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 to fall.
Compressive Strength of Concrete is an important element in designing R.C.C Structure R.C.C.Structures Compressive Strength of Concrete Consequently Quality of concrete manufactured is often measured by
EXPERIMENT NO: 07. TO DETERMINE THE COMPRESSIVE STREHGTH OF CEMENT MORTAR IMPORTANCE & THEORY: Cement is usually subjected to compressive stresses when used in the form of concrete or mortar.
Normal concrete was prepared with a water-cement ratio of 0.50. cube specimens were cast for testing the compressive strength at 7 and 28 days of curing respectively using three curing methods namely immersion, sprinkling and Plastic sheeting, curing to cure the cube specimens until the day of testing. Test results indicates that water curing (WAC) as well as sprinkling (spraying) curing ...
Note: If the 150 mm x 150 Concrete cube does not give you the above compressive strength of concrete so it mean that you did not fully vibrate the concrete cube therefore it can not able to give you the above Strength.

Compressive strength determined on 50mm (2 inch) cube specimens for Fine mix and 100mm (4 inch) diameter cylinders for Coarse mix In discussions with Target technical specialists, they indicate that cylinders are specified for the coarse
Compressive strength of concrete cube test provides an idea about all the characteristics of concrete. By this single test one judge that whether Concreting has been done properly or not. Concrete compressive strength for general construction varies from 15 MPa (2200 psi) to 30 MPa (4400 psi) and
2. PURPOSE OF THE TEST: Well we all know the basic purpose of the test and some other purposes of the tests are as follows: • The compressive strength of cubes gives us the information of the potential strength of the concrete mix from which it is sampled.
Testing concrete cylinders and cubes is the most widely used test for measuring the compressive strength. For example, ASTM C 39 provides a standard procedure for testing concrete cylinders and reporting the test results.

5. Weighing balance. Specimen For Test: The cube samples shall be of 15 x 15 x 15 cm. If the largest nominal size of the aggregate does not exceed 2 cm, then cube …
By this single test one judge that whether Concreting has been done properly or not. Concrete compressive strength for general construction varies from 15 MPa (2200 psi) to 30 MPa (4400 psi) and higher in commercial and industrial structures.
What is the Compressive strength? Compressive strength is the capacity of material or structure to resist or withstand under compression. The Compressive strength of a material is determined by the ability of the material to resist failure in the form cracks and fissure.

Factors Affecting Strength Test Results of Concrete. Compressive strength is the most important property of concrete. The compressive strength of concrete is determined in the laboratory in controlled conditions.
The compressive strength of concrete is the most common performance measure used by the engineer in designing buildings and other structures. The compressive strength is measured by breaking cylin-drical concrete specimens in a compression-testing machine. The compressive strength is calculated from the failure load divided by the cross-sectional area resisting the load and …
