Abstract
The invention relates to a cracking-resistant cement mortar for building plastering, which belongs to building materials, which is prepared from perlite, cement and 801 glue with a volume ratio of (7.5-9):(2.8-3.3):1. The cement mortar solves the cracking, bubbling and poor bonding property problems of the prior plastering material; and has the advantages of high coagulation and setting speed, and good fire resistant, acid and alkali-resistant, thermal insulation and sound absorption properties.
Description
Technical field
The present invention relates to a kind of cracking-resistant cement mortar, belong to material of construction, be used for building and plaster.
Background technology
Traditional sand-cement slurry exists shortcomings such as crack, hollowing, adhesive property difference as plastering material, secondly slow because of setting and hardening speed, plastering process and the last decoration process long construction speed that restricting pitch time.
Summary of the invention
The object of the present invention is to provide a kind of cracking-resistant cement mortar, can solve crack, hollowing and adhesive property difference problem that plastering material exists, setting and harden speed is fast again, and has good fire prevention, acid and alkali-resistance, heat insulating and sound absorption qualities.
Cracking-resistant cement mortar of the present invention, its batch volume ratio is:
Perlite: cement: 801 glue=(7.5-9): (2.8-3.3): 1.
Utilize that perlite is in light weight, thermal conductivity is low, attractability by force, characteristics such as burn into does not burn, freeze-thawing resistant, drying shrinkage and immersion linear deformation rate are little, cracking-resistant cement mortar of the present invention adds perlite, and problem such as avoided plastering with the sand-cement slurry hollowing that occurs easily, crack and sand-cement slurry basic unit cause common quality defects such as hollowing, crack easily to decoration.Perlite itself is nonpoisonous and tasteless, and also fire prevention, acid-proof alkaline is good, has characteristics such as insulation, heat insulation, sound-absorbing, and workability and adhesive property are good, and the ash that lands in the process of plastering is few, constructs and once survives labor and material saving.Use mortar of the present invention, saved the sieve sand that sand-cement slurry is plastered, got rid of operation such as slurry, saved service tools such as stirrer, saved a large amount of artificial and machinery expenses.And setting and harden speed is fast, and the back intensity height that condenses, strong adhesion, resistance to cleavage are good, direct Puttying coating just after having smeared 24 hours, and the maintenance of need not sprinkling water has improved working efficiency greatly, has accelerated speed of application.
The same with common sand-cement slurry, during use, add water medium and mix use, add the hydrophober of volume 1～3% again, workability can be better, and the overall performance after the moulding is better, intensity is higher, sticking power is stronger, cohesiveness is better, and setting and harden speed is faster.
Cracking-resistant cement mortar of the present invention has solved the problem of crack, hollowing and adhesive property difference that plastering material exists, have good fire prevention, acid and alkali-resistance, heat insulating and sound absorption qualities again, and setting and harden speed is fast, is beneficial to the promotion construction progress.
Embodiment
The invention will be further described below in conjunction with embodiment.
Embodiment 1
4# building, sub-district, the safe dragon and phoenix garden of Zibo Zhang Dian people, plastering on inner walls adopts cracking-resistant cement mortar of the present invention, its batch volume ratio is: perlite: cement: 801 glue=8: 3: 1, the NANOTHIX B1490 type hydrophober of admixture 2%, depth of plastering 20mm, construction once survives, compare with common plastering, common plastering needs to divide renderset, and only need get final product for one time with this proportioning mortar plastering, save working procedure one, do not found the crack after plastering.
