Double Shear Test on Mild Steel

Double shear test is used to determine the shear strength (ultimate shear stress) of the mild steel specimen. Universal testing machine (UTM) is used for performing double shear test. There are two types of UTM namely: screw type and hydraulic type. ...

The penetration resistance test used for the determination of initial and final setting time of concrete mixture in laboratory and project site, and the effects of variables, such as water content; type and amount of cementitious material; or admixtures, upon the ...

Bulk Density and Void Percentage Test for Aggregates

The bulk density and void percentage of aggregate can be evaluated using standard test methods of applicable codes such as ASTM C 29/C29M-17a, IS: 2386 (Part 3) – 1963, or BS 812-2:1995. The procedure provided in this article ...

What is Proof Stress? Importance and Determination

Proof stress of a material can be defined as the stress at which the material undergoes plastic deformation. Proof stress is determined as the stress corresponding to 0.2% of strain from the stress-strain curve of the given material. ...

Safe Bearing Capacity values of Different Soils

The capacity of the soil to allow the loads coming from the foundation is called bearing capacity of the soil. The gross pressure at the base of the foundation at which soil fails is called ultimate bearing capacity. ...
