Preparation method of modified metallurgical waste residue powder, low-carbon high-temperature-resistant ultra-high-performance concrete and preparation method thereof
The invention relates to the technical field of building materials, and particularly discloses a preparation method of modified metallurgical waste residue powder, low-carbon high-temperature-resistant ultra-high-performance concrete and a preparation method of the low-carbon high-temperature-resistant ultra-high-performance concrete. The preparation method of the modified metallurgical waste residue powder comprises the following steps: (1) adding triethanolamine oleate and/or polymethyl methacrylate of which the mass fraction of metallurgical waste residues is 0.01-0.03%, and grinding; (2) adding a proper amount of calcium source or silicon source material to adjust the molar ratio of calcium to silicon; (3) preparing the powder into spheres; (4) carrying out steam curing on the prepared blank body; (5) drying and calcining the cured blank body; and (6) adding diethanolisopropanolamine and/or triethanolamine maleate accounting for 0.01-0.03% of the mass of the metallurgical waste residue powder, and grinding. The application not only can overcome the defects generated after the metallurgical waste slag is applied to the concrete, but also can improve the problems that the existing ultra-high performance concrete is easy to crack and the strength is lost in a high-temperature environment and the like.
本申请涉及建筑材料技术领域，具体公开了一种改性冶金废渣粉的制备方法、低碳耐高温超高性能混凝土及其制备方法；改性冶金废渣粉的制备方法包括以下步骤：(1)加入冶金废渣质量分数0.01～0.03％的油酸三乙醇胺酯和/或聚甲基丙烯酸甲酯，磨细；(2)加入适当钙源或硅源材料调整钙硅摩尔比；(3)将粉体制成球体；(4)将所制胚体进行蒸汽养护；(5)将养护完的胚体进行干燥、煅烧；(6)加入冶金废渣粉质量0.01～0.03％的二乙醇单异丙醇胺和/或马来酸三乙醇胺酯粉磨。本申请不仅可以克服将冶金废渣应用于混凝土中后而产生的弊端，且可以改善现有超高性能混凝土在高温环境中易发生爆裂以及强度损失等问题。
