Highlights Model to predict build-up thickness was developed and its quality was optimized. Rheological assessment of concrete was compared with existing methods. Zonal effectiveness plot that optimizes shotcrete analysis has been developed. Concept of optimal particle size distribution for wet-mix shotcrete is proposed. Confidence ellipses and prediction intervals were used for rheological analysis.
Abstract In this article, particle size distribution in shotcrete and the diverse effects of admixtures on gradation were discussed. Although admixtures can enhance concrete rheological behavior, they introduce uncertainty into mixture behavior and may lead to segregation, pumping line blockage, and low shootability. Moreover, the assessment of these factors using the Chapdelaine and Burns concepts showed divergence from practical pumpability. We introduced a method to analyze shotcrete behavior using a rheological method that was found more effective. As a result, a model for predicting the build-up thickness was proposed using a statistical method. In addition, a zonal effectiveness plot that could accurately characterize pumpability and shootability, overcoming the uncertainties associated with normal shotcrete analysis methods, was developed using confidence ellipses and prediction intervals that can be used in practical applications in the wet-mixed shotcrete field.
