PROCESS FOR MAKING A THERMAL INSULATION BUILDING BLOCK

摘要

The disclosure herein describes a process for making a thermal insulation load or non-load supporting building block for wall construction which comprises the steps of first pouring a layer of a wet mixture consisting of concrete containing expanded polystyrene beads or other beads of similar cellular lightweight insulating material, laying a board of expanded polystyrene over the wet mixture and then pouring over the board a second layer of a similar wet mixture of concrete containing expanded polystyrene beads or the like; the board of expanded polystyrene is cut from a block of expanded polystyrene so that the opposite cut surfaces may define small cavities into which the wet cement impregnates so that, once the concrete has set, a solid bond is formed between the concrete layers and the board of polystyrene.
