Mar 01, 1995 · A.: The R-value of an uninsulated, 8-inch-thick basement wall built using normal-weight concrete is 1.35, based on data from the 1993 American Society of Heating, Refrigeration, and Air-Conditioning Engineers' Handbook. By doubling the thickness of the wall to 16 inches, the R-value only increases by 0.50

It's made by mixing ground styrofoam with concrete. It can be made light enough to float on water. For fine detail, use the finest grade sand you can find, and add a plasticizer (Kongcrete) and fly-ash for workability. You can increase the detail by spraying a face coat with straight concrete, then filling the rest of the volume with EPSCrete

An 8″ hollow concrete block (the type used for most concrete block walls) only has an R-Value of 1.11. EPS insulation blocks that are 5” thick have an R-value of R-20.5. Simply by placing the EPS blocks inside the concrete block voids while the foundation wall is being built, that R-1.11 insulation value for the block wall is turned into an

EPS (Styrofoam) has been used in concrete. New EPS beads are currently sold as concrete aggregate, and several universities have studied shredded recycled foam as concrete aggregate. Both methods are only slightly successful for very different reasons. New beads are round and smooth which is the worst shape and surface for a concrete aggregate
