混凝土强度-弹性模量-徐变度的相关性研究

CORRELATION STUDY OF CONCRETE STRENGTH-ELASTIC MODULUS-CREEP DEGREE

为实现对徐变的预测,分析砂浆试件强度-弹性模量-徐变度之间的相关性,结果表明砂浆弹性模量与徐变度的相关性最高,可通过试件弹性模量比较实现对水泥基材料徐变性能预判;通过调整砂浆试件的水胶比和胶凝材料的弹性模量可实现试件徐变度的双向可调;为解决国瑞·西安国际金融中心结构中变形不协调问题提供了新的思路。

In order to forecast the creep, a rationalization proposal is put forward, and the correlation between strength modulus and creep degree of mortar specimens is analyzed. The results show that the elastic modulus and creep of mortar specimens by the highest correlation degree of creep, effect analysis of cementitious material elastic modulus on the creep properties of cement-based materials is feasible; by adjusting the mortar modulus of water binder ratio and cementitious materials can realize the test of two-way adjustable piece creep. The research results provide a new way to solve the problem of inconsistency between core tube and surrounding concrete frame structures.
