An Assessment of Bamboo Fiber and Recycled Concrete Fine Grain as Replacement to Sand in Concrete Hollow Blocks

Abstract

Concrete hollow blocks (CHB) are widely used in the construction industry due to their strength, durability, and affordability. However, the production of CHB involves the use of large amounts of sand, which is a finite resource and can lead to environmental degradation. In recent years, there has been a growing interest in using alternative materials in concrete production to reduce the environmental impact of construction. This study investigates the use of bamboo as an additive in CHB and the replacement of sand with recycled concrete fine grain (RCFG). The study involved the production of CHB using different ratios of bamboo additives and replacement of sand with RCFG. The physical and mechanical properties of the CHB were then tested and compared to traditional CHB made with sand.
