摘　　要：论文基于天津地区冬施混凝土的长龄期强度检测,并依据JGJ/T23-2001《回弹法检测混凝土抗压强度技术规程》、JGJ/T294-2013《高强混凝土强度检测技术规程》,分别使用HT-225型和H450型回弹仪建立了天津地区在冬季施工条件下的混凝土测强曲线,与全国统一测强曲线进行了对比分析,为建立天津地区专用测强曲线提供了参考。Based on the long-age strength test of winter concrete in Tianjin area,and according to the JGJ/T 23-2001“Technical Regulations for Testing the Compressive Strength of Concrete by Rebound Method”and the JGJ/T 294-2013“Technical Regulations for Testing the Strength of High-Strength Concrete”,the concrete strength measurement curves of Tianjin area under winter construction conditions are established by using HT-225 and H450 rebound meters respectively,and compared with the national unified strength measurement curves,the special strength curve of Tianjin area provides a reference.
