Abstract
High quality concrete has a low enough porosity value to achieve high density. The purpose of this study was to measure the performance of high-quality concrete blocks by using bamboo reinforcement and bamboo fiber as additional materials. The use of super-liquefying additives from fly ash and palm kernel shells, and high-quality low-grade FAS Tilapia Concrete enhances the concrete experience. Based on (ACI, 2014), it is classified as high-quality concrete with a compressive strength greater than 41.4MPa. Reinforced concrete is a structure made by mixing coarse aggregate, fine aggregate, water, cement, and steel aggregate. Fiber concrete is concrete in which fibers evenly mixed with concrete mortar. The fibers in this concrete serve to retard cracking and reduce brittleness, making the concrete thinner than regular concrete. Using fibers up to 1.5 µm in high-quality reinforced concrete blocks, the maximum deflection reached 23,200 mm for LVDT 5, 0.000 mm for LVDT 3 and LVDT 4, and 37.565 mm. As a result, no shear cracks occurred, and only flex cracks occurred. This is because bending stiffeners are weaker than sliding bones. To increase the flexural strength of bamboo reinforcing blocks, the amount of tensile and compressive bamboo reinforcement should increase to double the amount of reinforcement used in this study.
