Abstract

Environmental protection and expensive disposal cost have driven the community and the industry to utilize waste materials for possible product innovations that is beneficial to many. Product innovation using waste materials can greatly help in the construction and manufacturing industry as it can save cost by recycling waste materials. Clay bricks is a type of material that is commonly used in masonry works that are mainly utilized in bricklaying of the wall, room partitions, walkways, and pathways need to be stiff and rigid. The manufactured eco-clay brick (MECB) enhanced with pulverized talaba (Crassostrea Virginica) shell is a kind of bricks that can be used in masonry works. It contained clay and water as a standard mixture with 20% by weight (wt. %) of pulverized talaba shell concentration. The experimental design was employed in this study using standard brick manufacturing methods and materials. Different treatments of MECB with three replications were formed, dried, and fired at 900 to 1000oC for 2h. Properties such as color, texture, density and compressive strength were determined. The results revealed that eco-clay bricks with 20% by weight of pulverized waste talaba shell were the best formulation. The average compressive strength of 23.31 MPa was 135% higher than the standard clay bricks. It could be concluded that the use of pulverized talaba shell as the primary ingredient that enhanced the physical and mechanical properties of the clay bricks which is necessary in masonry works. Innovated construction materials like eco-clay bricks is ecofriendly as it utilized waste talaba shells as compressive strength enhancer. Durable eco-clay bricks met the Philippine standard for making clay bricks and is feasible for mass production to be used in masonry works.
