Construction method of the external thermal insulation system using outside insulation mortar and it for midwinter

摘要

The present invention not only can be prevented from freezing even at temperatures below zero, discloses exterior insulation system including outside for the coldest stage adiabatic mortar and it can improve the strength. A Portland cement: 27 to 30% by weight, alumina cement: 1 to 3% by weight, early strength cement: 1 to 3% by weight, silica sand: 40 to 50% by weight, calcium carbonate: 12-16 weight%, polymer binder: 5-7% by weight, cement curing accelerators: 0.2 to 0.8% by weight, cement curing acceleration auxiliary agent: 0.3 to 0.7% by weight, methyl cellulose (methyl cellulose): 0 .15 0.25 wt%, and methyl ethyl cellulose (methyl ethyl cellulose): 0.1~0.2, characterized in that it comprises by weight%, coldest stage for Exterior insulation mortar.FIELD 1
