Analysis Of The Technical Feasibility Of The Use Of Sericitic Filito As A Pozolic Material In The Production Of Structural Concrete

Resumen

The dilapidation of natural resources is mainly due to industrial activities such as mining and civil construction. Mineral extraction generates a large volume of by-products such as sterile, and in the cement production chain, there are several environmental impacts, such as the emission of carbon dioxide (CO2), which contributes largely to the increase in the greenhouse effect. The Pau-Branco mine, located in the municipality of Brumadinho - MG, belonging to the Quadrilátero Ferrífero, has the sterile one characterized as sericitic filitus, which has pozolanic properties. To promote a more sustainable destination and reduce the consumption of mineral resources for the manufacture of cement, this article presents the analysis of the technical feasibility of concrete produced with the replacement, of 30% by mass, of Portland CP V cement standardized by sericitic filitus. A hunk of concrete was produced that was evaluated in its fresh and hardened state. The results found for compressive strength at 28 days of cement concrete with addition of supplementary cementium material (MCS) demonstrate that this cement is viable for structural purposes.
