Abstract
The invention relates to an admixture for a plastering mortar in building, which belongs to a technology field of the building material. The building plastering mortar admixture of the invention comprises fly ash, calcium sulfonate, fat alcohol sulfonate and promoter. The weight percentage of each component is that: the fly ash of 50-80; the calcium sulfonate of 10-30; the fat alcohol sulfonate of 5-20 and the promoter of 5-15. The building plastering mortar admixture of the invention is a powder preparation with an ecological function type and has the advantages of simple production process and a poisonless and harmless admixture. Proved by the application, the building plastering mortar admixture of the invention has the characteristics that the performance of the admixture is stable, the performance price ratio is high, the mixing amount is low and the mixing amounts scope is ranging from 0.05 to 0.4 percent, as well as the using optical mixing amount (cement weight) is 0.1-0.2 percent. The stirred mortar has a good work consistency and cohesiveness performance and the water retaining capacity is greatly improved. The mortar on the wall greatly reduces or removes the quality faults of tympanic, cracking, powdering, loose wall surface when the mortar is hardened.
Description
Technical field
The invention belongs to building material technical field, relate to a kind of construction work building mortar, the mortar additive that sand-cement slurry in particularly a kind of interior external rendering plastered work and mixed mortar use.
Background technology
In recent years, additive for building mortar such as active ingredient for mortars, micro foam agent, lime are clean, mortar king etc. used in construction work, to improving the building mortar workability, saving lime and played certain effect.But at existing mortar additive service condition, by long-term observation and investigation, especially on-the-spot the detection found, effect after additive for building mortar uses is unsatisfactory, quality problems of various degrees in interior external rendering plastered work particularly, employed mortar additive exaggerated propaganda, as fully phase out lime, save cement, improve intensity etc., the workability of mortar covets, sacrifice over-all properties, the weather resistance of mortar, cause and whitewash motar sclerosis back and play the phenomenon that sand, cracking, hollowing, body of wall loosen.Trace it to its cause, the one, recipe ingredient lacks the system optimization combination, and over-all properties is poor; The 2nd, ignore processing requirement during construction, especially under hot dry environment, the mortar dehydration of last wall is too fast, and gelling material such as cement can not get abundant aquation and make loss of strength; The 3rd, bleed is excessive, too pursues workability, and the volume value range is narrow, in case super mix cause mortar hardening after later strength sharply descend.
Summary of the invention
At mortar additive above shortcomings and defective in the building mortar technology, the invention provides a kind of building plastering mortar additive, make up by optimization of formulation, coordinate synergy between the component mutually, make mortar have the works fine denseness, improve the sustainable water retention capacity of mortar, make from maintenance and fully aquation of sand-cement slurry, improve constantly the sand-cement slurry cohesive strength, to solve the quality problems of above-mentioned mortar.
Building plastering mortar additive of the present invention is made up of flyash, calcium sulphonate, fatty alcohol sulfonate, auxiliary agent, and wherein each constituent mass percentage composition is as follows:
Flyash: 50～80%;
Calcium sulphonate: 10～30%;
Fatty alcohol sulfonate: 5～20%;
Auxiliary agent: 5～15%.
Building plastering mortar additive of the present invention is ecological functional type powder formulation, has simple, the nontoxic advantage of production technique.Proof after using, additive for building mortar stable performance of the present invention (performance perameter sees Table 1), the cost performance height, volume is little, and the volume scope is between 0.05～0.4%, and the optimum mix amount during use (cement is heavy) is 0.1～0.2%.Mortar after the stirring has good operation denseness and adhesive aggregation performance, and its water retention capacity greatly improves.Metope hollowing, cracking, efflorescence, common quality defect such as loose have been reduced or eliminated on the mortar after the wall sclerosis greatly.Additive for building mortar of the present invention carries out reasonable formula optimization at the defective of existing mortar additive, except reaching existing performance of mortar and characteristics, and increase outside the performance of product, make metope have from respiratory function, help sand-cement slurry to utilize that steam carries out persistence for a long time from maintenance in the environment, guaranteed that the abundant aquation of sand-cement slurry reaches suitable strength.The characteristics of have waterproof, antisweat, damping after the sand-cement slurry sclerosis, preserving moisture have enlarged range of application.
