the compressive strength of concrete. Otherwise, the compressive strength of concrete is defined as the maximum crushing stress endured by the concrete. Purpose of this Test. Assume a slab at our site is designed to cast M25 grade of concrete, but we could not define its strength in the semi-solid state.

Crushing value test: The crushing value test was carried out by compression testing machine (CTM). The total load of 40 tones was applied at the rate of 4 ton per minute. The percentage crushing value was determined by divided the passing weight from total weight of aggregate. Slump Test: The Unsupported fresh concrete, flows to the

Procedure for Casting of Cubes and Testing. So, 100mmx100mmx100mm concrete cubes are used in place of 150mmx150mmx150mm cubes to raise the used stress to crush the concrete cubes. For normal concrete strength, the cube size of 150mmx150mmx150mm is already sufficient for the crushing strength of the machine. Cube Test: Instrument And Material.

The strength of concrete is controlled by the proportioning of cement, coarse and fine aggregates, water, and various admixtures. The ratio of the water to cement is the chief factor for determining concrete strength. The lower the water-cement ratio, the higher is the compressive strength. The capacity of concrete is reported in psi – pounds

The strength of concrete is generally measured by testing concrete cubes which are prepared from the concrete used in that particular construction. The cube strength of concrete is specifi ed by a structural engineer and is assessed by crushing concrete cubes at a specifi ed age (28 days after casting).

Compressive Strength Test Idea: 1- Concrete is poured in the mould and compacted properly to reduce the amount of voids. 2- After 24 hours, moulds are removed and test specimens are then placed in water for curing. 3- After the specified curing period [3, 7, 28, 56, or 91 days], specimens are tested by the compression testing machine.

Concrete cube test Procedure. Firstly, in a clean and dry pan, fine and coarse aggregates is taken by weight. The quantity of material taken should be enough to prepare at least 3 cubes of 150mm in size. It would be better if well-graded aggregates are used.

The crushing of concrete cubes or cylinder samples is required in a construction especially concrete structures. The reason why this is to verify the strength given in the design mix. Let say for example for a concrete column commonly it has 60 megapascals of specified strength. When you crush it, the result should be equal or more than 60 Mpa. The specified strength should be achieved at 28

Concrete compressive strength for general construction varies from 15 MPa (2200 psi) to 30 MPa (4400 psi) and higher in commercial and industrial structures. Compressive strength of concrete depends on many factors such as water-cement ratio, cement strength, quality of concrete material, quality control during the production of concrete, etc.
