(2) Cast-in-place outer wall insulation system: the heat insulating material is used as core board, and the inorganic protecting surface layer is compounded on both sides of the core board. The basic structure of the heat-insulating formwork consists of a heat-insulating layer, a bonding layer, an anti-cracking protective layer, a heat-insulating transition layer, a bearing rib and the like, which are called heat-insulating formworks for short. The structure is stable and safe, but the method belongs to wet operation, and secondary veneer decoration engineering is needed, so that the construction waste allowance is increased, and the ecological environment is influenced. (3) Self-insulation concrete composite building block: the concrete small building block is produced by the processes of compounding lightweight aggregate in the aggregate and/or filling heat-insulating materials in the holes, and the like, and the wall built by the concrete small building block has a heat-insulating function. The complex forms are of the following types: type I: the self-heat-preservation building block is made by compounding lightweight aggregate in the aggregate; type II: filling a self-heat-preservation building block made of heat-preservation materials in the hole; type III: the self-heat-preservation building block is made by compounding lightweight aggregate in the aggregate and filling heat-preservation materials in the holes. No matter which kind of technology, all be a mechanical physics combination, the stability is poor, and the heat bridge is many, and its concrete material intensity is low, and the compactness is poor, and the space is many, and easy infiltration just needs secondary veneer engineering.
