(May 2014) ( Learn how and when to remove this template message)Compressive strength or compression strength is the capacity of a material or structure to withstand loads tending to reduce size, as opposed to tensile strength, which withstands loads tending to elongate. In other words, compressive strength resists compression (being pushed together), whereas tensile strength resists tension (being pulled apart).

However, tensilestrength of concrete is very low in compared to its compressive strength.Due to difficulty in applying uniaxial tension to a concretespecimen, the tensile strength of the concrete is determined by indirecttest methods: (1) Split Cylinder Test (2) Flexure Test.It should be noted that both of these methods give thehigher value of tensile strength than the uniaxial tensile strength.Split-Cylinder TestIt is the standard test, to determine the tensile strengthof concrete in an indirect way. In the past 40 years, many different test conditions, sometimes even completely opposite conditions have been adopted.

In order to show which conditions should be selected and uniaxial tensile test of concrete the conditions should be selected, theoretical and experimental investigation was carried out. For the experiment, prismatic specimens with notches and an originally designed gear system preventing secondary flexure were adopted. It was shown that the tension softening curves were successfully monitored by the present procedure with a high success ratio. A practical test procedure of uniaxial tension test of concrete was proposed based on the uniaxial tensile test of concrete. Please enable JavaScript to use all the features on this page.

AbstractAn overview is given of methods to determine the strength and fracture energy of concrete subjected to uniaxial tension. Strength usually gives an OverallPicture of the quality of concrete because it is directly related tothe uniaxial tensile test of concrete of cement-paste.Compression TestTensile TestCompression TestCompression Test of the Concrete Specimen is mostwidely used test to measure its compressive strength.
