Segregation of concrete is the separation of cement paste and aggregates of concrete from each other during handling and placement. Segregation also occurs due to over-vibration or compaction of concrete, in which cement paste comes to the top ...
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 ...
Concrete is known to be a very versatile and reliable material, but some construction errors and construction negligence can lead to the development of defects in a concrete structure. These defects in concrete structures can be due to ...
A point about which a floating body tries to oscillate is called the metacenter of that body. The distance between metacenter (M) and the center of gravity (G) of the floating body is known as metacentric height (GM).
Covermeter test is a nondestructive test which is used to specify the location of reinforcement bars in concrete and determine the exact concrete cover needed. The magnetic rebar locator test plays a significant role in construction works because ...
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 ...
Strengthening of existing reinforced concrete walls becomes necessary either when they lose their strength and capacity to take up the stipulated loads or when you need to increase their load carrying capacity. This kind of rehabilitation is mostly ...
A proper understanding of the transfer of stresses(generated due to applied loads) from columns to the footings or piles is crucial for the design of sound footings. Factored forces and moments at the base of columns are transferred to the ...
