摘要
文中采用钢渣、磷渣、磷石膏、废弃砂浆等工业废渣作为原材料,通过加速碳化养护,制备废渣基碳化胶凝材料,并研究其力学性能及吸碳率。结果表明,钢渣和磷渣可制备出具有较高强度的碳化胶凝材料,在特定试验条件下,钢渣基碳化胶凝材料的抗压强度可达到130.1 MPa,且吸碳率达到17.2%。
Using industrial solid wastes such as steel slag,phosphorus slag,phosphogypsum,and waste mortar as raw materials,CO_(2)activated binders were prepared by accelerating carbonization curing,and their mechanical properties and CO_(2)uptake were studied.The results indicate that steel slag and phosphorus slag can be used to prepare CO_(2)activated binders with high strength.Under the experimental conditions used,the compressive strength of steel slag based CO_(2)activated binders can reach 130.1 MPa and the CO_(2)uptake can reach 17.2%.
