Abstract:

This research paper focuses on the use of murumuru husk ash (MHA), an agro-industrial waste generated specifically in the Amazon region, as partial replacement of cement in structural concrete. It also evaluates the physical, chemical and mineralogical characteristics of the ash to act as filler in concrete and its properties in the fresh and hardened states in concrete. To this end, the MHA performed physical-mechanical characterization tests, such as specific mass, pozzolanic activity with Portland cement, pozzolanic activity with lime, and BET test, also performing the mineralogical and chemical analysis of the ash. The results showed that there is technical feasibility with partial replacement of 6% of MHA in cement using plasticizer additive to improve workability, thus showing an improvement in the physical-mechanical and durability properties of the concrete.
