Abstract
Characterization of Azumili Blue River Sand
Beach, Ogbo Hill Sand Beach and Akwuke Sand Beach South Eastern Nigeria were
conducted. The samples were sourced from their deposits. Impurities and other
foreign objects were removed by washing and sorting. The chemical analysis was
carried out using X-ray fluorescence (XRF) to determine the deposit with the
highest silica percentage (%). The results of the chemical analysis show that
the Azumili Blue River Sand Beach is composed of silica SiO2
(93.616%), K2O (0.15%), CaO (0.40%), Fe2O3
(1.68%), Al2O3 (3.051%), and has 0.84% clay content.
Akwuke Sand Beach and Ogbo Hill Beach are next in line, with silica SiO2
(91.72%), K2O (0.17%), CaO (0.48%), Fe2O3
(0.84%), Al2O3 (3.191%), and Agu-Awka clay containing Al2O3
(26.43%), SiO2 (29.84%), and Fe2O3 (1.043%). Azumili Blue River was chosen to perform the foundry properties from
the result because of its highest value of silica. The result of the foundry
properties test conducted with a core sand mixture of 5% Agu-Awka clay and 5%
water content included: green strength (32.02kN/m2), dry strength
(235.65kN/m2), permeability (6.3), compatibility (25.20%). The
result of the particle size analysis showed that over 70.85% of the sand were
retained on the following screens: 0.18mm, 0.125mm and 0.09mm respectively. The
result showed that 3-5% of Agu-Akwa clay content with 3-5% water content is
suitable for making cores for casting of light grey iron, malleable iron and
nonferrous alloys.
