Abstract

The invention discloses adhesive mortar. The adhesive mortar is prepared from ordinary Portland cement P.O42.5, high-alumina cement, pulverized fuel ash, coarse whiting, silica fume, ash calcium, quartz sand, sintered color sand raw material waste residues, adhesive powder, cellulose ether, wood fiber, starch ether, polyacrylamide and metakaolin, wherein the CaO content in the pulverized fuel ashis 8% or above, and the pulverized fuel ash is conductive to improvement of the water-absorbing property of slurry and has higher water resistance property. The quartz sand contains coarse and fine starch ether smaller in bonding fineness and higher in viscosity, the overall bonding strength of the slurry is obviously improved, the plate breaking rate is improved, meanwhile the sintered color sandraw material waste residues are used as an admixture of the slurry, and the cost can be effectively reduced. The adhesive mortar is convenient to construct and can be widely applied to construction of various sizes of heat insulation boards, and the labor intensity is reduced.

Description

technical field [0001] The invention belongs to the technical field of building materials, in particular to a bonding mortar. Background technique [0002] At present, the most widely used and most mature technology in my country's building wall energy-saving is the thermal insulation system of the external wall of the thermal insulation board. Therefore, the demand for matching adhesive mortar is also very large. However, the adhesive mortar currently on the market has poor cohesive force, insufficient construction, easy cracking, poor water resistance and other shortcomings, which seriously affect the quality of the project. Contents of the invention [0003] In order to solve the above problems, the present invention provides an adhesive mortar with strong cohesive force, good water resistance, good flexibility and easy construction. [0004] The specific technical scheme is as follows: [0005] A kind of bonding mortar is characterized in that, described bonding mort...
