Abstract

The invention discloses an environment-friendly paving brick, which is characterized by comprising the following raw materials in parts by weight: 15-25 parts of ceramic waste, 20-30 parts of steel slag, 15-25 parts of coal gangue, 10-20 parts of waste concrete, 15-25 parts of volcanic ash, 5-15 parts of nano silica, 20-30 parts of cement, 5-10 parts of an improved additive, 3-7 parts of a deodorizing additive. The environmental protection paving brick has the advantages of wear resistance, aging resistance, sterility and no abnormal odour, safety and environmental protection, good water permeability and strong ultraviolet absorption capacity; at the same time, the raw materialsare prepared by fully using the industrial waste, the natural resources are saved, the environmental pollution is reduced, and the preparation method is simple, and the method has high practical value and good application prospect.

Description

technical field [0001] The invention relates to the technical field of pavement brick materials, in particular to an environment-friendly pavement brick and a preparation method thereof. Background technique [0002] Steel slag is a by-product of the steelmaking process, and its discharge volume is large, accounting for 15-20% of steel production. With the rapid development of the economy, the rational use of resources and the increasing awareness of environmental protection, the treatment and utilization of steel slag is being paid more and more attention by countries all over the world. Developed countries have their own characteristics in the utilization of steel slag according to their national conditions, but most of them are used for land reclamation, land reclamation, Highway base materials, stockyard backfill and re-smelting raw materials and fluxes, etc. [0003] Ceramic waste slag is the damaged blank produced by the ceramic factory in the process of producing por...
