Abstract

The invention discloses an architectural hardener and application in the chromium slag building brick, which comprises the following parts: 30-50% calcium aluminate, 30-40% silica, 10-20% bivalent ferric material, 5-10 % tourmaline and 5-7% solid water glass. The making method comprises the following steps: 1) feteching 10-20% chromium, 10-20% cement, 20-50% solid architectural rubbish, 5-15% clay and 1-5% hardener; 2) mixing these raw materials to stir evenly; adding 10-55% water; stirring; making dry hard cement clod; 3) loading the cement into specimen mold; pressing; stripping; culturing.

Description

technical field [0001] The invention belongs to the field of curing agent and its environment-friendly application, in particular to a construction curing agent and its application field in chrome slag building blocks. Background technique [0002] The harm of solid construction waste to the environment and the problem of its disposal and utilization have attracted people's attention day by day. Processing all kinds of building blocks with wastes such as solid construction waste and mining stone chips not only realizes waste utilization, but also is beneficial to environmental protection, which is in line with the national industrial policy on waste utilization to promote the development of circular economy. [0003] Inorganic solid construction waste is mainly composed of muck, residual sand, broken bricks, concrete fragments, pavement asphalt fragments and other wastes, and the content of various inorganic materials varies. If the utilization of inorganic solid constructi...
