Preparation method of high-temperature-resistant concrete
The invention relates to the technical field of high-temperature-resistant concrete, and discloses a preparation method of high-temperature-resistant concrete, which comprises the following specific steps: uniformly wrapping waste incineration bottom slag subjected to acid treatment with purple grit mud, then enabling plant fibers to pass through the purple grit mud, and performing high-temperature incineration to form artificial pore-forming fused particles; uniformly spraying amino silica sol on the surface of the ferronickel slag fiber to obtain pretreated ferronickel slag fiber; mixing the artificial pore-forming fused particles, the pretreated ferronickel slag fibers, a cementing material, an alkali-activated solution, an additive and water, performing vacuum pressure forming, and demolding to obtain the high-temperature-resistant concrete. According to the invention, the problems of poor high temperature resistance and low strength at high temperature of common concrete are solved, and the problems of land occupation and environment pollution caused by waste incineration bottom slag, ferronickel slag and the like are solved.
本发明涉及耐高温混凝土技术领域，公开了一种耐高温混凝土的制备方法，具体步骤为：将酸处理后的垃圾焚烧底渣用紫砂泥均匀包裹，接着用植物纤维从其中穿过，高温焚烧，形成人为造孔融合颗粒；在镍铁渣纤维表面均匀喷涂氨基硅溶胶，得预处理镍铁渣纤维；将所述人为造孔融合颗粒、所述预处理镍铁渣纤维、胶凝材料、碱激发溶液、外加剂和水混合，真空加压成型，脱模，得耐高温混凝土。本发明在解决了普通混凝土耐高温性能差、高温下强度低的问题的同时解决了垃圾焚烧底渣、镍铁渣等占用土地污染环境的问题。
