Calcium-magnesium composite expanding agent as well as preparation method and application thereof
The invention provides a calcium-magnesium composite expanding agent as well as a preparation method and application thereof, and belongs to the technical field of environmental protection and building material production. And calcining the calcium carbide furnace purified ash at high temperature to obtain carbon-free calcined slag. The expanding agent is formed by compounding 85-100 parts of calcium carbide furnace purified ash calcined slag and 0-15 parts of quick lime, the mass ratio of calcium oxide to magnesium oxide of the expanding agent is controlled to be (1-1.5): 1, and the expanding agent is ball-milled to 300-mesh screen residue less than or equal to 10%. The characteristics of high calcium and high magnesium of the calcium carbide furnace purified ash calcined slag are utilized, the mass ratio of calcium oxide to magnesium oxide of the expanding agent is regulated and controlled by doping quick lime, and the expanding agent can meet the standard requirements of T/CECS10082-2020 Calcium-Magnesium Composite Expanding Agent for Concrete. The preparation method is simple, green, environment-friendly and low-carbon, the production cost is greatly reduced, and remarkable environment-friendly, social and economic benefits are achieved.
本发明提供了一种钙镁复合膨胀剂及其制备方法和应用，属环保和建材生产技术领域。将电石炉净化灰高温煅烧成不含炭的煅烧渣。膨胀剂由电石炉净化灰煅烧渣85‑100份，生石灰0‑15份复合组成，控制膨胀剂氧化钙氧化镁质量比为1‑1.5:1，球磨成细度300目筛余小于等于10％。本发明利用电石炉净化灰煅烧渣高钙、高镁的特点，掺入生石灰的调控膨胀剂氧化钙氧化镁质量比，膨胀剂能达到T/CECS10082‑2020《混凝土用钙镁复合膨胀剂》的标准要求。本发明制备方式简单、绿色环保低碳，大大降低了生产成本，具有显著的环保、社会和经济效益。
