Abstract

The invention relates to a cast-in-situ wall material. The cast-in-situ wall material is composed of a waterproof cushion material and an ardealite wall material. The waterproof cushion material comprises, by mass, 35%-45% of sulphoaluminate cement, 1%-3% of ultra-fine fly ash, 45%-55% of quartz sand, 3%-6% of expanding agent, 0.1%-1% of thickening time control agent and 0.5%-1% of water reducing agent. The ardealite wall material comprises, by mass, 78%-90% of ardealite powder, 8%-20% fly ash, 1%-3% of cement, 0.2%-0.5% of retarder, 0.1%-0.5% of water reducing agent and 0.05%-0.10% of air-entraining agent. The cast-in-situ wall material has the advantages that due to the fact that the cast-in-situ wall material is constructed in a layered pouring mode, labor force can be reduced, and construction efficiency is made higher.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a cast-in-place wall material. Background technique [0002] At present, in the construction of building interior walls, the building structure model adopted is: use aerated concrete blocks, gypsum blocks, etc. as frame structures, and then plaster and level the blocks to make walls. This construction method has many disadvantages: a large amount of labor, a large amount of labor is required, and the labor intensity is high, and the labor efficiency is low, resulting in high comprehensive construction costs. With the continuous increase of labor cost, it has become a hot issue in the field of construction to seek the construction scheme of how to save labor. [0003] Phosphogypsum is the most important industrial by-product in the production of phosphorus chemical industry in my country, and it is the precipitate mainly composed of calcium sulfate dihydrate discharg...
