Description
Technical Field
The invention relates to special plastering mortar for an aerated concrete wall and a preparation method thereof, belonging to the technical field of mortar.
Background
The aerated concrete is a light porous silicate product prepared by taking siliceous materials and calcareous materials as main raw materials, adding a gas former, and carrying out the processes of proportioning, stirring, pouring, pre-curing, cutting, autoclaving, curing and the like. The aerated concrete has the advantages of light volume weight, high heat insulation performance, good sound absorption effect, certain strength and machinability and the like, and is one of the most widely used light wall materials which are popularized and applied in China at the earliest. An aerated concrete wall is a wall built by aerated concrete, and plastering operation is usually carried out on the wall surface by using plastering mortar.
Lead concentrate, zinc concentrate and tailings are obtained after lead-zinc ore is subjected to a flotation process, the tailings are waste generated after ore dressing in mine production, the discharge amount is large, and the environment is polluted if the tailings are not treated in time.
The prior art has adopted lead-zinc tailings to prepare the masonry aerated concrete, but no people adopt lead-zinc tailings to prepare the plastering mortar of the aerated concrete wall, because the plastering layer is generally a thin layer and is exposed in the air for a long time, the aerated concrete is of a porous structure, the water absorption duration is long, the requirement on the binding property of the plastering mortar is high, otherwise, the phenomena of hollowing and cracking of the plastering layer of the aerated concrete wall surface can be caused, and the safety, the durability of a stabilizing agent and the like of the aerated concrete wall surface can not be well protected. The lead-zinc tailings contain more impurities, and the preparation of the special plastering mortar for the aerated concrete wall with high bonding performance is difficult, and no mature process for producing the special plastering mortar for the aerated concrete wall by adopting the lead-zinc tailings exists in the prior art.
Disclosure of Invention
The invention provides special plastering mortar for an aerated concrete wall and a preparation method thereof, which can effectively solve the problems.
The invention is realized by the following steps:
the special plastering mortar for the aerated concrete wall comprises the following components in parts by weight: 15-25 parts of cement, 5-15 parts of fly ash, 40-50 parts of lead-zinc tailing powder, 20-30 parts of construction fine sand, 0.5-2 parts of polyacrylate, 0.05-0.15 part of hydroxypropyl methyl cellulose ether, 1.5-2.5 parts of latex powder, 0.05-0.15 part of polypropylene fiber and 0.15-0.25 part of lignin fiber.
As a further improvement, the cement is portland cement. The Portland cement is used as a main cementing material and is matched with raw materials such as fly ash and lead-zinc tailing powder to ensure the requirements of compressive strength, tensile strength and dry density of the mortar, if the content of the Portland cement is less than 15 parts, the compressive strength and tensile strength of the mortar cannot be ensured, if the content of the Portland cement is more than 25 parts, the using amount of the lead-zinc tailing powder needs to be correspondingly reduced, the raw material cost of the mortar is increased, the dry density is increased, and the compressive strength and tensile strength of the mortar are not obviously increased. The Portland cement is preferably ordinary Portland cement, more preferably 42.5-grade ordinary Portland cement, and the content of the Portland cement is preferably 20 parts.
As a further improvement, the fly ash is class II fly ash. The fly ash is used as an auxiliary cementing material and mainly plays a role of a cementing material and a filling aggregate so as to facilitate the molding and construction of the mortar, if the content of the fly ash is less than 5 parts, the amount of the slurry in use is influenced, and if the content of the fly ash is more than 15 parts, the dry density of the mortar is increased, so that the use performance of the mortar is influenced; the content thereof is preferably 10 parts.
As a further improvement, the nominal grain size of the lead-zinc tailing powder is 0.05-1 mm. The grain size of the lead-zinc tailings is very critical to the performance of the mortar, when the nominal grain size is larger than 1mm, the slurry is easy to stratify, the tensile strength of the mortar is not enough, and when the nominal grain size is smaller than 0.05mm, the compressive strength of the mortar is not enough. The lead-zinc tailing powder is obtained by crushing through a crusher.
As a further improvement, the building fine sand is 40-140 mesh grade sand. The building fine sand is used as a framework supporting material of the mortar and is matched with the portland cement to further enhance the compressive strength of the mortar.
As a further improvement, the polyacrylate is one or more of potassium polyacrylate, ammonium polyacrylate and sodium polyacrylate.
As a further improvement, the latex powder is preferably a re-dispersible latex powder which has extremely outstanding bonding strength, improves the flexibility of the mortar, endows the mortar with excellent alkali resistance, and improves the bonding strength, the breaking strength, the water resistance, the plasticity, the wear resistance and the workability of the mortar.
The preparation method of the special plastering mortar for the aerated concrete wall comprises the following steps:
s1, weighing cement, fly ash, lead-zinc tailing powder and construction fine sand according to the proportion, mixing the weighed cement, fly ash, lead-zinc tailing powder and construction fine sand accounting for 45-55% of the weighed construction fine sand, and uniformly stirring in a stirrer to obtain a premix A, preferably stirring for 50-80S by using a dry powder mortar stirrer;
s2: weighing polyacrylate, hydroxypropyl methylcellulose ether, emulsion powder, polypropylene fiber and lignin fiber according to the proportion, mixing, adding into the premix A in the step S1, and uniformly stirring in a stirrer to obtain a premix B, preferably stirring for 60-120S by using a dry powder mortar stirrer; the polyacrylate is a water-retaining agent with excellent performance, and the lead-zinc tailing powder is modified, so that the water-retaining property and the cohesiveness of the plastering mortar are improved; the hydroxypropyl methyl cellulose ether, the polypropylene fiber and the polyacrylate are mutually matched to play a role of synergy, so that the water retention property and the bonding property of the mortar are further improved; the lignin fiber can ensure that the mortar has good uniformity, and further enhance the anti-cracking performance of the mortar;
s3: and (4) adding the residual building fine sand in the step (S1) into the premix B, and uniformly stirring in a stirrer to obtain the special plastering mortar for the aerated concrete wall, wherein the stirring is preferably performed for 3-5min by using a dry mortar stirrer.
In the method, the main materials are fully and uniformly mixed in step S1, then the main materials and the auxiliary materials in step S2 are interacted, and finally the residual fine building sand is added, so that the defect that the bonding performance of the mortar is poor due to non-uniform mixing and caking of the main materials is avoided, and the bonding performance and the compressive strength of the mortar are improved. The stirring time of each step is also critical, the stirring time in the step S1 is 50-80S, the stirring time in the step S2 is 60-120S, if the stirring time is too short, the stirring is not uniform, the adhesive property of the mortar can be reduced, if the stirring time is too long, the main material and the auxiliary material are mixed and then dried and hardened, the interaction between the auxiliary material and the main material in the subsequent steps is not facilitated, and the performances of the mortar such as water retention property, adhesive property, compressive strength and the like are difficult to guarantee.
