What are Different Tests for Concrete Quality Check?
Quality tests on concrete are performed as a part of quality control of concrete structures. Different quality tests on concrete such as compressive strength tests, slump tests, permeability tests etc.are used to assure the quality of the concrete that is supplied ...
Water Quality Tests for Concrete Construction and Recommended Limits
There are various tests on water to check its quality for suitability of concrete construction. These tests on water for concrete construction is discussed. Quality of water for construction use is determined in the laboratory. This test is done as per ...
Permeability Test for Concrete Cover to Reinforcement
The durability of concrete structures depends on the permeability of reinforcement cover by concrete. It is this thin layer of concrete over reinforcement on which life of a structure depends. The permeability tester for concrete cover is a non-destructive instrument ...
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 ...
U Box Test on Self Compacting Concrete for Filling Ability of Concrete
U Box Test Method for Self Compacting Concrete U box test was developed by the Technology Research Centre of the Taisei Corporation in Japan. Some time the apparatus is called a “box shaped” test. U Box test is used to ...
