According to the exemplary embodiment of the present invention, above-mentioned basal plane processing and the sprayable anti-hollowing motar of cracking resistance of exempting from Construction method comprises the following steps.
Step A:
Each component is uniformly mixed and made into dry powder and mortar and at the construction field (site) into the dry powder and mortar according to proportioning in advance Add water and mix and the anti-hollowing motar of cracking resistance is made uses, or at the construction field (site) according to proportioning directly by each component with Water mixing is made the anti-hollowing motar of cracking resistance and used;
Step B:
The anti-hollowing motar of cracking resistance that step A is mixed to get is using the mechanically direct building for being sprayed on and needing to construct On surface and catch up with it is flat, maintenance, or by the anti-direct plastering construction of hollowing motar of the cracking resistance need construct building table On face and catch up with it is flat, maintenance.
Dry powder and mortar, which can not be attached on basal plane of plastering, forms mortar plastering layer, it is necessary to added in dry powder and mortar suitable Mortar mixture is made in the water of amount, and mortar mixture has glutinous poly- and thixotropy.The glutinous poly- property of mortar mixture refers to thing in mortar Expect particle surface parcel pellicular water, the characteristic that mortar material particles flock together due to the suction-operated of hydrone;Mortar The thixotropy of mixture refers to mortar mixture by the external force effect more than certain value, and mortar mixture can be plastically deformed, i.e., Mortar particle relative position changes and mortar profile changes.Because mortar mixture has glutinous poly- and thixotropic behavior, it can pass through Mortar slurry is become thin uniform layer and is attached to plaster on basal plane by appropriate construction technology, and mortar plastering layer is formed after hardening.
The glutinous poly- property and thixotropic property of mortar mixture are matched somebody with somebody with the raw material variety of mortar material, grain diameter, level, particle table Surface state, mixing water amount are relevant with mixing time.Mortar material particles are thinner, and phase homogenous quantities material particles specific surface area is got over Greatly, adsorpting water quantity is just more, and mortar mixture sticks that poly- property is good and plastic deformation ability is strong.But meticulous mortar material particles need Mortar mixing water amount it is big, mortar strength is low, contractions is big, then mortar plastering layer easily generation ftracture, hollowing;Mortar material Grain is too thin, then mortar is excessively sticky, and coat of plaster is difficult compacting and low construction efficiency.Mortar material particles are thicker, phase homogenous quantities thing Expect that the specific surface area of particle is smaller, adsorpting water quantity is just few, and the mortar cement consumption of same intensity is small, and identical cement consumption mortar is strong Degree is high;But thick mortar material particles then cause that the glutinous poly- property of mortar mixture is poor excessively, plastic deformation ability is weak and mortar is applied Work is poor, and hollowing easily occurs for mortar plastering layer.Therefore, the modulus of fineness of mortar material particles preferably must be held in zone of reasonableness. When the technical indicator of raw material sand can not meet preparation mortar requirement when, it is necessary to by Mixed With Admixture improve mortar mixture and Yi Xing;It is poor beyond certain fineness modulus scope and surface quality, the sand of motar can not be traditionally prepared, this hair is filled Bright compounding additive, can still make the motar of superperformance, and the present invention can expand the original of production motar Material ranges.
Glutinous poly- property and thixotropy influence of the mixing water amount on mortar slurry is huge, and excessive and too small mixing water amount is all The glutinous poly- property and thixotropy that cause mortar slurry are deteriorated.In order to ensure the workability of mortar construction, mortar mixing water amount is led to Often considerably beyond the water requirement of hydrated cementitious in mortar, these water are evenly dispersed in inside mortar in stirring, when mortar is mixed When compound is stood, due to the mass discrepancy of water and various material particles, coarse granule sinks under gravity, on water and fine grained Float to mortar top and migrate (i.e. so-called mortar bleeding), mortar bleeding changes the uniformity of mortar, causes mortar bottom closely knit And top is larger due to moisture accumulation space, mortar top layer is because bleeding is loose and loses intensity when serious.Come on stricti jurise Say, it is that can not make qualified motar to be not spiked with mortar additive.Traditional mortar additive uses lime paste, by In the environmental pollution of lime paste it is big and in-convenience in use, eliminate substantially now;Use the industrial chemicals of a variety of functions substantially at present Carry out compounding and mortar additive is made, incorporation mortar makes the performance of mortar meet construction and use requirement.
