The Portland cement has the advantages of high setting and hardening speed, small dry shrinkage and good wear resistance, and mainly influences the workability, hardening property, strength, shrinkage rate and the like of mortar in the application.
The fly ash is industrial waste residue, is used as one of raw materials of the masonry mortar, can be matched with portland cement to improve the workability of the mortar and the strength of the mortar, and particularly improves the later strength of the mortar. In addition, the fly ash is doped into the masonry mortar, so that the alkalinity of the mortar can be reduced, and the wall body frosting phenomenon is reduced.
Alternatively, in the present application, the SiO is present in an amount of 40 to 50 parts by weight per 100 parts by weight of fly ash225 to 30 parts by weight of Al2O38-12 parts by weight of Fe2O32 to 3 weight portions of CaO, 0.6 to 0.8 weight portion of SO31-1.2 parts by weight of Na2O and 0.05-0.08 weight part of SrO.
In the mortar, the physical action (the micro-aggregate action) is taken as the main action of the fly ash with the chemical components, the particle composition and the workability of the mortar are changed, then the chemical action is taken as the main action in the later period, under the excitation of a hydration product calcium hydroxide of portland cement, the active components of silicon dioxide and aluminum oxide in the fly ash and the calcium hydroxide in the portland cement carry out secondary reaction to generate hydrated calcium silicate gel and hydrated calcium aluminate gel so as to fill the gaps of the mortar and increase the compactness of the mortar, thereby obviously improving the later strength of the mortar.
The addition of the sugar calcium can adjust the fluidity, the dispersion degree and the mortar strength of the portland cement. Specifically, the calcium saccharate is added according to the proportion of the application, so that the angle of repose of the cement can be reduced by 3.5 degrees compared with the condition that the calcium saccharate is not added, and the fluidity of the cement is enhanced. In addition, the fineness of the cement after the calcium saccharate is added can be reduced to 1.88 percent compared with the cement without the calcium saccharate, and the compressive strength is improved by about 2 MPa. It is worth mentioning that the sugar calcium can also be beneficial to avoid cracking and damage of the masonry mortar.
The vermiculite is used as one of the raw materials of the masonry mortar, so that the compressive strength, the flexural strength and the bonding strength of the masonry mortar are improved, and meanwhile, the masonry mortar has better heat insulation performance.
In the application, the vermiculite comprises a first vermiculite and a second vermiculite, wherein the first vermiculite is obtained by calcining a vermiculite raw material at 600-700 ℃ for 40-60min, and the second vermiculite is obtained by soaking the vermiculite raw material at 80-85 ℃ for 4-5h in an acid solution. The obtained second vermiculite wafer is damaged to present a porous characteristic, impurities in the particle channel are dissolved out, and the pore channel is dredged, so that the diffusion of adsorbate molecules is facilitated, and the adsorption capacity is improved. After the two kinds of vermiculite are matched, excessive free water in the mortar can be correspondingly absorbed according to the actual condition of the mortar, so that the dehydration rate of the mortar is hindered, sufficient water is provided for the subsequent hydration of the portland cement in the mortar, and the performance of the mortar is further improved.
Preferably, the weight ratio of the first vermiculite to the second vermiculite is 2-3: 1-2. Under the condition of the proportion, the first vermiculite and the second vermiculite can be uniformly mixed with other raw materials, and the other raw materials can be partially filled in gaps of the vermiculite so as to adjust the water absorption performance of the vermiculite.
The butylbenzene emulsion can reduce the size and the number of microcracks in the masonry mortar, and a microfiber space network structure after the emulsion loses water is formed, so that the compactness of the mortar is improved.
The hydrophilic group in the acrylic acid modified polyvinyl acetate emulsion can fix the free moisture in the mortar and reduce the too fast volatilization of the moisture. Preferably, in the present application, the particle size of the acrylic modified polyvinyl acetate emulsion is 600-800nm, the viscosity is 300-320MPa · s, and the matching effect of the acrylic modified polyvinyl acetate emulsion and the styrene-butadiene emulsion under the conditions is better.
After the styrene-butadiene emulsion and the acrylic acid modified polyvinyl acetate emulsion are matched, on one hand, a polymer film which plays a role in filling and blocking the internal gap of the mortar can be formed in a silicate cement mortar system, the capillary action of the mortar is reduced, and the volatilization of water is prevented; on the other hand, after the two are matched, the fiber-shaped filaments with dendritic and net-shaped structures can be formed and crisscross in the mortar to form a plurality of polymer connecting bridges, so that the flexibility of the mortar is increased, and the cracks of the mortar caused by shrinkage deformation are reduced.
The bamboo fiber has good dispersibility and flexibility, can form a three-dimensional network structure system in the mortar, has certain viscosity, can inhibit the shrinkage and expansion of the mortar, and improves the stability and durability of the mortar structure.
The basalt fiber has higher elastic modulus, tensile strength, dispersibility and affinity. The net-shaped supporting structure system can form a compact and disorderly distributed net-shaped supporting structure system in the mortar, and after the net-shaped supporting structure system is matched with the bamboo fibers together, the net-shaped supporting structure system can be combined with the mortar by monofilaments with different thicknesses and is uniformly distributed in the mortar in unit volume, so that the adhesion rate of hydration products is improved, the toughness of the mortar is effectively improved, and the capability of the mortar in resisting deformation and cracking is improved.
The lotus leaf hydrophobing agent mainly plays a role in hydrophobing, preferably, the particle size of the lotus leaf hydrophobing agent is 0.1-0.15 mu m, the particle size range is more favorable for improving the hydrophobicity, the hydrophobicity and the waterproofness of the masonry mortar, so that the moisture penetration is effectively prevented, and the lotus leaf hydrophobing group can also reduce the cracking property of the masonry mortar.
The electrolytic magnesium slag and the fly ash can play a role in performance complementation, and can offset part of denaturation caused by instability in a hydration process. Secondly, the magnesium slag has higher internal porosity, and under the proportion of the application, the fly ash can be fully contained, so that the matching effect of the fly ash and the fly ash is improved, and the mechanical strength of the masonry mortar is improved.
Preferably, the particle size of the electrolytic magnesium slag in the present application may be, for example, 6-8 μm, and the electrolytic magnesium slag has a pore size capable of stably containing the fly ash, so that the two are stably combined. In addition, the particle size is beneficial to reducing the contact gap between the electrolytic magnesium slag and other raw materials and improving the mechanical strength of the masonry mortar.
On the one hand, the cost of the masonry mortar can be reduced by matching the raw material components, and on the other hand, the masonry mortar has high strength, strong impermeability, difficult cracking and good construction performance.
In addition, the embodiment of the invention also provides a preparation method of the masonry mortar, which is characterized in that portland cement, fly ash, calcium saccharate, vermiculite, butylbenzene emulsion, lotus leaf hydrophobing agent, bamboo fiber, basalt fiber, acrylic acid modified polyvinyl acetate emulsion and electrolytic magnesium slag are directly mixed according to the proportion. The preparation method is simple, easy to operate and suitable for large-scale production of the masonry mortar.
Preferably, in the preparation process, the fly ash and the electrolytic magnesium slag can be mixed firstly, and then the mixture is mixed with the rest raw materials, so that the fly ash and the electrolytic magnesium slag are combined firstly, and the effect of improving the mechanical strength of the masonry mortar after the fly ash and the electrolytic magnesium slag are matched is improved.
