New Light Weight Mortar for Structural Application: Assessment of Porosity, Strength and Morphology Properties

Abstract

Over reliance on the conventional construction materials majorly contribute to the depletion of the natural sources, this also affects sustainability of the future generation. The natural aggregate sources are being explored at an alarming rate, therefore, the threat of depletion of the natural materials has inspired interest in sustainable construction materials, through utilization of solid wastes and local materials. In this study, an experimental insight on modified mortar, based on strength and microstructural properties, is provided, in an attempt to ascertain the suitability of ceramic industry wastes and laterite as a replacement for conventional aggregates. Various mix proportions were considered, also batching was done by weight when casting the mortar samples. The results showed that there was significant improvement in strength as the ceramic substitution for river sand was increased. However, increasing laterite content beyond 10% negates the strength development in the samples. Overall, the study has developed a suitable lightweight mortar, comprising of 10% ceramic powder, and 100% fine ceramic contents, with strength properties as that of the conventional mixes, and also ecofriendly for use.
