Problems solved by technology

Its main disadvantages are: 1. Its own weight is heavy, and the size of the engineering foundation and beams and columns is increased in the application of construction engineering. The comprehensive cost of the project is high, and it cannot be used in high-rise buildings; The main disadvantages of thermal insulation aerated concrete blocks (boards) are: 1. The production cost is high, and it is very difficult to achieve the ideal price/performance ratio; Combined with beams and columns, it is difficult to meet the code requirements
The common problems of the above materials are high water absorption rate and large shrinkage value, which can easily cause wall cracks in actual construction and application, and the surface paint layer is hollow, cracked and peeled off
The third is hemihydrate gypsum interior wall blocks. The main disadvantages are: 1. Various chemical hemihydrate gypsums vary greatly, and the quality is extremely unstable when used for interior wall blocks. Especially the common problem of phosphorus hemihydrate gypsum is efflorescence. Its comprehensive utilization is curbed; 2. The water absorption rate is high, and it will pulverize when it encounters water. The blocks cannot be used in long-term wet places such as kitchens, bathrooms, etc.; 3. The thermal performance cannot meet the upcoming internal wall insulation requirements
The materials used for external wall insulation are all cement-based materials, that is, the application of cement-based external wall insulation mortar technology. This type of material and construction method have the following disadvantages: 1. The dry sh

Description

technical field [0001] The invention relates to the field of building materials, in particular to an integral pouring material for building walls and a construction method. Background technique [0002] Industrial by-products Various chemical hemihydrate gypsum are produced in large quantities in my country, but the comprehensive utilization rate is very low, especially phosphorus hemihydrate gypsum, whose output is about one-third of the total output, but the utilization rate is only 20%, resulting in serious environmental pollution and serious waste of resources. For many years, the country has clarified requirements and policies for the comprehensive utilization of industrial by-product hemihydrate gypsum. [0003] The General Office of the State Council [2013] No. 1 Document [About Forwarding the Green Building Development Plan of the Ministry of Housing and Urban-Rural Development of the Development and Reform Commission] clearly requires the development of lightweight ...
