| 摘 要： | 混凝土结构在早龄期往往由于干燥收缩、自身收缩、塑性收缩和温度收缩等因素产生体积变形,若同时受到约束就可能会发生开裂,因此有必要研究混凝土早龄期抗裂性能的测试和评价方法。随着绿色高性能混凝土材料的发展,早龄期混凝土抗裂性能的测试和评价方法仍需进一步研究。 |
| 关 键 词： | 混凝土 体积变形 早龄期 抗裂性能 |

| Abstract: | Cracking of concrete at early age arises from volume changes such as drying shrinkage,autogenous shrinkage,plastic shrinkage and thermal deformation.These volume changes cause tensile stresses in the material when they are restrained.So it is necessary to study the testing and evaluation method of cracking resistance performance of concrete at early age.The testing and evaluation method of cracking resistance performance of concrete at early age need to be further studied with the development of green high performance concrete materials. |
| Keywords: | concrete volume changes early age cracking resistance performance |
