Description
Technical Field
The invention belongs to the technical field of filling walls in constructional engineering, and particularly relates to a production and construction process of a plastering-free phosphogypsum building block.
Background
The infilled wall is an important component in a frame structure, is built by adopting bricks or building blocks, and plays a role in enclosing or separating in a building. In the traditional filling wall construction process, firstly, a base layer is cleaned, and the position of a masonry wall body is paid off; and finishing the wall tie bars and the constructional column reinforcing bars to be embedded into the wall when the wall is built. When a wall is formally built, firstly, building mortar is mixed, and the number of skins and the number of rows are calculated according to the design size, the module of the building block, the thickness of the horizontal mortar joint and the width of the vertical mortar joint; and then, building the wall according to the requirements of inside and outside lap joint, up and down staggered joint, straight mortar joint and full slurry. After the wall is built, hanging a steel wire mesh at the medium seam, plastering the wall, leveling the surface with gypsum after the plastering is finished, and finally, putty is applied to the wall.
However, it should be noted that the traditional infilled wall has many disadvantages in the construction process, mainly including the following points: 1. the construction process of the filler wall is complicated, and each construction process strictly meets the relevant requirements of the acceptance and acceptance criteria of the construction quality of masonry structure engineering (GB 50203-. 2. The construction of the wall is labor intensive and slow, and besides the need of mixing mortar and laying the wall, the wall tie bars and the constructional column reinforcing steel bars are treated and the constructional column concrete is poured afterwards. 3. The wall masonry needs wet construction, so that the wall masonry height is limited every day, and certain environmental pollution and material waste are brought. 4. After the wall is plastered, the putty coating process can be carried out until the plastered layer reaches the maintenance age (generally 10-15 days). 5. The construction cost of the filling wall is high, and the construction cost of the filling wall generally accounts for 10-20% of the construction cost of the whole project.
The phosphogypsum is often applied to wall engineering of buildings, and has excellent material properties of quick forming, light weight, heat preservation, heat insulation, fire resistance and the like. In recent years, with continuous optimization of phosphogypsum treatment technology, application of the phosphogypsum treatment technology in construction engineering is also more and more extensive. But what is severe is: at present, the stockpiling amount of phosphogypsum in China exceeds 5 hundred million tons, the newly increased stockpiling amount is 6000 million tons every year, the newly increased phosphogypsum occupies about 5000 hectares of land, and the stockpiling of a large amount of phosphogypsum is very likely to cause geological disasters such as landslide and the like and bring environmental problems such as dust, underground water, soil pollution and the like. Therefore, the comprehensive utilization rate of the phosphogypsum in China can be improved by applying a large amount of phosphogypsum in the wall body, and the development concept of green and environmental protection is met.
