混凝土冻胀破坏成因分析及防冻胀措施分析

Analysis of the Causes of Concrete Frost Heave Damage and Analysis of Anti Frost Heave Measures

北方地区气候寒冷,设计及施工单位在开展室外工程建筑项目时需要考虑混凝土材料的冻胀特性,并结合工程建设的质量要求和产生材料冻胀的主要原因,严格参照国标规范规定,加强混凝土防冻胀的有效处理,不断提升混凝土工程项目的建设质量,避免脱皮、开裂和受冻等隐蔽性质量病害造成工程安全风险等问题。文章对影响混凝土抗冻胀性的主要因素和危害成因进行了综合分析,并结合实际提出了可靠的混凝土防冻胀措施。

The climate in northern China is cold,and the design and construction units need to consider the frost heave characteristics of concrete materials when carrying out outdoor engineering construction projects.In combination with the quality requirements of engineering construction and the main causes of material frost heave,the effective treatment of concrete frost heave should be strengthened in strict accordance with the provisions of national standards and specifications,so as to continuously improve the construction quality of concrete engineering projects and avoid peeling Hidden quality diseases such as cracking and freezing cause engineering safety risks and other problems.This paper comprehensively analyzes the main factors affecting the frost heaving resistance of concrete and the causes of damage,and puts forward reliable measures for frost heaving resistance of concrete combined with practice.
