Solid waste-based lightweight aggregate based on charcoal internal carbonization and preparation method of solid waste-based lightweight aggregate
The invention belongs to the technical field of green building materials, and provides a solid waste-based lightweight aggregate based on charcoal internal carbonization and a preparation method thereof. The charcoal serves as a key material to provide a channel for CO2 diffusion and transmission and play a role of a temporary CO2 storage tank to supply and transmit CO2 from the inside, on the basis of a traditional carbonization process, the carbonization efficiency can be improved by 118% at most, and the aggregate strength is improved while the aggregate self weight is reduced. The solid waste lightweight aggregate comprises the following components: steel slag powder, brick powder, cement, biochar, zeolite powder, rice hull ash and an additive. The preparation method has the advantages of high preparation efficiency, lightweight aggregate, high strength, no stability problem and the like. When applied to concrete, the concrete curing agent can effectively meet the stacking density requirements of various density grades of lightweight aggregates, and can reduce the humidity loss in the concrete and reduce the self-shrinkage of the concrete as an internal curing agent.
本发明属于绿色建材技术领域，提供了一种基于生物炭内碳化的固废基轻骨料及其制备方法。生物炭作为关键材料为CO2扩散传输提供通道并起到CO2临时“储罐”作用从内部供输CO2，在传统碳化工艺基础上，碳化效率最高可提升118％，在提升骨料强度的同时降低骨料自重。所述固废轻骨料成分为：钢渣粉、砖粉、水泥、生物炭、沸石粉、稻壳灰，外加剂。本发明具有制备效率高，骨料轻质、高强，无安定性问题等优点。应用到混凝土中可以有效满足各类密度等级轻骨料堆积密度要求并作为内养护剂减少混凝土内部的湿度损失，减少混凝土自收缩。
