ANÁLISE TÉRMICA DE BLOCOS DE CONCRETO COM ADIÇÃO DE CASCAS DE ARROZ

Abstract

The construction industry is one that generates more waste in big cities. Moreover, in the industrial processing of rice are produced approximately 100 million tons of shells are not always properly discarded. Given the economic and environmental viability, we propose the following work where rice ash obtained from them, are used, along with construction waste, in making ecological blocks. Rice husk was used as alternative materials in replacement of part of the sand. For the evaluation of the thermal properties of concrete blocks (diffusivity, conductivity and specific heat) was used infrared thermography and mathematical model for validation of experimental results. The results were validated metrological point of view, indicating the thermal behavior similar to the standard block. Index Terms - block ecological, vegetable waste, infrared thermography.
