Research ArticleOpen accessPhrase in the titlePorosity Investigation of Kosova's ClayMakfire Sadiku, Naim Hasani, Altin MeleProblem statement: Acid activated clay minerals are used as catalysts in the desulphurization of crude oil or as catalyst carrier, drilling mud, bleaching earth. Approach: The efficiency of the acid activation can be described in two ways. As increase of the surface and as increase of the cumulative pore volume after the activation. Results: In different samples of the clay … …American Journal of Applied Sciences, Vol. 8, Issue 11 · 23 Sep 2011 · 7,502 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEffect of Various Combustible Materials on Insulating Properties of Refractory BricksIsiaka Olajide Odewale, Ebere Monica Ameh, Victor Tyonenge Dhave Amaakaven et al.The effect of various combustible materials on insulating properties of refractory bricks produced from Enugu fire clay and Ekebedi clay has been studied. This is aimed at determining the most favourable combustible material for different composition(s). The clays with combustible materials were used to compose different samples labeled A-G with varying percentages of combustible materials at reducing rate of 5% … …International Journal of Structural Glass and Advanced Materials Research, Vol. 4, Issue 1 · 22 Jul 2020 · 6,046 accessesView PDF Cite

Research ArticleOpen accessIn the abstractBasalt as Pozzolana and Filler in Ordinary Portland CementH. El-Didamony, I.M. Helmy, Randa M. Osman, A.M. HabboudPozzolana is defined as a siliceous or siliceous and aluminous materials which in itself possess little or no cementing properties, but will in a finally divided form and in the presence of moisture react with Ca(OH)2 at ordinary temperature to form compound possessing cementious properties. Pozzolanic cement contains Portland cement as one of their main components in addition to natural … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 2 · 24 Jun 2015 · 7,904 accessesView PDF Cite

Research ArticleOpen accessIn the abstractNumerical Investigation of Incompressible Fluid Flow through Porous Media in a Lid-Driven Square CavityM.A. Mohd Irwan, A. M. Fudhail, C.S. Nor Azwadi, G. MasoudProblem statement: Investigation of fluid flow behavior through porous media in a liddriven square cavity. Approach: The Brinkman-Forcheimer equation is coupled with the lattice Boltzmann formulation to predict the velocity field in the system. Three numerical experiments were preformed with different values of Darcy number to investigate the effect of porosity on the fluid flow. Results: In the current study, … …American Journal of Applied Sciences, Vol. 7, Issue 10 · 31 Oct 2010 · 7,405 accessesView PDF Cite

Research ArticleOpen accessIn the abstractPerformance Assessment and Monitoring of a Permeable Reactive Barrier for the Remediation of a Contaminated SiteValerio Zolla, Rajandrea Sethi, Antonio Di MolfettaThe present study illustrates the long-term monitoring plan carried out in order to investigate the performance of a zero-valent iron permeable reactive barrier (PRB) at a chlorinated solvents’ site. The cleanup intervention has been undertaken at an industrial landfill located near the city of Turin (Italy) and represents the first full-scale application of this technology in Italy. The monitoring plan … …American Journal of Environmental Sciences, Vol. 3, Issue 3 · 30 Sep 2007 · 7,438 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordExperimental Investigation of Thermo-Physical Properties of Soil Using Solarisation TechnologyAhmed Abed Gatea Al-Shammary, Abbas Kouzani, Akif Kaynak et al.Soil Thermo-Physical Properties (TPP) depend on heat transfer in the soil. This paper presents a study on different soil solarisation technologies influenced by soil TPP. This study evaluates three factors: The tillage depth for soil at three levels (15, 25 and 45 cm), the number of plastic film at three levels (single, double and without plastic film) and three cases … …American Journal of Applied Sciences, Vol. 14, Issue 7 · 17 Jul 2017 · 7,957 accessesView PDF Cite
