摘要
为了弄清高性能混凝土的有关力学性能，本文对龄期为５６天、抗压强度６０至１００ＭＰａ（加硅粉或不加硅粉）的高性能混凝土进行了试验研究。分析并讨论了抗压强度随时间变化和受干燥影响的试验结果。通过２０个试件的试验测得了静力弹性模量和泊松比的试验值，并用回归方法导出了弹性模量的线性方程式。
In this paper the high-performance concretes with 56-day compressive strengths of 60 to 100 MPa (with or without silica fume) have been studied experimentally in order to develop information about the mechanical properties of high-performance concrete. Results and discussions are presented regarding compressive strength gain with time,effect of drying. A linear equation of static modulus of elasticity has been derived.The static modulus of elasticity and Poisson's ratio are calculated by regression with testing data of 20 specimens.
