Reinforced Concrete Design Civil Engineering

The allowable stresses are fractions of the crushing strength of concrete (fc') and the yield strength (fy). Because of the differences in realism and reliability over the past several decades, the strength design method has displaced the older stress design method. Limit state design. It is a further step in the strength design method.

Quality Concrete Slab Design gpsinformation.org

The concrete mix can make or break a slab floor. If the concrete is too stiff, it is hard to work into a smooth flat surface. If the mix is too wet, it is easy to work, but it shrinks a great deal more when it dries and cracks much more extensively. A good compromise is 3500 to 4000psi, maximum 3 inch slump mix.
