Foam Concrete -Materials, Properties, Advantages and ...

Foam concrete can be defined as a cementitious material that consists of minimum 20 percent of foam, that is mechanically entrained into the plastic mortar. The dry density of foamed concrete may vary from 300 to 1600 kg/m3. The compressive strength of foam concrete determined at 28 days, ranges from 0.2 to 10N/mm 2 or can go higher.

Polyethylene Under Concrete Slabs - GreenBuildingAdvisor

04/07/2014  Placing poly under the rigid foam runs the risk of the concrete while being placed will find its way below the rigid foam thru cracks and joints. Once this happens the foam becomes buoyant and pokes up thru the concrete like icebergs. It doesn't happen all the time, but the times I have seen it happen it was nothing less than a horror show. I just won't take that risk. Although the rigid foam ...

The weight of concrete varies but 150 pounds per cubic foot is a common approximation. Then a square foot of concrete, half a foot thick, should weigh about 75 pounds. That leaves at least 3500 pounds of weight carrying capacity before the foam below the concrete would fail. The weight of a vehicle sits on the contact patch of its tires. If we ...

Polyethylene Under Concrete Slabs - GreenBuildingAdvisor

04/07/2014  Alain - Poly on top is best The other potential issue with polyethylene at the bottom of the sandwich below the rigid foam is that the rigid foam can trap water between the poly and rigid foam.

Concrete foam fill : interestingasfuck

Of course it does, it just takes 300 million years. The real issue is that half the dopes out there using this end up pumping too much and cracking the foundation.
