This paper attempts to study the mechanicalbehaviour of coconut shell aggregate (CSA) concretesubjected to elevated temperatures when coconut shell (CS)is used to replace coarse aggregate at 0, 10, 20 and 40% inconcrete. The coconut shell used was obtained by breakingthe shells into smaller sizes of less than 20mm after thefibres were removed. In order to produce control concretesamples with a minimum compressive strength of 15N/mm2at 28 days curing age, mix ratio of 1:2:4 and water-cementrat...
This paper presents the findings of an investigation into the use of mahogany leaves particles for the production of gumArabic bonded particleboards. Fresh mahogany leaves, air-dried to a target moisture content of 10% were crushed to anaverage particle size of 2mm. Mix ratios of 2:1, 2.5:1, 3:1, and 3.5:1 of gum Arabic to the crushed mahogany leaves byweight of the mahogany leaves were produced respectively. Twenty four (24) particleboards of sizes 200mm length,50mm width, and 6mm thick were...
This paper presents the findings of an investigation on the use of coconut shell ash (CSA) as admixture in concrete and its effect on durability performance. The CSA used was obtained by controlled burning of coconut shell in an incinerator to a temperature of 600–650ºC for 3 hours, air cooled, sieved through 75μm sieve and characterized by using X-ray Fluorescence (XRF) analytical method. The compressive and splitting tensile strengths of concrete were investigated at varying CSA additio...
This paper presents the findings of an investigation on coconut shell ash (CSA) as admixture in cement paste and concrete. The CSA used was obtained by controlled burning of coconut shell in an incinerator to a temperature of between 600–650ºC for 3 hours, air cooled, sieved through 75μm sieve and characterized based on its oxides composition determined using X-ray Fluorescence (XRF) analytical method. The effects of CSA on cement paste were investigated with addition of 0, 2, 4, 6, 8 and...
Correlation and regression in this paper were employed as analytical tools to study the degree of relationship as well asthe nature and strength of the relationship between green concrete properties and percentage replacement of cementwith civil engineering materials. Pearson product-moment method and Spearman’s correlation coefficient wereextensively used to show how correlation analysis can be practically applied in green concrete research. Least squareregression line method for both line...

ABSTRACTThe main aim of any electric power supply in the world is to provide uninterrupted power supply at all times to all its consumers. Although, in developing countries, the electric power generated to meet the demands of the growing consumers of electricity is insufficient, hence power instability and outage.Power instability or outage in general does not promote development in the public and private sector. The investors do not feel secure to come into a country with constant or frequen...
