Abstract
The invention relates to the field of construction. The hydraulic lime-based mortar for plastering the wall comprises a premix and water, wherein the premix comprises the following raw materials: volcanic ash reactant, salt water hardness resistant adhesive, natural sand, lightweight aggregate and additive. After the premix is mixed with water, plastic thixotropic mortar can be formed, and the mortar is trowelled on the wall surface of the building body. The mortar of the invention has extremely low organic volatility and almost no humidity shrinkage, which greatly reduces the risk of crack formation of the mortar. In addition, the mortar can resist various aggressive chemical and physical phenomena, and can be coated on the body wall of a building, so that the body wall of the building is well protected.
Description
Technical Field
The invention relates to the field of buildings, in particular to a building material.
Background
The problems of moisture, acid rain corrosion and the like often appear on the body wall surface of a building, so that the damage to the wall body and the overall weathering of the outer wall can be greatly influenced.
Disclosure of Invention
The invention aims to provide hydraulic lime-based mortar for plastering walls, and the hydraulic lime-based mortar is used for solving the technical problems.
The technical problem solved by the invention can be realized by adopting the following technical scheme:
the hydraulic lime-based mortar for plastering the wall comprises premix and water, and is characterized in that the premix comprises the following raw materials: volcanic ash reactant, salt water hardness resistant adhesive, natural sand, lightweight aggregate and additive.
After the premix is mixed with water, plastic thixotropic mortar can be formed, and the mortar is trowelled on the wall surface of the building body. The mortar of the invention has extremely low organic volatility and almost no humidity shrinkage, which greatly reduces the risk of crack formation of the mortar. In addition, the mortar can resist various aggressive chemical and physical phenomena, and can be coated on the body wall of a building, so that the body wall of the building is well protected.
Detailed Description
In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the invention easy to understand, the invention is further explained below.
The hydraulic lime-based mortar for plastering the wall comprises a premix and water, wherein the premix comprises the following raw materials: volcanic ash reactant, salt water hardness resistant adhesive, natural sand, lightweight aggregate and additive. During production and transportation, the premix is separately processed. Before construction, the premix is mixed with water.
The volcanic ash reactant can be a volcanic ash mixture, and the volcanic ash mixture contains active components such as active silica, active alumina and the like. Or the mixture of the volcanic ash reacts with calcium hydroxide to generate reaction products such as hydrated calcium silicate, hydrated calcium aluminate or hydrated calcium sulphoaluminate and the like. Preferably both the pozzolanic mixture and the reactant of the pozzolanic mixture reacted with calcium hydroxide. The weight percentage of the mixture and the reactant is 1-2: 5. After water is added into the mixture, the chemical reaction can be carried out again, and the hardening of the mortar is accelerated. The time for hardening the mortar is shortened, and the construction period is further shortened. And the reactants are added, and the reactants are reacted once, so that after water is added, part of the reactants are subjected to chemical reaction again, but the reaction degree is relatively soft, and the other part of the reactants are not subjected to chemical reaction any more, so that the mortar coated on the wall surface has a certain form, and the surface of the mortar can keep certain smoothness.
The salt water hardness resistant binder is preferably sulfate, the natural sand has a particle size of preferably 3.75mm, the lightweight aggregate is preferably concrete, and the additive is preferably nitrate. The mass percentages of the volcanic ash reactant, the salt water hardness resistant adhesive, the natural sand, the lightweight aggregate and the additive are preferably as follows: 5:1:1:1:0.5. Preferably, 25KG of premix is added to 4-4.5L of water. The mortar has extremely low organic matter volatility and almost no humidity shrinkage, and can greatly reduce the risk of crack formation of the mortar. In addition, the mortar disclosed by the invention can resist various aggressive chemical and physical phenomena, and can better protect the wall surface of the body of a building.
The premix can also be added with glass fiber. The glass fiber is beneficial to increasing the consistency of the mortar and improving the wall hanging capability of the mortar. The glass fiber can also improve the connection strength of the dried mortar and reduce the probability of cracking and falling off of the wall surface. The glass fiber can also improve the water conductivity and the ability of resisting thermal expansion and cold contraction of the dried mortar, and can protect the wall surface of the body of a building more effectively and longer. The mass percentages of the volcanic ash reactant, the salt water hardness resistant adhesive, the natural sand, the lightweight aggregate and the additive are preferably as follows: 5:1:1:1: 0.5: 0.1. preferably, 28KG of premix is added to 4-4.5L of water.
The foregoing shows and describes the general principles and broad features of the present invention and advantages thereof. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
