EXPERIMENTAL RESEARCH ON AIR-ENTRAINED CONCRETE

摘要: 结合广东地区高温薄板结构引气混凝土施工实践,通过外加剂与水泥适应性、含气量对引气混凝土泌水、抗裂、变形、热工等性能的试验研究及理论分析,优化高温条件下薄板滑模混凝土施工配合比,提出了薄板结构滑模引气混凝土施工控制建议,以供技术人员施工控制参考。Abstract: The study of the present paper was derived from the construction practice of thin-slab structures under high temperature in Guangdong Province. Via a series of experiments combined with the related theoretical analyses on the compatibility between concrete admixtures and cement,effect of the air void on the various performances of airentrained concrete such as bleeding,crack resistance,deformation,thermal characteristics and the like,this study optimized the mix proportions for slip-formed concrete thin-slab construction. Furthermore,it presented several proposals for construction control of slip-formed air-entrained concrete thin-slab structures. These proposals may serve as technical references for those who are in charge of the construction control.
