Early age cracking of concrete has re - emerged as an important issue all over the world in recent years. the stress, due to restrained volume change related to thermal deformation and shrinkage in the early age concrete, is the main driving force for the deleterious cracking in the construction stage. during the development of the stress, creep, a very important property of concrete, is always developing. creep contributes to 40 ? - 50 ? reduction of the elastically induced stress in the restrained specimen. ring test, a qualitative test, can provide information to assess the potential for cracking of different concrete. an overview of ring test developed in recent years and mechanism of uniaxial tensile creep test is described in this paper at first. then, an innovative test equipment based on ring test is outlined
近年來混凝土早期裂縫問題再次引起全球工程界的廣泛關注.早期混凝土由於體積變形受到約束而產生的應力是導致混凝土開裂的主要因素.在混凝土應力發展的同時，混凝土徐變也在同時發生著變化.有研究表明，徐變能減少40 ? - 50 ?的早期應力.圓環試驗是用於定性評價混凝土材料抗裂性能的試驗方法之一.本文首先分析了圓環試驗和單軸拉伸徐變試驗的原理，創造性地將圓環試驗用於測量早期混凝土的干縮徐變，並設計了試驗方案 -
