Abstract Scope |
In recent decades, the development of new building materials that meet technological, economic, and environmental criteria, especially those that use alternative raw materials or new production methodologies, have become increasingly necessary. In this context, adobe bricks, known for decades in the field of civil construction, proved to be great models of experimentation, since they result from an adequate mixture of soil, sand and natural fibers, apart from also air drying, with no need for calcination. In this work, cattle manure was used as an alternative of natural fiber for the development of adobe bricks, in the levels of 5%, 10% and 15%, to analyze which, one would be ideal. The use of cattle manure in the development of adobe bricks is based on the notion of sustainability, given that this waste is normally disposed of in an improper way, apart from being less polluting than the chemical-industrial fibers. In search for the composition that best meets the regulatory requirements of civil construction, the effects of corrective materials such as Portland cement and hydrated lime were also evaluated, as the main disadvantage of using cattle manure is related to its low durability in places with high humidity. Thus, through this work, we sought to evaluate the durability of adobe blocks, with the proposed formulations, through wetting and drying cycles. In conclusion, it was noticed that the temporal degradation mechanisms of the adobe blocks made of cattle manure could be reduced using corrective materials, stabilizing their durability. |
