Assessing flow response of self-compacting mortar by Taguchi method and ANOVA interaction

Abstract

Self-compacting mortar (SCM) is a new generation product and has prospective use as an independent material as well as an integral constituent of self-compacting concrete (SCC). In this paper the flow response of self-compacting mortar is assessed by Taguchi method and ANOVA interaction. Effect of powder material and super-plasticizer on the relative flow index of fresh SCM is evaluated by mortar trial test designed by Taguchi method of optimization. An ANOVA interaction analysis is performed to comprehend the interaction of the factors and their effect on quality characteristic. The relative significance level of powder material and super-plasticizer in governing the flow characteristic is discussed. A modified approach is proposed by incorporation of the error balancing property of statistical central tendency and the assumption of non-variance of mean. Construing contribution of mean, sample size and relative error to Signal to Noise Ratio provides limits of deviations of the same.

Self-compacting mortar with sugarcane bagasse ash: development of a sustainable alternative for Brazilian civil construction

“…The self-compacting mortar (SCM) offers several benefits associated with the product and the operational processes, both in precast plant operations and in direct applications at construction sites. The developments of by-products associated with self-compacting concrete (SCC), such as the paste and SCM, are also fundamental for the determination of the self-compacting properties of the self-leveling concretes (Safi et al 2013;Chatterjee and Das 2013). In this context, there are a lot of studies that have developed SCM with the most varied materials (nanoparticles, industrial residues as the aluminum, among others) to improve the characteristics of resistance, workability and consumption, proposing at the same time, the use of new components in a technical and controlled way (Rao et al 2015;Silva and Brito 2015;Mohseni et al 2015;Madandoust et al 2015).…”
