Cement Bricks Reinforced with Wild Bamboo for Construction of Non-Load Bearing Walls in Areas near the Sea

Abstract

The aim of this study was to investigate both the physical and mechanical properties of wild bamboo, as well as the compressive strength characteristics of cement bricks reinforced with wild bamboo. The intended application is for the construction of non-load-bearing walls in the coastal region to enhance their longevity. Wild bamboo, with a 1.00-centimeter diameter, was incorporated into cement bricks measuring 7.00x19.00x39.00 centimeters. A comprehensive compressive strength test was conducted, and the results were analyzed to assess the structural performance and failure mechanisms of the cement bricks reinforced with wild bamboo. The findings revealed that wild bamboo exhibited a moisture content of 85.03%, wet and dry specific gravities of 1.093 and 0.772, respectively, and a tensile strength of 1,745 kilograms per square centimeter. The bond strength between wild bamboo and concrete was measured at 10.16 kilograms per square centimeter. Cement bricks reinforced with wild bamboo demonstrated an average compressive strength of 63.50 kilograms per square centimeter. Although this represents an approximately 88.20% increase compared to regular concrete blocks, it falls short when compared to unreinforced cement bricks, showing an average of approximately 53.67%. Notably, the primary cause of collapse was attributed to shear forces, indicating that the presence of wild bamboo did not significantly contribute to an increase in the compressive strength of the cement bricks. This study serves as a foundation for future research on concrete walls reinforced with bamboo, providing insights into the potential limitations and areas for improvement in enhancing structural strength.