Plastering construction requires that mortar mixture has good rheological property in pressure effect of plastering.Mortar mixture passes through The basal plane discharge of plastering of flow deformation formation mortar plastering thin layer, infiltration is plastered air between basal plane and screed, compacting coat of plaster; After pressure is plastered in revocation, it is desirable to which mortar mixture loses rheological characteristic immediately, keep the shape smeared to be suspended on and plaster on basal plane, Do not slide, do not fall off, until mortar loses plasticity.It is good that spraying application requires that mortar mixture has in the effect of jet impact force Good rheological property, by jet impact force in basal plane or the mortar layer surface formation mortar thin layer of plastering, when losing jet impact After power, the mortar thin layer that injection is formed is attached to plaster basal plane or mortar layer surface, does not fall off, does not slide;Spraying coating process is with smearing Lime and brick requires that mortar has good glutinous poly- property, and mortar drops off few during spraying.The compounding additive that the present invention is developed is fitted extensively For various raw material motars, admixture is compounded after additive, and motar has good glutinous poly- property and thixotropic property, energy It is enough to meet the requirement of plastering construction technique and spray coating constructing technique to motar workability simultaneously, can plastering construction can also spray Apply construction.
The present invention exempts from basal plane processing and when the sprayable anti-hollowing motar of cracking resistance is constructed using plastering technique, smears for one time Grieshoch is up to 20mm, and coat of plaster do not slide, do not ftracture, not hollowing;When being constructed using spraying coating process, uninterrupted coating thickness is reachable 40mm, coat of plaster do not slid, do not ftracture, not hollowing, and spraying is dropped off less than 1%.
The present invention is specialized in for the common quality defect of traditional motar and construction inconvenience, passes through complex art The problems such as measure effectively overcomes common quality defect and the construction inconvenience of traditional motar.It is embodied as, it is additional using compounding Agent reduces mortar cement consumption and mixing water amount, adding of fiber and the rational gradation composition for controlling sand, reduces the contraction of motar Value, it is to avoid mortar plastering layer ftractures and disengages hollowing with basal plane.The water-retaining property of mortar mixture is controlled by compounding additive In appropriate level, effect of impregnation of the increase mortar mixture to the low base material of water absorption rate;Mortar mixture impregnated substrate, which has been discharged, to be smeared The air of grieshoch and basal plane of plastering, adds the bond area of motar and basal plane of plastering, while base material infiltration water suction, triggers Slurry component adds absorption of the basal plane to coat of plaster of plastering, adds motar particle with plastering to basal plane migration of plastering Basal plane it is chimeric;Prevent coat of plaster mortar because hang that power is not enough with basal plane adhesion of plastering or coat of plaster mortar moisture because Action of Gravity Field to Lower migration, coat of plaster cracking, the hollowing for causing mortar plastering layer to slide downwards and occur.Mixed by compounding additive reduction mortar Water is shared, admixture high molecular polymer adhesive improves mortar bonding strength, it is to avoid traditional motar is low because of adhesion strength, Smooth surface and the not mechanical plucking of the small base material of water absorption rate get rid of slurry processing increase surface roughness, mortar plastering layer shrinkage stress The problems such as hollowing being disengaged more than coat of plaster caused by mortar bonding strength and base material of plastering.By filling compound additive, make When base material of plastering draws mortar mixture moisture, the moisture of mortar mixture is maintained at reasonable water to the speed for base material migration of plastering It is flat, prevent on bibulous base material coat of plaster mortar because too fast dehydration, moisture are migrated cause mortar particle not migrate with And lose rheological characteristic rapidly because of dehydration close to the coat of plaster mortar thin layer of substrate surface.Reduced by adding of fiber, flyash Mortar modulus of elasticity, increase mortar cracking resistance deflection simultaneously prevent mortar hardening contraction, humiture change from causing mortar plastering layer change Cracking resistance caused by shape and hollowing, by the thixotroping component and water-retaining component that adjust compound additive so that use different raw material The sand of kind, modulus of fineness and particle surface state can make performance and meet desired motar, and pass through compounding Additive and adding of fiber reduce the spraying of mortar mixture and drop off and prevent coating from sliding.
To sum up, the present invention is actually to be determined to compound the tool of additive according to motar raw material situation and other situations Body component and each component consumption, are achieved in required technique effect.
