一、引言混凝土至今还是土建技术人员唯一的按指定性能自行设计的建筑材料。现在,混凝土设计工作正沿着材料科学发展的方向,致力于弄清混凝土的“组分——结构——性能”的关系,进行最佳化设计。掺加粉煤灰,直接影响新拌混凝土的行为与混凝土的水化和硬化过程,组分、结构和
I. INTRODUCTION Concrete is still the only building material designed by civil engineering technicians according to the specified performance. Now, concrete design work is in the direction of the development of materials science. It is dedicated to clarifying the relationship between “component-structure-performance” of concrete and optimize design. Adding fly ash directly affects the behavior of fresh concrete and the hydration and hardening process of concrete, components, structure and
