compressive strength of high strength concrete We use cylinders and cubes of different sizes for performing stable stress strain tests The tests were performed at a single axial strain rate 10 161 6 s 161 1 This value was kept constant throughout the experimental program Our results show that the post peak behavior of the cubes isAs per Indian codes compressive strength of concrete is defined as The compressive strength of concrete is given in terms of the characteristic compressive strength of 150 mm size cubes tested at 28 days fck The characteristic strength is defined as the strength of the concrete below which not more than 5 of the test results are expected

In cube strength of concrete testing why only 150mm 150mm 150mm cube is used why not the mold of other dimensions are used Engineering Concrete Question added by sushma ravi Date Posted /09/25 If you want to test another size you should use a unique testing equipment another question is why bricks are in this size I think that A slump test is a method used to determine the consistency of concrete The consistency or stiffness indicates how much water has been used in the mix The stiffness of the concrete mix should be matched to the requirements for the finished product quality Slump is a measurement of concrete s workability or fluidity It s an indirect measurement of concrete
