Methods of Proportioning Cement, Sand and Aggregates in Concrete
Proportioning of concrete is the process of selecting quantity of cement, sand, coarse aggregate and water in concrete to obtain desired strength and quality. The proportions of coarse aggregate, cement and water should be such that the resulting concrete has the ...
BEHAVIOUR OF CONCRETE UNDER TENSION
Concrete is not normally designed to resist direct tension. However, tensile stresses develops in concrete members as a result of flexure, shrinkage and temperature changes. Principal tensile stresses may also result from multi-axial states of stress. Normally cracking in concrete ...
Determination of Bulk Density of Concrete as per IS-1199
Bulk density of concrete is the mass of freshly mixed concrete required to fill the container of a unit volume. Bulk density of concrete reflects the ability of concrete to function for structural support, water and solute movement, and durability. This method helps ...
