Why Concrete Delamination Occurs - and What to Do About It

The cold ground slows the setting of the bottom part of the slab, making the timing of finishing even more difficult to judge. To reduce this differential set retardation, keep the sub-grade covered until the time of concrete placement. Do warm the concrete or use small doses of set accelerator to promote a more uniform setting of the mix.

What Is The Standard Strength Of Concrete? - Big D Ready Mix

The flexural strength of concrete is usually determined by testing a simple beam where the concentrated load is applied at each of the third points. The numbers are then expressed in a Modulus of Rupture (MR) in psi. Depending on the specific concrete mix, flexural strength is ideally anywhere between 10% and 15% of the compressive strength.
