Description
ABSTRACT
This project work is aimed at investigating and comparing the strenght of coarse aggregate from different source. These include both the physical and mechanical properties of coarse aggregate materials collected from different sources. The sample is collected from Abakaliki quarry site in Ebonyi State, Lokpanta quarry site in Umunneochi,Abia State and Otanmiri River in Owerri, Imo State, all in South East part of Nigeria. The properties of these aggregates differ from place to place due to the composition of the parent material, weathering and other environmental factors.
Some regulatory bodies like British Standard Institute BSI and American Association of State Highway and Transportation officials AASHTO has formulated standard testing methods for investigating the physical and chemical properties of aggregate. Based on BS and ASTM, some tests were carried out on the different samples which includes; Los Angeles Abrasion test, Aggregate Impact Value test, Specific Gravity and Water Absorption tests, Grading test (sieve analysis) and Compression test. These tests were carried out on the three samples to investigate their properties and finally, a comparison was made on their different properties.
