摘要
基于数学分形理论对大掺量粉煤灰(HVFA)混凝土力学性能进行了分形表征,结果表明,大掺量粉煤灰混凝土微观分维度随养护期的延长而增大,混凝土3~90 d抗压强度与微观分维度之间存在良好的线性关系。大掺量粉煤灰混凝土的分形特征为建立混凝土宏观性能与微观结构的关系提供了理论依据。
The present paper characterizes mechanical properties of high volume fly ash （HVFA） concrete based on the fractal mathematical theory. It is indicated that fractal dimension of HVFA concrete increases with the increase of curing time, and a good linear relationship between the compressive strength of concrete cured for 3- 90 days and fractal dimension in micro scale. The fractal characteristics of HVFA concrete provides a theoretical basis to establish relationship between the macro properties and microstructure of concrete
