Optimization of Compressive Strength of Snail Shell Ash Blended Cement Concrete
Abstract: In this paper, a mathematical model is developed to optimize the compressive strength and the corresponding values of the mixture proportions of snail shell ash blended cement concrete using Scheffe’s regression method.A computer program written in qbasic language was invoked to quicken the selection of the cheapest mix ratios and the corresponding value of compressive strength of concrete. The mix ratio that optimized the compressive strength was found to be …

Maximizing Void Properties from Optimized Local Pozzolans in Wearing Course of Bituminous Concrete Mixtures
Abstract: Failure of asphalt pavement has influenced research into better ways to optimize local pozzolans seenas waste and reduce cost of importation of admixtures. Waste Shell Ashes are checked as localassembled by incorporating them in asphalt concrete mix design. Different research has shown thatsome agricultural waste/by-products can be admitted as mineral fillers in hot-mix asphalt concrete toobtain certain desirable properties. It is on this basis that this research attempts to interrogate …

POLYCYCLIC AROMATIC HYDROCARBONS (PAHs) AND HEAVY METALS IN SELECTED DRIED SEA FOODS FROM PORTHARCOURT CITY NIGERIA
Abstract: Polycyclic aromatic hydrocarbons (PAHS) and heavy metals constitute environmental recalcitrant pollutants which are toxic and carcinogenic. The levels of PAHs and heavy metals (As, Hg, V, Zn, Pb, and Cr) in dried sea foods: prawn (Panaeus monodon), water snail (Bithynia tentaculata), periwinkle (Littorina littorea), conch (Lobatus gallus) and Oyester (Ostrea edulis) were determined. PAHs were determined using GC/FID and the heavy metals were determined using AAS. Total PAHs ranged from …
