Method for preparing stable steel slag building block through normal-pressure accelerated carbonization
The invention relates to a method for preparing a stable steel slag building block through normal-pressure accelerated carbonization. The method comprises the following steps: preparing slurry, preparing a steel slag building block green body, preparing a pretreated steel slag building block green body and preparing a steel slag building block. According to the method for stabilizing the steel slag building block, solid waste is subjected to resource utilization, and meanwhile non-pure CO2 and waste heat in industrial waste gas are utilized, so that the whole steel slag building block production process is low-carbon and environmentally friendly; by adjusting various carbonization reaction influence factors, the carbonization reaction of the steel slag building block is accelerated, and the stable and high-strength steel slag building block is prepared within a short time; by monitoring the internal relative humidity of a relatively thick steel slag building block green body, the water content in the steel slag is intelligently adjusted, so that the phenomenon that a compact carbonized product layer formed by surface carbonization reaction hinders inward diffusion and migration of CO2 is avoided, and the carbonization uniformity of the steel slag building block is improved; cO2 in industrial waste gas is permanently sealed in the steel slag building blocks, so that carbon emission in the environment can be reduced.
本发明涉及一种常压加速碳化制备稳定钢渣砌块的方法，包括以下步骤：制备料浆、制备钢渣砌块坯体、制备预处理后的钢渣砌块坯体、制备钢渣砌块。本发明稳定钢渣砌块的方法，将固体废弃物资源化利用的同时，又利用了工业废气中的非纯CO2和余热，使得整个钢渣砌块生产工艺低碳环保；通过调节多种碳化反应影响因素，加速钢渣砌块的碳化反应，在较短时间内制得稳定、高强度的钢渣砌块；通过监测较厚钢渣砌块坯体的内部相对湿度，智能调节钢渣内部的水分含量，从而避免了表层碳化反应形成致密的碳化产物层阻碍CO2向内扩散迁移，提升了钢渣砌块的碳化均匀程度；将工业废气中的CO2永久封存于钢渣砌块中，可降低环境中的碳排放。
