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 keywordsThe Use of the Super Absorbent Polymer as Water Blocker in Concrete StructuresMoayyad Al-Nasra, Mohammad Daoudb, Taher M. Abu-LebdehAdding super absorbent polymer to the concrete mix improves the performance of the concrete in its both stages; fresh concrete and hardened concrete. The super absorbent polymer has the ability to absorb relatively large amount of water and convert it into gel at the same time the volume increases proportionally. The new modified concrete has the ability to retain water … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 4 · 6 Nov 2015 · 8,932 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEffect of Polypropylene Fibers on the California Bearing Ratio of Air Cured Stabilized Tropical Peat SoilBehzad Kalantari, Bujang B.K. Huat, Arun PrasadProblem statement: Peat soil is well known to deform and fail under a light surcharge load and is characterized with low shear strength, high compressibility and high water content. With the rising demand from the construction industry, utilization of these soils is required and suitable technique needs to be found out for stabilizing them. Approach: Model study had been carried … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 1 · 31 Mar 2010 · 8,697 accessesView PDFCite
Research ArticleOpen accessIn the keywordsSynthesis and Characterization of Bio-based Polyurethane PolymersJahangir Emrani, Ramazan Benrashid, Shahrzad Mohtarami et al.This paper describes the development of new biobased Polyurethanes (PU) starting from swine manure bio-resin and diisocyanates. The bio-resin is produced from swine manure via a hydrothermal process. For sustainability, today, many PUs in new specialized applications, are biobased. In this study, different commercial diisocyanates including MDI, Desmodur W, Desmodur H and Demodur I and swine manure, which is an … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 4 · 28 Nov 2018 · 8,361 accessesView PDFCite
Research ArticleOpen accessIn the keywordsRole of Plasmid in Production of Acetobacter Xylinum BiofilmsAbbas Rezaee, Sanaz Solimani, Mehdi ForozandemogadamAcetobacter xylinum has the ability to produce cellulotic biofilms. Bacterial cellulose is expected to be used in many industrial or biomedical materials for its unique characteristics. A. xylinum contains a complex system of plasmid DNA molecules. A 44 kilobases (kb) plasmid was isolated in wild type of A. xylinum. To improve the cellulose producing ability of A. xylinum, role of … …American Journal of Biochemistry and Biotechnology, Vol. 1, Issue 3 · 30 Sep 2005 · 7,498 accessesView PDFCite
