What is the Right Amount of Reinforcement for a Concrete ...

22/06/2006  Actually, reports Girard, ghosting (or shadowing) occurs when the reinforcement is pushed down into the concrete or the concrete is poured through the reinforcement. "This pushes the aggregate (or larger sand grains) aside and forms a trench that fills in with the finer particles of the cement paste. The result is that the physical composition of the concrete above the reinforcing is

Minimum Steel Reinforcement in Concrete and Clear Cover ...

18/02/2017  The minimum amount of steel reinforcement is defined as that for which "peak load at first concrete cracking" and "ultimate load after steel yielding" are equal. In this way, any brittle behavior is avoided as well as any localized failure, if the member is not over-reinforced. In other words, there is a reinforcement percentage range, depending on the size-scale,

Too much water results in weak, porous concrete that is prone to shrinking and cracking. Too little will give a mix that is difficult to work with. The amount of water recommended in the instructions seems to be the minimum that ...
