Effect of age on concrete strength: Concrete attains strength with time. Ordinary cement concrete gains above 70 to 75% of its final strength within 28 days and about 90 to 95 % in the course of one year. It is often desirable to check the suitability of a concrete …
The most basic test done on concrete in most laboratories is the compressive strength test. Sometimes other properties of concrete such as tensile strength, modulus of elasticity, shrinkage values, etc are needed for design purposes. Researchers and Standards have come up with different relationships between thecompressive strength of concrete …

Apr 13, 2011· The tensile strength of concrete is used in combined-stress design. In normal-weight, normal-density concrete the tensile strength can be found from. Advertisements. More Entries : Is it desirable to use concrete of very high strength i.e. exceeding 60MPa? What are the potential problems associated with such high strength concrete?
Uniaxial Tensile Test: This is a direct tension test in which a concrete specimen is held at the ends and pulled apart, inducing uniaxial tensile stress in it. uniaxial tensile test id one of the difficult and complicated tests to perfume on concrete but gives the true tensile strength of concrete.
Concrete and other cementitious products traditionally have very high compressive strength and much lower tensile strength. The rule of thumb is that portland cement concrete has a tensile strength that's about 10% of the compressive strength, but that percentage varies based on the mix design.
The ability of the concrete withstand in pulling force (Tensile Stress) without broke is called Tensile Strength of concrete. The tensile strength of concrete is measured by the units of Force per Cross Sectional area (N/Sqmm or Mpa). The concrete...
The flexural strength of concrete was found to be 8 to 11% of the compressive strength of concrete of higher strength concrete of the order of 25 MPa (250 kg/cm 2) and 9 to 12.8% for concrete of strength less than 25 MPa (250 kg/cm 2) see Table 13.1: . The ratio of flexural strength to compressive strength was found higher for 40 mm maximum size aggregate than that of 20 mm max sized aggregate.
Compressive Strength The main measure of the structural quality of concrete is its compressive strength. This property of concrete is commonly considered in structural design. Depending on the mix (especially the water-cement ratio) and time and quality of the curing, compressive strength of concrete can be obtained up to 14,000 psi or more. Commercial production of concrete with ordinary ...
Dec 09, 2019· Tensile strength of concrete. The tensile strength of a material is simply the measurement of the force required to pull something to the point that it breaks. In other words, you could say that the tensile strength of a material is the maximum tension it can withstand without breaking.
