Abstract
The invention discloses gypsum mortar. The gypsum mortar comprises the following components in parts by weight: 25-45 parts of calcined gypsum, 20-30 parts of desulfurized gypsum, 20-30 parts of coal ash, 2-5 parts of polypropylene short fiber, 0.5-2.5 parts of magnesium lithium silicate gel, 0.2-0.5 part of hydroxypropyl methyl cellulose ether, 0.1-0.2 part of FDN high efficiency water reducer, and 0.05-0.1 part of an air entraining agent. The gypsum mortar is convenient for construction, has strong binding power and minimum inflation property, avoids the phenomenon that a floated coat has empty drum and cracks, and has superior use effect compared with the existing national standard of <GB/T28627-2012>.
Description
Technical field
The present invention relates to a kind of gypsum mortar.
Background technology
When tradition is utilized the prepared gypsum mortar of the plaster of paris for building operation, because the gypsum mortar internal stress for constructing is inhomogeneous, do not possess good resistance to compression, fracture resistance, therefore during traditional plastering construction, in technique, plastering construction thickness is limited to some extent, while surpassing 10mm as depth of plastering, answer construction in layer, every layer thickness is controlled in 10mm.Especially when air-entrained concrete building block is plastered, the phenomenon that more easily causes coat of plaster hollowing, cracking, grieshoch to land.
Summary of the invention
To the object of the invention is the defect existing in prior art in order solving, to provide a kind of performance more excellent gypsum mortar.
In order to achieve the above object, the invention provides a kind of gypsum mortar, comprise the component of following weight part: plaster of Paris 25-45 part, desulfurated plaster 20-30 part, flyash 20-30 part, polypropene staple 2-5 part, lithium magnesium silicate gel 0.5-2.5 part, hydroxypropyl methyl cellulose ether 0.2-0.5 part, FDN high efficiency water reducing agent 0.1-0.2 part, air entrapment agent 0.05-0.1 part.
Above-mentioned gypsum mortar optimum ratio is: plaster of Paris 25-45 part, desulfurated plaster 20-30 part, flyash 20-30 part, polypropene staple 2-5 part, lithium magnesium silicate gel 0.5-2.5 part, hydroxypropyl methyl cellulose ether 0.2-0.5 part, FDN high efficiency water reducing agent 0.1-0.2 part, air entrapment agent 0.05-0.1 part, citric acid 0.02-0.04 part.
Wherein polypropene staple preferred length is 3-6mm.
The best proportioning of gypsum mortar of the present invention is: 40 parts of the plaster of Paris, 30 parts of desulfurated plasters, 25 parts, flyash, 3.7 parts of polypropene staples, 0.6 part of lithium magnesium silicate gel, 0.4 part of hydroxypropyl methyl cellulose ether, 0.2 part of FDN high efficiency water reducing agent, 0.06 part of air entrapment agent, 0.04 part of citric acid.
The present invention has the following advantages compared to existing technology: the present invention utilizes lithium magnesium silicate gel can effectively improve aqueous suspension, thickening property, the thixotropy of product, and stability is better; Utilize polypropene staple, effectively improved the toughness of product, improved the resistance to cleavage of mortar, avoided coat of plaster to occur the phenomenon of hollowing cracking; Utilize water reducer and air entrapment agent, effectively improved the ultimate compression strength of product; Utilize citric acid to control the sclerosis of gypsum, improve the plasticity-of mortar, contribute to process and use; Utilize the effectively cohesive force of reinforced mortar of hydroxypropyl methyl cellulose ether; Utilize coal ash instead cement, desulfurated plaster substitutes retardant, greatly reduces material cost simultaneously, is also the megatrend that meets environmental protection and waste utilization.Gypsum mortar easy construction of the present invention, the gypsum mortar cohesive force of preparation is strong, there is microdilatancy performance, make coat of plaster without hollowing cracking phenomena, result of use is better than existing national standard < < GB/T28627-2012 > >.
