Spanish and European Codes on Structural Concrete (Spanish Code on Structural Concrete, EHE, and Eurocode 2, EC2, respectively) allow measuring the concrete compressive strength with cubic specimens, normally 150 mmedged cubes, instead of the standard cylinders, which are 150 mm in diameter and 300 mm in height.

Prior to performing compressive strength tests on cylindrical concrete specimens, it's important to understand both of the most popular options for preparing the cylinder ends. Proper end preparation ensures that the ends of concrete test cylinders or cores have smooth, parallel bearing surfaces perpendicular to the applied axial load to assure uniform distribution of forces during testing.

Compression Test of the Concrete Specimen is most widely used test to measure its compressive strength. Two types of concrete specimen: Cubes Cylinders are used for this purpose: Cubes of size 150mm are more common in Asia, Russia European countries while Cylinders of 150mm in diameter 300mm high are common in and Australia.

reinforced steel bars imbedded in concrete .A total of 72 cubes were cast to determine compressive strength and 24 cylinder to determine the indirect tensile strength. Bond strength between reinforcing bars and concrete was determined by pullout test on 24 concrete blocks. Corrosion rate was studied and the results are presented.

The compressive strength of the concrete cylinder is one of the most common performance measures performed by the engineers in the structural design. Here, the compressive strength of concrete cylinders is determined by applying continuous load over the cylinder until failure occurs. The test is conducted on a compressiontesting machine.

The compressive strength of cement concrete obtained after 28 days of moist curing is used in the quality control of constructions. However, for economical quality control, for reworking before the concrete gets hardened and for reducing the waiting time, finding the 28day compressive strength at an earlier time with a reasonable accuracy is ...
