包头铝厂焙烧炉炉壁耐热混凝土胀裂事故分析

Accident analysis of the expanded crack of the heat-resistantconcrete on the Baotou aluminium factory bake furnace

耐热混凝土的破损受许多因素影响．通过大量试验，阐明了包头铝厂２０室焙烧炉炉壁耐热混凝土胀裂的原因，主要是由于其配合比、所用骨料粒径和级配等不合理所致．这次分析和试验为耐热混凝土的制作提供了宝贵经验．

The damage of the heatresistant concrete is under the influence of many factors.A lot of experiments show that the expanded crack of the heatresistant concrete on the baotou aluminium factory bake furnace wall is due to the unreasonable mix proportion of aggregating grain size,grain composition and so on.The experiments and anylysis provided a valuable experience for manufacturing heatresistant concrete.
