There are many proprietary screeds on the market and information about these can be obtained from the manufacturer.

How to Calculate the Load Bearing of Concrete

This note reflects the specific mix you will order throughout your project. Write this number down. This is the base load-bearing strength of your concrete. If you are doing a smaller home project with no special accelerants added to your mix, your load-bearing strength per concrete yard will be 3,000 psi. This is the standard psi of a common mix.

Cast-In-Place Concrete | Cast in Situ Concrete Vs Precast

 · Previous surveys have shown that precast concrete slabs were on average 20% cheaper than the cast-in-place concrete elements and precast columns were averagely 21.4% less than cast-in-place concrete columns. Because precast concrete can be manufactured on an assembly line, each cast needs significantly less labor and hence costs less in labor.
