CHARACTERIZATION OF PULVERIZED PALM KERNEL SHELLS BLOCKS

Abstract

The study focuses on addressing the environmental issue of palm kernel shell waste by exploring its potential use in improving conventional sandcrete blocks. Palm kernel shells are an abundant waste that contributes to environmental pollution when left untreated. The research aimed to substitute crushed palm kernel shells for sand in sandcrete blocks production. Palm kernel blocks with different proportions (2% to 30%) of crushed palm kernel shells were prepared with a standard mix ratio (1:6 cement to sand), and a fixed 0.5 water-to-cement ratio. After 28 days of curing, the blocks with palm kernel shells showed lower density, weaker compressive strength, and higher water absorption compared to the control. Palm kernel shell blocks were found to be lighter compared to conventional sandcrete blocks. Incorporating palm kernel shells in block formulations is a feasible and sustainable solution for addressing weight-related concerns in construction. Palm kernel shell blocks are suitable for building lightweight structures. Using palm kernel shells may offer potential benefits and contribute to sustainable construction.
