Abstract

The invention discloses a road traffic stone processed and prepared from solid wastes of a blast furnace slag and a pulverized fuel ash, and relates to the technical field of processing of the road traffic stone. The road traffic stone comprises the following raw materials by weight: 40-50 parts of blast furnace slag, 25-35 parts of pulverized fuel ash, 20-30 parts of fine sand, 15-25 parts of Portland cement, 10-15 parts of ceramic waste micro-powder, 5-10 parts of a gelling agent, 3-8 parts of asbestos wool, 1-5 parts of petroleum coke micro-powder, 1-5 parts of polyaluminium sulfate, and 0.5-2 parts of polyborosiloxane. Due to the use of the gelling agent, the solid wastes of the blast furnace slag and the pulverized fuel ash have certain gelling property so as to be favorable for the recycling of the blast furnace slag and the pulverized fuel ash as the main materials of concrete, the blending compatibility between the preparation materials of the concrete is strengthened, the evendispersion of the raw material is guaranteed, the environmental pollution caused by the wasted blast furnace slag and the wasted pulverized fuel ash is avoided, and meanwhile, the mechanical use performance of the prepared road traffic stone is improved.

Description

Technical field: [0001] The invention relates to the technical field of curb stone processing, in particular to curb stone prepared by processing solid waste blast furnace slag and fly ash. Background technique: [0002] Curb stone refers to the boundary stone used on the edge of the road surface, also known as curb stone or curb stone, curb stone. Curb stones are used to distinguish roadways, sidewalks, green spaces, isolation belts and other parts of the road on the road surface, and play a role in ensuring the safety of pedestrians and vehicles and ensuring the tidy edges of the road surface. [0003] Currently, curbs are usually prefabricated from ordinary concrete or cut from natural stones, such as curbs made of granite and marble. Curb stone cut from natural stone is not only difficult to obtain materials and construction, but also has limited resources and damages natural resources, so it has not been widely used in recent years. However, although the price of curb...
