete Compressive Strength slideshareTensile Strength of concrete Test Procedure

The concrete mixture is designed to produce an average strength ƒ 180 c higher than the specified strength such that the risk of not complying with the strength specification is minimized To comply with the strength requirements of a job specification both the following acceptance criteria apply 1 The average of 3 consecutive tests should equal or exceed the specified strength ƒ 180 c 2 The tensile strength of concrete is generally in the range of 10 to 12 of its compressive strength The concrete cube was used to find out the compressive strength of concrete but to find the tensile strength of concrete a cylindrical specimen has to be used

What is Compressive Strength Definition from CorrosionpediaWhat is Workability of Concrete Types Mechanism Civil

Compressive strength is a limit state of compressive stress that leads to failure in a material in the manner of ductile failure infinite theoretical yield or brittle failure rupture as the result of crack propagation or sliding along a weak plane The strength of concrete is the most important property for us It depends on density ratio or compaction and compaction depend on sufficient workability Fresh concrete must have a workability as compaction to maximum density is possible with a reasonable amount of work
