Abstract

The invention relates to the technical field of concrete, in particular to a special concrete clinker without limerock burdening and a production method of the special concrete clinker. The special concrete clinker without limerock burdening is prepared from the following raw materials in percentage by weight: 4%-6% of ferro corrective raw material copper slag, 8%-10% of sal corrective raw material gangue, 4%-6% of sal corrective raw material silica and the balance of industrial waste slag carbide slag. The production method has the beneficial effects that when the special concrete clinker is produced, the industrial waste slag carbide slag is utilized to completely replace limerock, thus a large amount of limerock can be reduced, 1.25 tons of limerock are saved in terms of each ton of special concrete clinker, 0.511 ton of discharged carbon dioxide is reduced, and the production cost is lowered, thereby reducing or avoiding the pollution of industrial waste carbide slag on environment.

Description

technical field [0001] The invention relates to the technical field of cement, and relates to a special cement clinker without limestone ingredients and a production method thereof, especially capable of saving limestone resources, reducing carbon dioxide emissions, and realizing comprehensive utilization of resources. Background technique [0002] At present, the known production of special cement clinker in the prior art is all produced by limestone as the main raw material, which consumes a large amount of limestone resources, and has a large carbon dioxide emission and high production costs, and with the reduction of limestone resources, the cost will further increase. [0003] There are more and more industrial waste carbide slag, and the environmental pollution is also increasing. How to use industrial waste carbide slag and reduce or avoid environmental pollution is a problem that people have always wanted to solve. Contents of the invention [0004] The invention p...
