This thesis investigates the water absorption and mechanical properties of concrete incorporating granulated copper slag and abaca fiber. Copper slag, a byproduct of copper extraction, and abaca fiber, derived from the leaves of the abaca plant, offer potential benefits in enhancing the durability and waterproofing ability of concrete material. The study explores the substitution of fine aggregates with varying percentages of granulated copper slag and the addition of abaca fiber at same amount. The primary objective is to assess the impact of these materials on the waterproofing capabilities and compressive strength of the resultant concrete. Experimental tests were conducted to evaluate key parameters such as compressive strength, and water absorption. Results indicated that the inclusion of granulated copper slag improved the compressive of the concrete. Abaca fibers reduced crack propagation which results to avoid water entering in concrete. Moreover, the combined use of copper slag and abaca fiber significantly reduced the water absorption rate, demonstrating improved integral waterproofing characteristics. The findings suggest that the effect of granulated copper slag and abaca fiber can produce concrete composites with low water absorption and enhanced durability. This research contributes to the sustainable use of industrial and agricultural byproducts in construction, promoting eco-friendly building practices.
