A kind of Novel energy saving thermal insulation mortar and preparation method thereof
Technical field
The invention belongs to building material technical field, be specially a kind of Novel energy saving thermal insulation mortar and preparation method thereof.
Background technology
Building mortar is indispensable in construction work, that consumption is very large material of construction.Common building mortar can divide by function masonry mortar, plastering mortar, decoration mortar and extraordinary mortar, can be divided into sand-cement slurry, lime mortar and mixed mortar by consolidating material difference.Mixed mortar has sand-cement slurry, cement clay mortar and lime clay mortar etc.Mortar is sometimes also referred to as non-coarse aggregate concrete, and some basic theories concrete is also applicable to mortar.But, because the composition of mortar is different from concrete with service requirements, therefore, also have the feature of himself, such as, gel material content is many, fine aggregate materials are large, dry shrinkage is large, and intensity is low, is used for building by laying bricks or stones of the porous water-absorbing materials such as common clay brick and smears building surface layer with big area thin layer.Tradition plastering mortar, or common plastering mortar, refers to solid aggregates such as sand for main raw material, the mortar that in addition gelling material is formulated.Its unit weight is comparatively large, poor thermal insulation property.According to the requirement of Ministry of Construction's power-saving technology development program, energy-saving building is by one of important development direction becoming construction industry from now on.Therefore, replacing with light weight, efficiently lagging material the traditional material fallen behind, is the important measures of building heat preservation.At present, country greatly developing energy-conservation, save land, the heat insulating novel wall material that profit is useless, has put into effect regulation and the policy of a series of encouragement novel wall material development in succession.Therefore, work out and there is good workability and cohesive strength, the non-bearing that dry-shrinkage deformed, heat conductivility is close with light block and load bearing heat preserving body of wall anti-cracking heat insulation mortar significant, wide market.
