Test for Silt Content in Sand

Sand or fine aggregate is one of the most important construction materials at any construction site. Its selection should be done very carefully as it contributes to the strength of various important mixtures like concrete, plasters and mortar. ...

Stress-strain Curve for Steel Bars

The stress-strain curve describes the behavior of steel bars under loads. It is created by testing steel specimens. A steel specimen is gradually pulled through a testing machine until it breaks, and stress and corresponding strains are recorded. ...

Test to Determine Modulus of Elasticity of Concrete

Modulus of elasticity of concrete is defined as the ratio of stress applied on the concrete to the respective strain caused. The accurate value of modulus of elasticity of concrete can be determined by conducting a laboratory test ...

Tension Test on Steel Rod – Procedure and Results

Tension test is performed on mild steel, tor steel and high tensile steel to determine the properties like Young's modulus, ultimate strength, and the percentage elongation. In the tension test, a steel rod is subjected to tension load by the ...
