[Abstract]:At present, building energy conservation has become a basic national policy in the economic construction of our country, and has had a great impact in the construction industry. And more and more attention has been paid by governments and scientific research departments at all levels. In this experiment, the effects of cementing materials and aggregates on the properties of external wall insulation mortar are studied, and the kinds of raw materials and the best blending amount are determined. In order to improve the comprehensive properties of exterior wall insulation mortar, the cementing materials mainly include cement, latex powder, cellulose ether, wood fiber and polystyrene fiber, and polybenzene particles, vitrified microbeads and expanded vermiculite are selected as lightweight aggregate. This paper briefly introduces the material selection analysis of external wall insulation mortar and the test process and calculation method needed for each performance. This experiment is mainly divided into four groups: the effect of polystyrene particles and glass microbeads as mixed aggregate on the performance of external wall insulation mortar; The effect of vitrified microbeads as a single aggregate on the performance of external wall thermal insulation mortar; The effect of glass microbeads and expanded vermiculite as mixed aggregate on the performance of external wall insulation mortar and the effect of expansive vermiculite as a single aggregate on the performance of external wall insulation mortar. The method of particle size gradation of mixed aggregate for external wall insulation sand. The ratio of design and test of slurry, The main factors affecting the performance of external wall insulation mortar are analyzed. The forming rate of external wall insulation mortar slurry, the compressive strength, flexural and shear strength, water absorption rate and thermal conductivity of mortar test block are taken as technical indexes. The effects of different factors such as aggregate particle size gradation and water-material ratio on the performance of external wall insulation mortar are analyzed and studied. The optimum mix aggregate ratio scheme was selected, and the properties of anti-cracking mortar in external insulation system were studied simply. The amount of cement and the amount of latex powder involved in the test have a certain influence on the external wall insulation mortar slurry and its construction maneuverability. In order to determine the optimum dosage of cement and latex powder, and to compare with this experiment, The contrast tests were carried out by purchasing dry powder external wall insulation mortar from a material processing plant in Hebei Province respectively. Through the comparison and data analysis of several mixed aggregate ratio schemes, it was concluded that the external wall insulation mortar studied in this experiment is of high strength, light weight, insulation and insulation. High bonding strength, fire resistance, low water absorption and environmental protection without pollution. In addition, the external wall plastering test is carried out for the construction of external wall insulation mortar, which is used to optimize the compatibility and maneuverability of mortar slurry, and to observe and record the plastering effect, which is conducive to further improving the test ratio. Better configuration molding is used in building energy saving engineering.
