A kind of interior wall plastering mortar and its construction method

Abstract

A mixed mix of a lightweight inner wall was mixed with the following weight ratio: 30-35 of ordinary silicate cement; 4-5 cooked lime; 5-10 light materials; 5--fineness is 5--The 25th purpose is 50-60 waste sand for heavy materials; 1.0 antibacterial and mold-proof composite agent provided by Guangzhou Synthetic Trade Company, 0.4 kg of antibacterial mold and mold per kilogram, 0.1 kg of water retention, 0.3 kg of diversified latex powder and diversified latex powder and diversified latex powder and 0.3 kg of diversified latex powder and diversified latex powder and 0.3 kg of diversified latex powder and diversified latex powder and 0.3 kg of diversified latex powder and diversified latex powder and 0.3 kg of diversified latex powder and diversified latex powder and 0.3 kg of diversified latex powder and diversified latex powder and 0.3 kg of diversified latex powder and divergent latex powder and 0.3 kg of divergent latex powder.The composition of the air induction agent is mixed with 0.2 kg; the light collection is the fine -grade -based inorganic vival and short -hole material below 100 destinations.The diluted weight ratio during construction is the inner wall plastering mortar: water = 100: 30-50.The mortar uses waste sand in the construction waste as the mortar. It uses materials to recycled, and the crack resistance is good.The adhesion intensity meets the requirements. It can be used with lightweight walls to prevent air drums, cracking, falling off, and ensuring the quality of the project; low unit area cost; can reduce mold and bacterial breeding.

Description

technical field [0001] The invention relates to a construction mortar, in particular to an interior wall plastering mortar and a construction method thereof. Background technique [0002] Construction waste refers to the dregs, spoils, waste materials, residual mud and other wastes generated during the construction, demolition and repair of various buildings and structures by construction units or individuals. At present, the amount of construction waste in my country has accounted for 30%-40% of the total amount of urban waste. Calculated on the basis of 500-600 tons / 10,000 square meters, by 2020, my country will add about 30 billion square meters of new construction area, and the newly generated construction waste will be a shocking number. However, the treatment and utilization rate of construction waste in my country is only 5% at present, and most of the construction waste is transported to the suburbs or villages by the construction unit without any treatment, and is ...

Problems solved by technology

However, the treatment and utilization rate of construction waste in my country is only 5% at present, and most of the construction waste is transported to the suburbs or villages by the construction unit without any treatment, and is stacked in the open air or landfilled, which consumes a lot of land acquisition fees, garbage removal and transportation costs At the same time, problems such as dust, dust and sand flying in the process of clearing, transporting and stacking have caused serious environmental pollution.

[0003] In current construction projects, lightweight walls such as aerated concrete blocks are often used, and the specific gravity of aerated concrete blocks is about 600-800Kg / m 3 , still use the existing ordinary interior wall plastering mortar, the composition and weight ratio of this mortar is generally: ordinary Portland cement 18-25, limestone sand 60-75, the specific gravity of this mortar is 1700-1800Kg / m 3 , the elastic modulus of this ordinary interior wall plastering mortar is obviously greater than that of the aerated concrete block, and the elastic modulus of the two does not match, resulting in a large deformation stress on the plastering interface, and then hollowing and cracking

On the other hand, most of the existing mortars use limestone sand. Can urban construction waste be better utilized? Can construction waste be applied to mortar aggregate after treatment? This becomes the subject of the applicant's research and development

In the mechanized construction process, due to the large proportion of the existing interior wall plastering mortar, it is easy to cause the mortar machine to block the pump, pipe, and gun, which hinders the smooth progress of the mechanized construction and the construction efficiency is low
