Performance of Palm Oil Clinker Lightweight Aggregate Concrete Comprising Spent Garnet as Fine Aggregate Replacement

The increase in building activity as a result of population expansion has resulted an overexploitation aggregate, with disastrous environmental consequences. Simultaneously, the disposal spent garnet by shipbuilding industry and palm oil clinker mills harms environment needs greater amount landfill space. Therefore, purpose this study was to determine influence fine aggregate substitute on fresh, mechanical, durability properties concrete. Concrete mixes were created using various percentages substitute, including 0%, 10%, 20%, 30%, 40%. workability, compressive strength, flexural splitting tensile modulus elasticity, water absorption, acid resistance cured concrete all determined. It determined that 20% increased strength lightweight positive filler effect densely packed internal structure concrete, allowing it have lowest percentage absorption. same mixtures exhibited least mass change reduction when exposed solution. results established ecologically friendly may be manufactured considerable volumes waste from sectors.
