加气混凝土用铝粉的应用与制备
Application and Preparation of Aluminum Powder Applied in Lightweight Concrete
【摘要】 用干式球磨法生产加气混凝土用铝粉。根据加气混凝土的生产工艺,确定其对铝粉的性能要求。在加气混凝土用铝粉的生产工艺中,通过调整原料铝粉的粒度、助磨剂加入量和磨内滞留时间的工艺参数来控制铝粉的性能。通过实践及数据分析,确定最佳工艺参数:原料铝粉粒度d97=630 ̄280μm;助磨剂加入量在3.0%;铝粉磨内滞留时间为16.6 ̄19h。
【Abstract】 The aluminum powder applied in light weight concrete was produced in mill by dry grinding. The aluminum powder’s performance was decided by the light weight concrete technology. The aluminum powder’s performance were controlled by the material’s particle size, grinding aid’s additions and grinding time.The practice and data were analyzed. The technical parameters were optimized,which was that material’s particle size was d97=630~280 μm, adding 3.0% grinding aid, grinding time was from 16.6 h to 19 h.
