In psi show the compressive strength of foamed concrete

Aug 28, 2020

PSI is a measure of compressive strength, or the ability of the material to carry loads and handle compression. 1.) 2500-3000 PSI Most concrete has a PSI rating of 2500 to 3000. This type of concrete can be used for sidewalks and residential driveways. This concrete is generally more affordable than higher strength concrete. Need help with a

    Compressive strength is measured in PSI and refers to how many pounds one square inch of the insulation can support. Since the weight of the concrete slab is spread equally across the whole foundation, the insulation doesn’t have to be as strong as you’d think. ...
