Compressive strength of Concrete Core specimen IS 516-1959

compressive strength of concrete core

Concrete core Test  standard: IS 516:1959 Compressive Strength Definition: Compressive strength is the ability of material or structure to carry the loads on its surface without any crack or deflection. A material under compression tends to reduce the size, while in tension, size elongates.   Objective:   To determine the compressive strength of concrete cores, …

How to find fresh wet density and Yield of concrete IS 1199-1959

wet density of fresh concrete

Why need to findout fresh wet density and Yield of concrete? Wet density of concrete reflects the ability of concrete to function for structural support, water and solute movement, and durability. This method helps to calculate the yield of concrete per cubic meter. Test apparatus : Weighing balance of accuracy 10gms. Tamping steel bar of …

Determination of Initial and final setting time of concrete by penetrometer Is 1842-1976

penetration resistance appratus

penetration resistance appratus Why we conduct the Concrete Setting Time Test? It is essential that cement set neither too rapidly nor too slowly. In the first case there might be insufficient time to transport and place the concrete before it becomes too rigid. In the second case too long a setting period tends to slow …

Tensile strength Test of Rebar Coupler |IS 1608

Tensile strength Test of Rebar Coupler

Tensile strength Test of Rebar Coupler The tensile strength test of rebar coupler carried out in accordance with IS 1608. A tensile test on an un-spliced specimen from the same bar used for the preparation of spliced specimen shall be performed to establish the actual tensile strength of the reinforcing bar. For the calculation of …
