【摘要】 为了防治混凝土发生裂缝,许多大体积混凝土在设计中提出抗裂要求,徐变是混凝土抗裂能力的重要指标。本文主要研究影响混凝土徐变的因素及提高混凝土徐变的措施。通过适当降低混凝土强度、选用适当的骨料、掺入纤维和聚合物等方法来提高混凝土的徐变,从而提高混凝土抗裂性能,为工程实践提供参考。更多还原

【Abstract】 In order to prevent the crack of concrete,many mass concrete take creep as an important index of crack resistance.This paper analyzes the influential factors of concrete creep and measures for improvement.The creep of concrete can be improved by appropriately lowering concrete’s temperature,choosing applicable aggregates,and incorporating fiber and polyester,which results in the improvement of the crack resistance property of concrete and provides reference for project practices.更多还原
