The performance of cement mortar, and polymer can chronically play a role.Polymeric modification cement-based waterproof mortar has good anti-
Performance is oozed, the toughness of cement-based material is improved, is widely used in recent years in repairing maritime concrete architectural engineering.Secondly,
Polymer-modified cementitious materials have good fluidity, water retention, therefore polymer-modified cementitious materials are in buildings waterproof
Material Field has wide foreground.But polymer-modified cementitious materials are added, and there is also many problems.Compression strength first
Being greatly lowered cannot be resolved with the big problem of shrinking percentage;Secondly polymer is expensive, and polymer addition leads to cement bonded sand
Costco Wholesale is starched to improve.
Most of thermal insulation mortar that the country uses at present still has easy dry shrinkage and cracking, the easy moisture absorption, heat-proof quality general
Disadvantage, it is therefore desirable to one kind making the excellent properties such as exterior wall heat-preserving system has waterproof, antiseepage, adhesion strength is high, weather resistance is good,
Simultaneously in the case where other conditions are constant, additionally it is possible to which the intensity for improving exterior wall heat-preserving system extends the guarantor in the service life of building
Warm adhesive mortar.
