Effect of lignocellulosic corn waste addition on the porosity, density, and compressive strength of fired clay brick

摘要

Conventional bricks are manufactured from clay with high firing temperatures. However, this method results in the depletion of clay and an increase in energy consumption. In addition, biomass lignocellulosic waste such as corn also increased along with population growth. Some studies reported the utilization of corn lignocellulosic waste to protect the environment in the biomass refinery. Therefore, this study aimed to examine the potential of corn lignocellulosic waste addition in the fired clay bricks production. The mixing of clay/corn lignocellulosic waste (500 μm size) with a ratio of 2.5% of the total weight of bricks was used in the manufacturing of fired brick. The raw bricks were then burned by using a temperature of 600°C. Then, the influences of corn lignocellulosic waste impregnation fired clay brick was examined in terms of density, porosity, and compressive strength. The density of the mixture of clay/corn lignocellulosic waste brick was lower than clay brick, 1.437 gram/cm~3 versus 1.521 gram/cm~3, respectively. The porosity of the mixture of clay/corn lignocellulosic waste brick was lower than clay brick, 27.3% versus 35.79% respectively. However, the compressive strength of the mixture of clay/corn lignocellulosic waste brick was higher than clay brick, 6.81 MPa versus 4.15 MPa, respectively. This study showed that corn lignocellulosic waste has the potential as partial replacement of conventional raw bricks that the standard requirements were applied.
