Refractory castable for trench cover and preparation method of refractory castable
The invention provides a refractory castable for a trench cover and a preparation method of the refractory castable. The refractory castable comprises light mullite, sintered mullite, kyanite, fly ash, activated alumina micro powder, silica fume, calcium aluminate cement and a water reducing agent. The castable for the trench cover can effectively solve the problems that the existing castable for the trench cover is easy to crack and peel off and poor in heat preservation and heat insulation, and a steel structure is easy to deform during use. The trench cover castable designed by the invention has the characteristics of good pouring construction performance, excellent thermal shock resistance, structural stripping resistance, good thermal insulation and the like.
本发明提供一种沟盖用耐火浇注料及制备方法，包括轻质莫来石、烧结莫来石、蓝晶石、粉煤灰、活性氧化铝微粉、硅灰、铝酸钙水泥以及减水剂；本发明沟盖浇注料能有效解决现有沟盖浇注料使用中易开裂、剥落，保温隔热差和钢结构易变形的问题。本发明设计的沟盖浇注料具有浇注施工性能好、抗热震性能优越、抗结构性剥落、保温隔热好等特点。
