Study of strength durability models for GRC: Theoretical overview

摘要: Durability of glass fibre reinforced concrete (GRC) remains a widely studied topic, despite significant material optimization over recent decades. Evaluation strength durability normally employs accelerated ageing tests involving immersion specimens in water at range temperatures for various durations. These results are then used to calibrate number models available the literature. Here we present an overview some these models, all based on similar assumptions regarding fundamental loss process, examining their robustness. First, calibration procedure is examined; secondly influence quantity and quality test determination model parameters discussed. The solution spaces inspected multiple minima which might lead non-unique solutions given scheme. Parameter studies also performed order establish whether prone inherent problems.
