Composite energy saving building blocks and method for making same

The invention relates to a compound energy saving building block and its making method, at present compounded of bearing block, heat-preserving plate, lacing wire, surface layer, and so on. Two ends of the heat-preserving plate are made with inclined anticracking slots, there are air exhaust grooves made on the vertical concave and convex slot, there are cement seam pressure strips on the transverse groove, there are air exhaust holes made on the cement-seam pressure strips, and there are protective films on the lacing wires; and it is made by special techniques of screening antirust low conductive liquor, waterproofing agent and framework material, etc. It has simple and convenient construction, enhances constructing efficiency, has low engineering cost, short working cycle, etc. and it ensures the quality of architectural engineering.
