In this paper, a new energy-saving-and-environmental-protection heat-preservation wall material is studied. This material is mainly made by waste foam, cement and sand in the structure of “sandwich” - cement foamed plastic is in the middle of cement mortar. Experimental study reveals that the heat-preservation block of this material has lighter self-weight and higher compressive strength and better performance in heat preservation, sound insulation and frost resistance, that is to say, its overall property is obviously superior to that of others such as aerated concrete block. This block consumes a large amount of waste foam that is difficult to dispose, which conducive to environmental protection and energy is saving. It can bring favourable social, economic and environmental benefit. Besides, less energy is consumed in the production of this material and it is easy to realize volume production, so this material is a new wall material of energy saving and environment protection.
