Novel white concrete expanding agent and preparation method thereof
The invention relates to the technical field of special cement, and provides a novel white concrete expanding agent and a preparation method thereof. A traditional concrete expanding agent is mainly used for compensating concrete shrinkage and improving the crack resistance of concrete, but the traditional expanding agent in decorative concrete cannot meet the decorative color requirement of the concrete. The novel white concrete expanding agent is prepared by the following steps: proportioning a calcareous raw material, gypsum, an aluminum raw material and a regulator, grinding to prepare a raw material, feeding the raw material into a calcining kiln, calcining for a certain time by adopting petroleum coke and biomass composite fuel, discharging the clinker from the kiln (furnace), rapidly cooling to below 100 DEG C to obtain the expanding agent clinker, mixing the expanding agent clinker with a stabilizer, and grinding to a certain fineness to obtain the novel white concrete expanding agent.
本发明涉及特种水泥技术领域，提供一种新型白色混凝土膨胀剂及其制备方法。传统的混凝土膨胀剂主要用于补偿混凝土收缩，改善混凝土抗裂性能，但在装饰混凝土中传统的膨胀剂无法保证混凝土装饰色彩要求。本发明的新型白色混凝土膨胀剂采用石灰质原料、石膏、铝质原料和调整剂配料，磨细制成生料后，喂入煅烧窑采用石油焦和生物质复合燃料煅烧一定时间，出窑(炉)熟料急速冷却到100℃以下，得到膨胀剂熟料，将膨胀剂熟料掺入稳定剂粉磨到一定细度，得到新型白色混凝土膨胀剂。
