Beam Bearing on Concrete  B G Structural Engineering
Beam Bearing on Concrete. Last Revised: 06/16/2011. ... The bearing plate is necessary to avoid crushing of the weaker material and to distribute the reaction force over a sufficient length of beam to prevent web yielding or crippling.
Properties of concrete  Wikipedia
Concrete tests can measure the "plastic" (unhydrated) properties of concrete prior to, and during placement. As these properties affect the hardened compressive strength and durability of concrete (resistance to freezethaw), the properties of workability (slump/flow), temperature, density and age are monitored to ensure the production and ...
Compressive strength  Wikipedia
The compressive strength of concrete is given in terms of the characteristic compressive strength of 150 mm size cubes tested at 28 days (fck). The characteristic strength is defined as the strength of the concrete below which not more than 5% of the test results are expected to fall.
