Abstract

Analysis of SiO 2 , Al 2 O 3 , Fe 2 O 3 , CaO, K 2 O and MgO concentrations was done on soils from three different locations in Abraka Town the soil samples collected were dried, ground and sieved using colorimetric determinations, flame photometric and titration methods. At the different locations, the concentration of SiO 2 ranges from 448.50-179.40 ppm, 74.75-14.50 ppm and 299.00-29.90 ppm. Al 2 O 3 range from 35424.42-1653.1.39 ppm, 54679.07-23616.28 ppm and 35424.42-18893.02 ppm. Fe 2 O 3 from 37.30-6.66 ppm, 19.98-11.32 ppm and 21.31-10.67 ppm CaO from 112177.94-15871.18 ppm, 103395.73-28044.49 ppm and 12339.73-39262.28 ppm. K 2 O from 5184.35-1135.26 ppm, 5827.62-1865 ppm and 4276.15-1173.10 ppm and MO from 2800-9800 ppm. It is found that the concentration of CaO is higher in three different locations followed by the concentration of Al 2 O 3 . Fe 2 O 3 have the least concentration in one different location. Therefore, it can be said that the amount of CaO in ant-hill soils would support the shape and resistance of the cast to rain. It is of mite that CaO in a major constituent in cement and when hard stone reacted with water forms-like mass.
