Research ArticleOpen accessIn the abstractExperimental Investigation on Geomechanical Properties of Tropical Organic Soils and PeatBujang B.K. Huat, Afshin Asadi, Sina KazemianProblem statement: Organic soils and peat were believed to be geotechnically problematic due to their very high compressibility, very low shear strength and difficult accessibility. Although conventional soil mechanics theory could be applied to the soils, it was found that important anomalies existed which required special considerations. Correlations between geomechanical parameters for the soils were known to be important for … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 1 · 31 Mar 2009 · 10,172 accessesView PDFCite
Research ArticleOpen accessIn the abstractHeavy Metal Mobility in Polluted Soils: Effect of Different TreatmentsMarta Susana Zubillaga, Emiliano Bressan, Raúl Silvio LavadoThe effects of biosolid compost and phytoremediation applied on the leaching of cadmium, copper, lead and zinc, through the different horizons of a superficially polluted soil were determined. The soil was from the Province of Buenos Aires, Argentina. It was contaminated with cadmium copper, lead and zinc. Leaching columns were used with three different horizons: A: 0.12 m A horizon, … …American Journal of Environmental Sciences, Vol. 4, Issue 6 · 31 Dec 2008 · 7,132 accessesView PDFCite
Research ArticleOpen accessIn the abstractSimple Method of Purifying Humic Acids Isolated from Tropical Hemists (Peat Soil)Susilawati Kasim, Osumanu Haruna Ahmed, Nik Muhamad Ab. Majid, Mohd Khanif YusopThe objectives of this study were: To investigate whether a purification period of HA isolated from Hemists peat soils could be reduced and to investigate whether distilled water could be used to purify HA isolated from Hemists peat soils. Standard procedures were used to extract and fractionate HA in a Hemists peat soil. The isolated HA was purified by suspending … …American Journal of Applied Sciences, Vol. 5, Issue 12 · 31 Dec 2008 · 7,151 accessesView PDFCite
Research ArticleOpen accessIn the abstractEngineering Properties and Compressibility Behavior of Tropical Peat SoilYouventharan Duraisamy, Bujang B.K. Huat, Azlan A. AzizThis paper presents the engineering properties and compressibility behavior of various types of tropical peat soil collected from several locations in Malaysia. These soils represented fibric, hemic and sapric type of tropical peat with organic content ranging from 70% to 90%. The correlations of the various basic engineering properties of the tropical peat soils have been found to be close … …American Journal of Applied Sciences, Vol. 4, Issue 10 · 31 Oct 2007 · 8,570 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign and Performance of EPS Footing for Lightweight Farm Structure on Peat SoilMohammad Abdullah, Bujang B.K. Huat, Rezuwan Kamaruddin et al.The objective of this research project was to find a potential replacement for the conventional pile foundation principally for peat soil. It is fundamentally meant for lightweight and impermanent agricultural farm structures. Preceding the design and development of the foundation the physical characteristics of the in-situ peat such as; peat depth, soil consolidation, soil compressibility, water table, liquid limit, soil … …American Journal of Applied Sciences, Vol. 4, Issue 7 · 31 Jul 2007 · 7,239 accessesView PDFCite
Research ArticleOpen accessIn the abstractRelationship Between Shear Strength and Soil Water Characteristic Curve of an Unsaturated Granitic Residual SoilThamer Ahmed Mohamed, Faisal Hj. Ali, S. Hashim, Bujang B.K. HuatShear strength parameters are crucial for stability analyses of slopes against slope failures and landslides. The three shear strength parameters that are required to define a failure envelope of an unsaturated soil are c’ (apparent cohesion), Φ’ (effective angle of friction) and Φb (shear strength change with change in matric suction). A soil-water characteristic curve (SWCC) that relates the water … …American Journal of Environmental Sciences, Vol. 2, Issue 4 · 31 Dec 2006 · 7,350 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Chemical Admixtures on the Engineering Properties of Tropical Peat SoilsBujang B.K. Huat, Thamer A. Mohamed, Shukri MaailThis research describes a study on the effect of chemical (cement and lime) admixtures on the index and engineering properties (compaction and unconfined strength) of tropical peat soils. The ordinary Portland cement and hydrated lime were used. The amounts cement and lime added to the peat soil sample, as a percentage of the dry soil mass was in the range … …American Journal of Applied Sciences, Vol. 2, Issue 7 · 31 Jul 2005 · 8,472 accessesView PDFCite
Research ArticleOpen accessIn the abstractField and Laboratory Suction- Soil Moisture Relationship of Unsaturated Residual SoilsBujang B.K. Huat, Faisal H. Ali, A. AbdullahSoils located above the groundwater table such as residual soils are generally unsaturated and possess negative pore-water pressures. A soil-water (moisture) characteristic curve (SWCC) that relates the water content of a soil to matric suction is an important relationship for the unsaturated soil mechanics. The SWCC essentially shows the ability of an unsaturated soil to retain water under various matric … …American Journal of Environmental Sciences, Vol. 1, Issue 1 · 31 Mar 2005 · 7,038 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordEffect of Animal Manure Application Rates on Soil Moisture Conservation at, Somali Regional State, EthiopiaTekilil WoldeThe Ethiopian economy is mainly agrarian. It employs 85% of the population and contributes 45% of the gross domestic product and 90% of the national export earnings but agriculture in Ethiopia is dominated by rainfed farming with low productivity specially dry land part of the country like Somali region. As a result, crops have severe moisture stress through their growth … …American Journal of Agricultural and Biological Sciences, Vol. 14, Issue 1 · 15 Aug 2019 · 7,744 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordBioremediation of Petroleum Hydrocarbon-Polluted Mangrove Swamps Using Nutrient Formula Produced From Water Hyacint (Eicchornia crassipes)Frank Anayo Orji, Abiye Anthony Ibiene, Phillip O. OkerentugbaLaboratory-scale studies were carried out using a nutrient formula produced from Eicchornia crassipes plant to achieve bioremediation of crude oil impacted mangrove soil. In a 70 day study, the culturable heterotrophic bacterial population of the Eichhornia crassipes recipe increased from 6.26×105 Cfu/g to 2.69×107 Cfu/g. The control set-up had its total culturable bacterial count increased from 5.76×105 Cfu/g to 1.24×106 … …American Journal of Environmental Sciences, Vol. 9, Issue 4 · 28 Aug 2013 · 7,643 accessesView PDFCite
