STUDY OF THE INTERACTIONS AMONG SELF-LEVELING MORTAR COMPONENTS USING THE TAGUCHI METHOD
Abstract
The search for efficient solutions in civil construction has led to the growing use of self-leveling mortars (SLM), which stand out for their fluidity and workability. However, there are still no normative specifications for their mix design, and SLM requires high consumption of fine materials, especially Portland cement, in addition to wide variability in the amount of admixtures used. Therefore, this study aims to optimize the mix design of SLM using the Taguchi method to analyze interactions among components and improve their rheological properties, minimizing the number of tests and materials, thereby promoting sustainability. Five independent variables were evaluated: cement, limestone filler, sand, water, and superplasticizer admixture, with spread flow as the dependent variable. The results indicated that fluidity is strongly influenced by the superplasticizer admixture, followed by water and limestone filler, while cement and sand had more subtle effects. Furthermore, the study provides guidelines for efficient mix design with reduced Portland cement consumption.
