Preparation process of cement-based grouting material using kaolin
The invention discloses a preparation process of a cement-based grouting material using kaolin. The invention relates to the technical field of concrete production and preparation. The method comprises the following steps: S1, screening the kaolin; S2, activating the kaolin, to be more specific, the kaolin in the step S1 is calcined in three stages in sequence, in the first stage, the calcining temperature T1 is 690-710 DEG C, and the calcining time t1 is 80-100 minutes, the calcination temperature T2 of the second stage is 740-760 DEG C, the calcination time t2 is 200-220 min, the calcinationtemperature T3 of the third stage is 790-810 DEG C, and the calcination time t3 is 80-100 min; S3, performing heat preservation treatment; S4, performing cooling treatment; S5, performing ultrafine crushing, and S6, mixing. The method has the technical effects of excellent kaolin activation performance, simple activation mode and low cost.
本发明公开了一种应用高岭土的水泥基灌浆料的制备工艺，涉及混凝土生产与制备的技术领域，包括以下步骤：S1.筛选高岭土、S2.高岭土活化处理：将S1步骤中的高岭土依次进行三个阶段的煅烧，第一阶段的煅烧温度T1为690‑710℃、煅烧时间t1为80‑100min，第二阶段的煅烧温度T2为740‑760℃、煅烧时间t2为200‑220min，第三阶段的煅烧温度T3为790‑810℃、煅烧时间t3为80‑100min；S3.保温处理、S4.降温处理、S5.超细粉碎、S6.混料。本发明具有高岭土活化性能优异且活化方式简单、成本低下的技术效果。
