| Popis: | The generation of new building materials responds to the reduction of energy consumption and regulation of building interior temperatures as strategy to improve energy efficiency in materials engineering and architecture. This research focuses on the study of the rice husk incidence on the physical, mechanical and thermal properties of H10 block manufactured in the metropolitan area of San José de Cúcuta, Colombia. The methodology consists in 4 stages: In first instance, raw material characterization to identify chemical, structural and morphological components of clay and rice husk. Then, H10 blocks manufacturing in 2 clay mixtures, fired at 900 °C, 1000 °C and 1100 °C. Likewise, tests of manufactured samples to analyze its physical and mechanical properties. Parallel to the manufacturing process, transfer and heat fluxes simulations to evaluate surface temperatures and energy concentration of H10 block. In conclusion, rice husk acts as a technological nutrient added to clay mixture and strengthens thermal and insulating capacity of blocks. Nevertheless, the presence of rice husk in clay mixtures increases water absorption capacity of the products, as the percentage of husk increases. And therefore, the compressive strength decreases, which is a factor to consider for the constructive application of H10 block. |
