|
摘要
远距离运输低坍落度混凝土的坍落度损失率直接关系到建筑工程质量,立足于混凝土坍落度损失率的相关要求,介绍了案例工程,突出混凝土坍落度问题,介绍了工程施工过程中该项问题的研究现状,对不同强度等级的混凝土坍落度进行了观察,并以影响混凝土坍落度损失率的若干因素为前提,提出了2点解决建议,并总结实际施工效果,有助于降低混凝土坍落度损失率。
The slump loss rate of long-distance transportation with low slump is directly related to the quality of construction engineering. Based on the relevant requirements of concrete slump loss rate,the case project is introduced,and the problem of concrete slump is highlighted. The research status of this problem in the construction process of the project,the concrete slump of different grades was observed,and several factors affecting the slump loss rate of concrete were proposed. Two suggestions were put forward,andfinally the actual conclusions were summarized. The purpose of the construction is to reduce the slump loss rate of concrete.
