The invention discloses special dry-mixed mortar for plastering construction via a 2D guniting method. The dry-mixed mortar is prepared from ordinary Portland cement, sulphoaluminate cement, river sand, water, polypropylene fibers, limestone powder, glass powder, coating-grade wollastonite powder, latex powder, rubber powder, cellulose ether, an early strength agent, an expanding agent and a waterreducing agent. The mortar has the advantages of solving the problems of segregation, bleeding, low early strength, no water resistance, low tensile bonding strength, easy generation of initial micro-cracks, rough surface, easy dust accumulation and the like of conventional mortar, and being good in workability, high in bonding strength, capable of effectively preventing the mortar of a plaster layer from falling off, hollowing and cracking, excellent in cost performance and capable of eliminating obstacles in popularization of a mechanical guniting technology; and therefore, a series of problems caused by manual operation are solved.

Thermal bridge dispersion type built-in thermal insulation concrete structure system
InactiveCN101787747BReduce the impactUniform heat transferHeat proofingBuilding material handlingThermal bridgeStructure of the Earth
The invention relates to a thermal bridge dispersed built-in thermal insulation concrete structure system. It includes load-bearing concrete structure layer, thermal insulation material layer and concrete protection layer from the inside to the outside. There are reserved holes at regular intervals along the vertical and horizontal directions of the thermal insulation material layer. There are transverse steel bars, load-bearing concrete structure layer and concrete protection layer in the holes. The steel bars in it are connected to form a tension bridge with the poured concrete, and an inner insulation material layer slightly larger than the reserved hole is fixed on the inner side of the load-bearing concrete structure layer corresponding to the reserved hole. The invention can disperse the thermal bridge effect, balance the heat transfer of the building envelope, significantly reduce the thermal bridge effect, and have good thermal insulation performance; the built-in thermal insulation layer is safe to use and can last the same life as the structure, greatly exceeding the external thermal insulation system 25-year service life; it can eliminate hidden dangers such as easy cracks, hollowing, leakage, and shedding caused by the use of external wall paste and external insulation layers. It combines many advantages such as thermal insulation, earthquake resistance, environmental protection, short construction period, and low cost.
