Abstract:
With the increase in demand for construction, the use of alternative construction materials is gaining ground in the market every day. Therefore, aiming to reduce the consumption of cement and, consequently, the emission of carbon dioxide, the present work sought to use limestone filler and quartz powder as substitutes for cement in the production of mortar. The waste used in this research is by-products of mining and industry, and is normally discarded as urban solid waste (MSW). The main objective of this work was to study the rheology for possible reuse and application of the residue. Spreading, mass density, incorporated air content and squeeze-flow rheology tests were carried out. The results found were satisfactory and, in general, met regulatory requirements.
