High-performance ceramsite for lightweight aggregate concrete prefabricated component and preparation method of high-performance ceramsite
The invention discloses a high-performance ceramsite for a lightweight aggregate concrete prefabricated component and a preparation method thereof, the ceramsite comprises an inner core component A and a shell component B according to a mass ratio of 1: 0.15-0.45, the inner core component A comprises fly ash, aluminum slag, quartz powder, silica fume and magnesium slag, and the shell component B comprises limestone, bauxite, aluminum slag, fly ash and gypsum. The ceramsite is prepared on the basis of the firing system of the sulphoaluminate cement and the MgO-Al2O3-SiO2-CaO quaternary phase diagram, so that the firing system of the ceramsite is matched with the firing system of the sulphoaluminate cement, and the high-strength ceramsite with the sulphoaluminate cement shell is fired at a time.
本发明公开一种轻集料混凝土预制构件用高性能陶粒及其制备方法，所述陶粒包括质量比为1：0.15～0.45的内核组分A和外壳组分B，所述内核组分A包括粉煤灰、铝渣、石英粉、硅灰和镁渣，所述外壳组分B包括石灰石、铝矾土、铝渣、粉煤灰和石膏。本发明基于硫铝酸盐水泥的烧成制度和MgO‑Al2O3‑SiO2‑CaO四元相图制备陶粒，使陶粒的烧成制度与硫铝酸盐水泥烧成制度相匹配，实现一次性烧成具有硫铝酸盐水泥外壳的高强陶粒。
