Abstract

This project proposes the study of mortars containing waste rubber, vermiculite, and sisal fibers, intended to produce precast plates used in constructing low-cost cisterns. The National Program to Support Rainwater Harvesting and Other Social Technologies (Cisternas Program), financed by the Ministry of Social Development since 2003 (by Law Nº 12.873/2013 and regulated by Decree N° 8.038/2013) promotes access to water through the implementation of simple, low-cost social technologies. In this sense, it is intended to characterize mortar traits through physical and mechanical tests, such as water absorption, void ratio, specific mass, compressive strength, tensile strength by diametral compression, tensile strength in bending, dynamic elasticity module, tenacity, durability test, water quality parameters, and microstructural analysis. Next, we intend to simulate, through a computational package based on the finite element method, specifically the ABAQUS Simulia, the structural behavior of cisterns built with pre-molded mortar plates with the addition of sisal fibers in order to evaluate the maximum storage capacity of these cisterns. The main technological contributions of this project are the composition of a low-cost mortar of simple production, destined to the conformation of pre-molded plates that aim at the construction of cisterns with a capacity varying between 16 m³ and 52 m³, a volume range that would serve cisterns family, school and water production.
