Research ArticleOpen accessIn the keywordsThe Use of Nano Silica for Improving Mechanical Properties of Hardened Cement PasteIntisar Kuli, Taher M. Abu-Lebdeh, Elham H. Fini, Sameer A. HamoushThe influence of adding Nano particles of silicon dioxide (SiO2) on cement pastes was studied for both water and vacuum curing methods. Specimens made up of different percentage of Nano Silica were tested at different ages ranging from 3-56 days. The effect of (5-20 nm) Nano-Silica on the strength development of Nano-cement was determined using Material Tests System (MTS). The … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 1 · 13 Mar 2016 · 9,084 accessesView PDFCite
Research ArticleOpen accessIn the keywordsBasalt 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 PDFCite
Research ArticleOpen accessIn the keywordsUse of Recycled Aggregate and Fly Ash in Concrete PavementMyle Nguyen James, Wonchang Choi, Taher Abu-LebdehProblem statement: Recycled materials aggregate from the demolished concrete structures and fly ash from burning coal shows the possible application as structural and non structural components in concrete structures. This research aims to evaluate the feasibility of using concrete containing recycled concrete aggregate and fly ash in concrete pavement. Approach: Two water cement ratio (0.45 and 0.55) the compressive strength, … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 2 · 12 Jul 2011 · 9,309 accessesView PDFCite
Research ArticleOpen accessIn the keywordsExploring the Reuse Potential of Chemical Sludge from Textile Wastewater Treatment Plants in India-A Hazardous WasteHema Patel, Suneel PandeyProblem statement: This study was conducted to explore the reuse potential of the chemical sludge (considered as hazardous waste as per Indian Government Hazardous Waste Management Rules) generated from combined effluent treatment in textile clusters. These textile clusters mainly cover the cotton dyeing and printing operations. Approach: Therefore, treatability studies of chemical sludge were conducted using solidification/stabilization treatment to examine … …American Journal of Environmental Sciences, Vol. 5, Issue 1 · 28 Feb 2009 · 8,539 accessesView PDFCite
Research ArticleOpen accessIn the keywordsBehavior of Stabilized Peat Soils in Unconfined Compression TestsWong Leong Sing, Roslan Hashim, Faisal Haji AliProblem statement: Deep stabilized peat columns were known to be economical at forming foundations to support highway embankments constructed on deep peat land. However, failure in the formation of the columns with adequate strength was often attributed to unsuitable type and insufficient dosage of binder added to the soil. Organic matter in peat was known to impede the cementing process … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 4 · 31 Dec 2008 · 7,452 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEffect 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
