- 在高温天气如何保证要求高的大体积混凝土的施工质量是一个难题。文章介绍了荆门石化总厂射线探伤机房大体积混凝土在高温天气施工的技术方案及关键环节的质量控制。实践证明,选用低水化热水泥、添加合适的减水剂和膨胀剂、优化混凝土配比、采用冰水降温,均是在高温天气保证大体积混凝土施工质量的有效措施。
It is a difficulty to guarantee the high quality for bulk concrete construction in the high temperature weather. The paper introduced the technical program some key link s quality control measures to pour a radiographic examination equipment room in Jingmen Petrochemical General Plant during the high temperature weather. To select low hydration heat cement, to add suitable water reducing agent expansion agent, to optimize water, cement aggregate ratio and to use ice water for reducing temperature are some effective method to guarantee bulk concrete construction quality.2001,6(6): 28-29 收稿日期:2001-9-21作者简介:张建,工程师。1987年毕业于武汉水电人学,现从事土建施工管理及监理工作。通讯地址:湖北省荆门市,邮编:448002参考文献:
