In this paper we investigate the inﬂuence of the shape and of the size of the specimens on the compressive strength of high strength concrete. We use cylinders and cubes of different sizes for performing ... and cubes. Shape ...

Compressive strength of concrete depends on many factors such as water-cement ratio, cement strength, quality of concrete material, quality control during production of concrete etc. Test for compressive strength is carried out either on cube or cylinder.

Compressive strength of concrete cube test provides an idea about all the characteristics of concrete. Cube test results judges proper concreting at site.... Online Services

Specified concrete compressive strength is the minimum compressive strength at which the concrete should fail in standard tests of 28-day-old concrete cylinders. A typical concrete compressive strength specification requires 4,000 to 5,000 psi at 28 days.

Compressive strength test, mechanical test measuring the maximum amount of compressive load a material can bear before fracturing.The test piece, usually in the form of a cube, prism, or cylinder, is compressed between the platens of a compression-testing machine by a gradually applied load.

conducted to determine the correlation between actual compressive strength of concrete cubes and strength estimated from cores having different H/D ratio (1.5, 1.75 and 2.0) and diameter of 50mm.

Compressive Strength Test on Concrete Procedure Representative samples of concrete shall be taken and used for casting cubes 15 cm x 15 cm x 15 cm or cylindrical specimens of …
