The practice of external wall thermal insulation mortar is based on the research and summary of the functions and construction methods of thermal insulation materials at home and abroad, which belongs to the domestic external wall thermal insulation method. The thermal insulation layer mainly adopts polystyrene board as the main body of the thermal insulation layer, and the edge of polystyrene board is not suitable for the construction of polystyrene particle insulation material. The combination method of this method is board sticking method and plastering method. The method of external wall thermal insulation mortar is as follows:

　　1.用清水清洗結構混凝土表面浮塵;用泡沫膨脹機將墻體孔密封至8~10深，表面不小于50×50平方米，密實無裂縫;外墻預埋孔全部用C20細石混凝土分兩次密封，然后用防水外墻保溫砂漿比原基層粉刷，與墻孔做法相同;

　　1. clean the floating dust on the surface of the concrete structure with clean water; seal the wall hole to 8~10 depth with the foam expander; the surface is not less than 50 * 50 square meters; there is no crack in the wall; the embedded holes in the external wall are all sealed with two times of C20 fine stone concrete, and then the waterproof exterior wall thermal insulation mortar is brushed with the original base powder, the same as the wall hole.

　　2.冷橋部分:即與混凝土和磚砌體部分或兩種不同的材料,901膠水與一定比例的水混合批刮1:0.5 4 - 10%的水泥砂漿,耐堿玻璃纖維凈,然后刷,和實施噴水維護至少3天;

　　2. Cold bridge part: that is, with concrete and brick masonry parts or two different materials, 901 glue and a certain proportion of water mix to scrape 1:0.54-10% cement mortar, alkali resistant glass fiber clean, then brush, and implement water spray maintenance for at least 3 days;

　　3.混凝土表面經過粗化處理后，由團隊選用液體界面劑進行噴涂，待強度達到后再進行噴涂水養護;

　　3. After the concrete surface is roughened, the team shall select liquid interface agent for spraying, and then spray water curing shall be carried out after the strength reaches;

　　4.制定灰色蛋糕搜索規則。主體結構檢查完畢后，首先對結構細節進行全面審查。

　　4. Develop Grey Cake search rules. After the main structure is inspected, the structural details shall be comprehensively reviewed first.

　　外墻保溫砂漿選用膏、抹組合法可用于外墻保溫工程，并可用于外墻保溫工程。與國內外同類材料相比，該方法具有良好的表面彈性和抗沖擊性能，優異的防水、耐污染和耐候性，是一種提高工程質量、降低成本、加快施工進度的外墻保溫方法。

　　The paste and plaster combination method can be used for external wall thermal insulation engineering and external wall thermal insulation engineering. Compared with similar materials at home and abroad, this method has good surface elasticity and impact resistance, excellent waterproof, pollution resistance and weather resistance. It is an external wall insulation method to improve project quality, reduce cost and accelerate construction progress.
