A Simple Guide to Concrete Cube Testing QEM
Before the concrete is scooped into the moulds, the moulds must be lightly coated in a mould release agent. This ensures that the concrete does not stick to the mould and makes it easier to remove the cube. When using a 150mm mould, the concrete sample is scooped into the mould in 3 equal layers (50mm) and compacted between each layer.

Beam Bearing on Concrete B G Structural Engineering
Beam Bearing on Concrete. Last Revised: 06/16/2011. A bearing plate takes the reaction of a steel beam and distributes that force over a larger area that is made of a material that is not as strong as steel. The action is essentially the same as a footing that distributes a large load to softer soil.

Aug 07, 2010 · Figures 1.24 and 1.25 show examples of side and tension face plated beams in which concrete crushing occurred prior to debonding of the plates. Small amounts of IC interface cracking can be seen along the edges of the plates but this was not sufficient to reduce the stresses in the plates so that the beams achieved their theoretical flexural capacities based on the material properties.

Size Effect in Flexure of Prestressed Concrete Beams
In unprestressed reinforced concrete beams, the design code (ACI Committee 318 2008) requires the steel ratio to be less than 75% of the balanced steel ratio, in order to ensure the beam to fail by the yielding of steel rather than by the crushing of concrete. Therefore, in such beams, termed underreinforced, there can be no size deter

Enhancement of RC Beams by Textile Reinforced Concrete (TRC
Debonding of textile reinforced strengthening layer occur at the bottom of the beam but the failure of beams strengthened by one and three layers of fabric in bottom face due to the rupture of the textile fabric and the final failure of beam is by crushing of concrete at the compression face in both RC strengthened beams.

Strengthening of reinforced concrete beams by using fiber
Therefore, the concrete cover and bond between concrete and NSM strips control failure mode. Moreover, ductile side NSMstrengthened beams fail in concrete crushing through intermediate crackinduced debonding rather than through concrete cover separation . The smooth surfaces of NSM strips can reduce adhesion between the strip and adhesives.

Jul 22, 2009 · As the concrete is compressed in one direction, it wants to spread in the orthogonal direction, but can''t because of the restraining surrounds. I disagree with AHaddad1 that it is related to "shear cone" failure. Bearing failure in concrete should be thought of as a crushing failure, while shear failure is a diagonal tension failure.
