Abstract:
The effect and optimization of using different types of mortar for both interface and overlays on masonry behavior was investigated by using the Taguchi method. The experimental studies were conducted under varying types of mortar. The mortar was reinforced with a polypropylene (PP) fiber with a volume fraction (0, 1, and 2%) by volume of mortar. An orthogonal array (OA), the signal-to-noise ratio (S/N), and the analysis of variance (ANOVA) were employed to study the performance characteristics of the masonry prisms and walls. The conclusion revealed that the number of overlays and the type of interface mortar were the most influential factors on the masonry prism’s compressive strength and flexural bond strength, respectively. Moreover, the application of mortar overlays increases the wall compressive strength.
