compressive strength of foam concrete

EPS foam density for use under concrete slabs and around

Its compressive strength is similar to sandy soil. A 4" slab contributes about 50 psf of load; add a 40lb live load and you're still below 1 pound per square inch. The compression curve for foam plastic is usually pretty straight, so insulation rated at 15 psi would compress somewhere in the neighborhood of 0.015 of its thickness.

Compressive Strength | EPS Industry Alliance

Compressive Strength. EPS is a closed cell, lightweight and resilient, foamed plastic composed of hydrogen and carbon atoms. The mechanical strength of EPS varies with its density. The most important mechanical property of EPS insulation and building products is its resistance to compressive stresses, which increase as the density becomes higher.

HIGH-STRENGTH STRUCTURAL LIGHTWEIGHT CONCRETE

Conventional cellular concrete produced with a pre-formed foam mixture is produced by discharging a stream of preformed foam into a mixing unit on site or a transit mix load of sand-cement grout or cement-water slurry. This foam [surfactant] resembles shaving cream or the foam used for firefighting.

Modelling the compressive strength and thermal properties of foam concrete

Foam concrete has attracted attention worldwide because of its light weight and enhanced insulating properties as a building material. Pore features in foam concrete play an important role in affecting its compressive strength and insulation properties. Therefore, quantitative description of relationships between pore features heat conductivity and compressive strength is the main
