Abstract
The invention provides light anti-cracking plastering mortar, and relates to the technical field of building materials and construction. The light anti-cracking plastering mortar comprises, by weight, 20-30% of ordinary Portland cement, 20-30% of graded sand and stone, 3-15% of glazed hollow beads, 5-25% of ground calcium carbonate powder, 0.1-0.5% of modified polyoxyethylene, 0.01-0.2% of modified cellulose ester water retaining agent, 0.05-0.1% of anti-cracking fiber, 0.3-0.5% of inorganic bentonite, 0-0.01% of sodium dodecyl benzene sulfonate and 0.1-0.2% of powder shrinkage reducing (PSR) agent. By means of the light anti-cracking plastering mortar, the construction performance and crack resistance of the mortar are obviously improved; the light anti-cracking plastering mortar has good heat preservation and sound insulation effects; raw materials can be easily purchased, the production process is simple, mechanized construction is achieved, market application prospects are wide, and the light anti-cracking plastering mortar has the social significance of the refined synergism effect on building energy conservation materials.
Description
Technical field
The present invention relates to material of construction and technical field of construction, be specifically related to a kind of lightweight cracking resistance motar.
Background technology
Autoclave aerated concrete building block be with siliceous material and calcareous material for main raw material, be foaming agent with aluminium powder, add water and stir into slurry, casting, through the porous silicate building block that the techniques such as precuring, cutting, steam press maintenance are made.Because of its light weight there is the impayable performances such as good waterproof, sound insulation, heat insulation, insulation, be widely used in external wall, interior every and roofing etc.The use of this building block is more and more extensive.Have employed grout laid dry technique in construction process, degree of plainness for wall surface is high, meets the effect of thin limed construction, but traditional motar application property in this building block is poor, and the low and dry rear easy cracking with building block cohesive strength, has a strong impact on construction quality.Urgently need one can mechanical execution, splitting resistance good, there is the motar of better cohesive strength and low drying shrinkage.This motar requires to have the material capability close with building block and intensity, to reduce the inconsistent of stress deformation, improves the resistance to cleavage of overall metope.
Summary of the invention
Object of the present invention is exactly to solve the problems of the technologies described above, and provides a kind of lightweight cracking resistance motar.
The part by weight of each component of lightweight cracking resistance motar of the present invention is respectively: ordinary Portland cement 20 ~ 30wt%, graded sand and stone 20 ~ 30wt%, glass bead 3 ~ 15wt%, dicalcium powder 5 ~ 25wt%, modification polyoxyethylene 0.1 ~ 0.5wt%, modified cellulose ethers water-holding agent 0.01 ~ 0.2wt%, anti-crack fiber 0.05 ~ 0.1wt%, inorganic bentonite 0.3 ~ 0.5wt%, Sodium dodecylbenzene sulfonate 0 ~ 0.01wt%, powder economization agent PSR-1000.1 ~ 0.2wt%.
Described graded sand and stone is one or more mixtures in natural siliceous sand, dolomite sand, natural river sand, machine-processed quartz sand, and fineness is 30 ~ 120 orders.Described glass bead is 30 ~ 70 object expanded and vitrified small balls.Described dicalcium powder fineness is 200 ~ 400 orders.Described modification polyoxyethylene for adopting peo resin to be matrix, by sp act substance modification.Described modified cellulose ethers is the one in methyl cellulose ether, hydroxypropyl methyl cellulose ether or ethoxyl methyl cellulose ether, viscosity 20000 ~ 200000mpas.Described anti-crack fiber is one in polypropylene fibre, trevira or wood fibre or two kinds.Described inorganic bentonite is sodium bentonite, lithium bentonite or calcium-base bentonite.
the present invention has the following advantages:
1. obviously improve workability and the splitting resistance of mortar.Building block can adopt the constructional method of mechanically spraying, greatly lifting construction efficiency, significantly eliminate ordinary mortar and whitewash the blockwork and coat of plaster cracking phenomena that cause; 2. there is good insulation, soundproof effect; 3. raw material is easily purchased, and production technique is simple, and mechanization of building operation, market application foreground is wide, and has the social effect of the synergism that becomes more meticulous to building energy conservation material.
Embodiment
The part by weight of each component of lightweight cracking resistance motar of the present invention is respectively: ordinary Portland cement 20 ~ 30wt%, graded sand and stone 20 ~ 30wt%, glass bead 3 ~ 15wt%, dicalcium powder 5 ~ 25wt%, modification polyoxyethylene 0.1 ~ 0.5wt%, modified cellulose ethers water-holding agent 0.01 ~ 0.2wt%, anti-crack fiber 0.05 ~ 0.1wt%, inorganic bentonite 0.3 ~ 0.5wt%, Sodium dodecylbenzene sulfonate 0 ~ 0.01wt%, powder economization agent PSR-1000.1 ~ 0.2wt%.
Described graded sand and stone is one or more mixtures in natural siliceous sand, dolomite sand, natural river sand, machine-processed quartz sand, and fineness is 30 ~ 120 orders.Described glass bead is 30 ~ 70 object expanded and vitrified small balls.Described dicalcium powder fineness is 200 ~ 400 orders.Described modification polyoxyethylene for adopting peo resin to be matrix, by sp act substance modification.Described modified cellulose ethers is the one in methyl cellulose ether, hydroxypropyl methyl cellulose ether or ethoxyl methyl cellulose ether, viscosity 20000 ~ 200000mpas.Described anti-crack fiber is one in polypropylene fibre, trevira or wood fibre or two kinds.Described inorganic bentonite is sodium bentonite, lithium bentonite or calcium-base bentonite.
implement principle:
The present invention chemically reduces and adopts light filler etc. to carry out composition optimizes reduction Mortar shrinkage.Adopt toughness reinforcing, the fiber reinforcement of high molecular polymer, economization agent reduces several aspect such as mortar self-constriction and drying shrinkage and start with simultaneously.Adopting is gelling material with ordinary Portland cement, with inorganic bentonite and modified methylated cellulose ether for water-holding agent makes mortar have good water-retentivity and application property; Take anti-crack fiber as cracking resistance economization agent; Reduce the tension force of pore pressure and its surface compressed with PSR100 economization agent, improve resistance to cleavage; Mortar bonding strength and toughness is improved, reinforced mortar splitting resistance with modification polyoxyethylene; With Sodium dodecylbenzene sulfonate and expanded and vitrified small ball for lightweight matching materials, obtain the microporous structure close with building block and intensity, improve the synchronism of mortar and building block stress deformation, obviously improve the splitting resistance of mortar.
