Thermo-voltage and strength performance of catalysed biomass concrete with Phosphomolybdic Acid and Ferric Chloride as renewable energy source

Abstract

Catalyzed biomass concrete (CBC) is a cutting-edge technology that produces its own voltages when exposed to temperature changes. It is achieved by mixing catalyst and biomass in conventional concrete during fresh state, and the product generates electricity by oxidation. It helps in reducing cement consumption and minimizing environmental effect, yet to produce new renewable energy from concrete itself. Existing studies has proven the voltage effectiveness of CBC but still low in compressive strength, making it not suitable to serve as load carrying component. Hence in this study, a new chemical combination of catalyst in CBC is examined and reported in its voltage and compressive strength performance. Cubes and specimens with catalyst percentage ranging from 5% to 40% were prepared and tested its compressive strength up to 56 days and its voltage performance under three different exposing condition from 0°C to 100°C. The findings show that CBC specimens with such catalyst combination able to produce voltages, where specimens with 40% of catalyst had the highest voltage measurement of 0.443V. While for compressive strength, CBC cubes with 10% of catalyst performed higher than 40%, but the strength captured with new catalyst combination is better that existing study. It is evident that CBC with such catalyst suitable to serve as load bearing component, and at the same time, generating electricity with complete circuit, under temperature different.
