Novel process for preparing masonry material by waste solidification treatment

Abstract

The invention discloses a novel process for preparing a masonry material by waste solidification treatment. The process comprises the following steps of: sorting domestic wastes, removing plastics and metals from domestic wastes and grinding to pieces with a maximum size less than 5 mm; grinding building wastes to granules with a maximum size less than 3 mm; mixing quicklime powders, sulfo-aluminate cement, gypsum powders and calcium sulphoaluminate powders to produce a solidifying agent; mixing the domestic wastes, the building wastes and the solidifying agent to form a mixed base; and loading the mixed base to a preset mould and performing pressure-molding, standing for 36 to 72 hours at room temperature and normal pressure, demoulding, and naturally curing for 28 to 30 hours, to obtainthe masonry material. According to the invention, the domestic wastes and the building wastes are pretreated and then mixed with the ideal solidifying agent to produce the masonry material, so that the process of waste pretreatment is simplified to the greatest extent and the cost of waste treatment is reduced. The process has a low investment and a low cost and takes a good effect.

Description

technical field [0001] The invention relates to garbage treatment and utilization technology, in particular to a process for preparing masonry materials through solidification treatment of garbage. Background technique [0002] At present, domestic waste is usually treated by means of classified recycling, landfill, incineration, etc. These methods are less effective, polluting, and cost more, while construction waste is usually disposed of by landfill and foundation. The Chinese patent discloses a "solidification process for waste treatment and utilization". This process can solidify domestic waste into masonry materials, so that domestic waste can be well processed and utilized. However, the disadvantages of this process are: 1. It can only treat domestic waste Garbage, construction waste cannot be processed; 2. The process of domestic waste pretreatment is cumbersome, and the pretreatment of domestic waste needs to be dried or incinerated before being crushed, which takes...
