摘要
本文在对高强混凝土(C80)的抗压强度、弹性模量等早期力学性能和早期收缩进行试验研究的基础上讨论了早期不同干燥开始龄期对高强混凝土力学性能和收缩特性的影响,并对自收缩和干燥收缩在总收缩中的作用进行了分析。
An experimental investigation on mechanics characteristics, such as compressive strength and plastic modulus, and shrinkage of high strength concrete at early ages is presented. The effects of the initial drying age on compressive strength, Young's modulus and shrinkage including autogenous and drying shrinkage are discussed. Further, the contribution of autogenous shrinkage and drying shrinkage strain to total strain is evaluated.
