STUDY ON MECHANICAL CHARACTERISTICS OF AGGREGATES SOURCED FROM THE HILLY TERRAIN OF SANGERE -FUTY GIREI LOCAL GOVERNMENT AREA, ADAMAWA STATE
Abstract
The study aimed to investigate the mechanical characteristics of aggregates sourced from the hilly terrain of Sangere-FUTY and assess their suitability for various construction purposes. The key findings from the Aggregate Impact Value (AIV) Sample A, with an AIV of 32.9%, are marginally suitable for general construction, including sub-base layers, but not for high-impact environments such as road surfaces. Whereas, sample B (40.8%) and Sample C (48.6%) are more suited for non-structural or low-impact applications due to their lower resistance to impact. For the Aggregate Abrasion Value (AAV), all samples (A = 65%, B = 72%, and C = 78%) exceeded the recommended limits for structural applications, making them unsuitable for high-wear surfaces like road pavements or heavily trafficked areas. The study also revealed that the average compressive strength for all samples after 3 days of curing was 12.56N/mm² while after 7 days of curing was 13.54N/mm² falls below the recommended mean strength of 16.80N/mm². This result therefore shows that the samples are not suitable for construction of high strength structures. The study therefore, recommends that governmental and non-governmental agencies can use the aggregates from Sangere-FUTY for non-structural applications where impact and abrasion resistance are less critical, such as landscaping, low-load pavements, or as fill material.
