Abstract

Abstract: Research on bamboo as a sustainable construction material has received attention from the ages. However, wide variation in physical properties due to its age, moisture content, species type, etc. combined with cement mortar properties affects its bond strength, which further affects its design and thus requires standardization. In this study, a combined experimental and statistical methodology based approach is showcased for standardization and optimization of bamboo-mortar bond strength, incorporating the effect of various factors affecting bond strength. Design of experiments was used to quantify the impact of multiple factors affecting the bond strength between bamboo and cement mortar. Firstly, different experimental pullout tests were conducted to determine the effect of various factors such as water-cement ratio, curing days, cement to sand ratio, fly ash content, and bamboo treatment on bond strength development. Three failure patterns, namely bamboo failure, bond failure, and failure of mortar, were observed. Secondly, using a two-level full factorial design method, different statistical models were formulated. These models (M1- Untreated, M2 - Both treated and untreated) were developed based on bamboo surface treatment. The effect of single factors and their interactions were quantified on bond strength development. The developed models were validated to predict bond strength based on different factors. It was concluded that the developed statistical models predicted and simulated the experimental behavior of bond strength with sufficient accuracy. Finally, an optimum solution for maximizing bond strength based on design factors was presented with higher desirability levels which showcased the beneficial aspects of this standardization approach. Keywords: Bamboo; Bond strength; Design of experiments; Statistical model
