引气抗冻混凝土在东北地区的应用

Application of Air-entraining Frost-resistant Concrete in Northeast Region

结合工程实际,在沈平高速公路改扩建工程中采用了引气抗冻混凝土。根据引气抗冻混凝土的要求,进行混凝土配合比设计,结合引气抗冻混凝土的特点,采取相应措施控制原材料质量和混凝土质量,通过对混凝土施工质量进行检验,确定了合理的施工工艺。

In combination with engineering practice, the air - entraining frost - resistant concrete is adopted in the reconstruction and extension project for Shenyang - Siping Expressway. According to the requirement of air - entraining frost - resistant concrete, the concrete mix proportion design is performed. In combination with the features of air - entraining frost - resistant concrete, corresponding measures are taken to control the quality of raw materials and concrete quality, the inspection is made for the concrete construction quality, and reasonable construction technology is determined.
