Abstract
Quantitative evaluation of accelerator property and performance-based evaluation of shotcrete have been required with JSCE concrete codes changing to performance-based codes recently. So in this paper, the effect of accelerator on shotcrete performance was evaluated quantitatively and prediction method of shotcrete performance with any mix proportion was developed, using three models established in view of hydration; hydration degree changing model of cement paste with accelerator, plocter penetration resistance development and compressive strength development model. And then performance-based evaluation system of shotcrete was recommended by integrating the three models.
