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. ...
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. ...
Strut test is used to determine the Euler's buckling load of the strut. Struts are long, slender columns that fail by buckling some time before the yield stress in compression is reached.The Euler's ...
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 ...
Modulus of elasticity of concrete is the ratio of normal stress to the corresponding strain for tensile or compressive stresses below the proportional limit of concrete, ACI 318-14. The value of elastic modulus of concrete can be obtained ...
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 ...
Hot weather has a significant effect on all stages of concrete production and placement procedures such as increasing rate of hydration and movement of moisture from within ...
Rubber balloon test method is an in-situ test conducted to determine field density of soils especially compacted soils. Apparatus required, test procedure and calculations of rubber balloon method are explained in this article.Field Density of Soil ...
