Alkali salt excited carbon sequestration cementing material based on regenerated micro powder and preparation method thereof
The invention belongs to the field of alkali salt-activated inorganic non-metal cementing materials, and particularly relates to a regenerated micro powder-based alkali salt-activated carbon sequestration cementing material, which is prepared from the following components in parts by mass: 40 to 50 parts of regenerated micro powder, 20 to 40 parts of blast furnace slag, 10 to 20 parts of steel slag, 5 to 8 parts of alkali salt activator, 5 to 10 parts of inorganic cementing aid and 0.0005 to 0.002 part of reaction activity accelerant. The alkaline salt exciting agent is Na2CO3; the inorganic gelling aid is MgO; the reaction activity accelerant is basic magnesium carbonate tetrahydrate; the alkali salt excited carbon sequestration cementing material based on the regenerated micro-powder mainly utilizes the regenerated micro-powder, the slag and the steel slag generated in the urban demolition process, and can absorb a part of CO2 and improve the compressive strength in the maintenance process.
本发明属于碱盐激发无机非金属胶凝材料领域，具体涉及一种基于再生微粉的碱盐激发固碳胶凝材料，按质量份数计，包括：40～50份再生微粉，20～40份高炉矿渣，10～20份钢渣、5～8份碱性盐激发剂，5～10份无机胶凝助剂，0.0005～0.002份反应活性促进剂。碱性盐激发剂为Na2CO3；无机胶凝助剂为MgO；反应活性促进剂为碱式四水碳酸镁；本发明基于再生微粉的碱盐激发固碳胶凝材料主要利用城市拆除过程中产生的再生微粉、矿渣和钢渣，且在养护过程中可吸收一部分CO2并能提高其抗压强度。
