Quicksand Condition – Occurrence Mechanism and Preventive Measures
Quicksand condition is the floatation of particles of cohesionless soil, like fine gravel and sand, due to vertical upward seepage flow. As sand boiling occurs, the bearing capacity and shear strength of the cohesionless soil decrease and the agitations of ...
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. Sand should ...
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. The stresses ...
Strut Test to Determine Euler’s Buckling Load of Strut
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 buckling load is a critical load ...
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 called compression ...
Determination of Elastic Modulus of Concrete in Accordance with ASTM C469
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 using formulas ...
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 ...
