Concrete Testing Equipment

Concrete tensile strength test (Brazilian test)

This test in order to determine the indirect single axis tensile strength of a cylindrical concrete samples which is known as the Brazilian test In fact. A tensile stress is applied on concrete and other stress which the value is three times of the maximum tensile stress apply as Compressive In this case, single axis tensile stress the breakage of tensile will achieve.

Elasticity Modulus and Poisson's ratio test (Young's modulus)

Modulus of elasticity or Young's modulus is a method of measuring the strain rate as a function of stress. The applied stress can be compressive strength or tensile strength of concrete samples, and this represents the slope of the linear part of a stress-strain curves. The elasticity modulus of concrete is a key factor to estimate the deformation of structural elements, as well as a fundamental factor to determine the modular ratio, N, used for designing of structures which is subjected to bending, on the basis of concrete elasticity modulus which is proportional to the square root of compressive strength of ordinary concrete strength the following equation specifies to estimate the elasticity modulus of concrete.
