Compressive strength is measured by breaking cylindrical concrete specimens in a compressiontesting machine. Compressive strength is calculated from the failure load divided by the crosssectional area resisting the load and reported in units of poundforce per square inch (psi) or megapascals (MPa).

Portland Cement Compressive Strength. The most common strength test, compressive strength, is carried out on a 50 mm (2inch) test specimen. The test specimen is subjected to a compressive load (usually from a hydraulic machine) until failure. This loading sequence must take no less than 20 seconds and no more than 80 seconds.

Determine the mass of the cylinder and record it. This information is useful in troubleshooting low strength problems. Caps on cylinders must be flat and the average thickness less than 1/4inch (6mm) and preferably less than 1/8inch (3 mm). This is especially significant when testing concrete with strength exceeding 7000 psi (48 MPa).

### COMPRESSIVE STRENGTH OF CONCRETE CUBES

For cube test two types of specimens either cubes of 15 cm X 15 cm X 15 cm or 10cm X 10 cm x 10 cm depending upon the size of aggregate are used. For most of the works cubical moulds of size 15 cm x 15cm x 15 cm are commonly used.
