Tensile Test on Concrete

However tensile strength of concrete is very low in compared to its compressive strength Due to difficulty in applying uniaxial tension to a concrete specimen the tensile strength of the concrete is determined by indirect test methods (1) Split Cylinder Test (2) Flexure Test Strength of concrete was determined by testing Using ANN the multi-dimensional six acceleration readings were given as input and the same mapped to a single output of concrete strength The range of acceleration values varied from 0 7 m/s 2 to 136 4 m/s 2 and compressive strength from 16 to 43 56 MPa

WHAT ARE THE FACTORS INFLUENCING COMPRESSIVE STRENGTH TEST

Compressive strength is the most important property of concrete The compressive strength of concrete is determined in the laboratory in controlled conditions On the basis of this test result we judge the quality of concrete But sometimes the strength test results vary so widely that it becomes difficult to reach at any conclusion This variation in test results can be avoided by taking necessary steps The theoretical maximum compressive strength of a cylinder can be calculated by Some common values needed for failure are Beam - 20MN/m 2 (3000 psi) Cylinder - 35 MN/m 2 (5000 psi) The experiment could be used to show the development of strength over time
