Stochastic Development Model for Compressive Strength of Fly Ash High-Strength Concrete

High-strength concrete (HSC) has been widely used in civil engineering. HSC is a kind of multiphase composite material with large dispersion. In order to improve the safety of structure or component design, it is of great significance to study the variability of HSC mechanical properties and its variation with time. This paper carries out experimental research on the time-varying properties of C80 fly ash HSC under standard curing conditions,...
