Abstract： |
The present invention relates to a chemical gesso building material, which consists of the following components according to weight ratio: 30-60 percent of waste gesso, 15-25 percent of powder coal; 20-30 percent of scoria and 5-20 percent of cement material. The chemical waste stone includes titanium gesso and phosphor gesso. The scoria includes titanium scoria, steel residue, water quenching residue and silicon powder stone. The chemical gesso also includes an assistant agent with the weight ratio of 0-5 percent. The preparation method for the chemical gesso building material includes the following steps: the raw materials are to be prepared according to the corresponding weight ratio for each component; the components are mixed and grinded to prepare the material slurry, and then is to be pressed into a mould; the mould is kept for more than 7 days. The present invention uses the chemical waste residue as the main materials and adopts simple process and equipments; without any calcining, the chemical gesso building products with much better physical force performance can be manufactured. The present invention is with much greater economical benefit and social benefit. |
