Research ArticleOpen accessEvery word in the titleStudy of the Permeability of Foam Conditioned Soils with Laboratory TestsLuca Borio, Daniele PeilaProblem statement: EPB tunneling requires that the excavated soil has a plastic and pulpy behavior to be able to apply a stabilizing pressure to the face, but it should also be impervious to counteract filtration forces that could develop ahead of the face. The evaluation of this parameter in granular soil, before and after conditioning, is therefore of key importance … …American Journal of Environmental Sciences, Vol. 6, Issue 4 · 31 Aug 2010 · 8,459 accessesView PDFCite
Research ArticleOpen accessIn the keywordsChloride Penetration Resistance Studies on Concretes Modified with Alkali Resistant Glass FibersK. Chandramouli, P. Srinivasa Rao, N. Pannirselvam et al.Problem statement: This research study presented the durability performance of glass fibre reinforced concrete. Approach: The influence of fiber content on the durability performance of glass fibre reinforced concrete specimens having different percentage of glass fibres with varying grades of concrete were investigated. Results: The parameter of investigation included rapid chloride permeability test for a period of 365 days. Specimens … …American Journal of Applied Sciences, Vol. 7, Issue 3 · 31 Mar 2010 · 7,253 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEvaluation of Damsites Groutability Using Secondary Permeability Index, Rock Classification (Case Studies)R. Ajalloeian, F. MoeinProblem statement: The dam body and foundation seepage is one of the important points in design parameters. This index is related to the permeability. There fore permeability is one of the basic parameter in design grout curtain, prevent water escape from foundation and avoid negative seepage pressure in borrow materials, so grouting is used. Grouting means injected materials like cement … …American Journal of Applied Sciences, Vol. 6, Issue 6 · 30 Jun 2009 · 7,411 accessesView PDFCite
Research ArticleOpen accessIn the abstractDevelopment of Roofing Tiles Support Made from Bituminous PlywoodOuro–Djobo Samah, Sinko Banakinao, Komlan Lolo, Kodjo AttipouIn this study, a new design of roof support was investigated to improve the system of roof coverings with roofing tiles. Usually, wood frames or slabs are often used as support for roofing tiles, which presents many disadvantages such as the expensive cost of the slabs and sometimes inefficient Corresponding wood frames. The new design proposed in this study uses … …American Journal of Applied Sciences, Vol. 19, Issue 1 · 19 Sep 2022 · 6,370 accessesView PDFCite
Research ArticleOpen accessIn the abstractAssessing and Improving the Performance of Grouted MacadamMomtaz M. Othman, Ahmed Ebrahim Abu El-Maaty, Zeinab S. HusseinThere are many road defects appear in flexible pavement layers. Rutting, raveling and cracks are considered the main problems in Egypt. Using grouted macadam system as a surface asphaltic layer (or called Semi-Flexible Pavement (SFP)) has many advantages such as saving the natural asphalt and enhancing the performance against deteriorations. The main scope of this research is to evaluate and … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 2 · 29 Apr 2020 · 7,078 accessesView PDFCite
Research ArticleOpen accessIn the abstractMeasuring Hydraulic Conductivity Using Geotechnical CentrifugeNur Aishah Zarime, Wan Zuhairi Wan YaacobThis study investigated the validity of hydraulic conductivity value using Mini Column Infiltration Test. Granitic residual soils from Broga Selangor, Malaysia were tested to obtain the hydraulic conductivity value in relatively shorter time. Soil samples were physically characterized before being tested using Centrifuge Mini Column Infiltration Technique. A normal 1-g Falling Head Permeability Test (Kf) was also being performed as … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 4 · 6 Nov 2017 · 7,775 accessesView PDFCite
Research ArticleOpen accessIn the abstractAssessment of Strength Development in Stabilized Soil with CBR Plus and Silica SandSeyedesmaeil Mousavi, Aliakbar KaramvandThis paper investigates the potential use of a nano polymer stabilizer, namely CBR PLUS for stabilization of soft clay and formulation of an optimal mix design of stabilized soil with CBR PLUS and silica sand. The highway settlements induced by the soft clay are problematic due to serious damages in the form of cracks and deformation. With respect to this, … …American Journal of Applied Sciences, Vol. 15, Issue 4 · 12 Apr 2017 · 7,889 accessesView PDFCite
Research ArticleOpen accessIn the abstractStrength, Chloride Permeability and Corrosion of Coarse Fly Ash Concrete with Bagasse-Rice Husk-Wood Ash AdditiveVeera Horsakulthai, Kittichat PaopongpaiboonThis study studied the utilization of Bagasse-Rice Husk-Wood Ash (BRWA) as an additive for improving the strength and durability of coarse Fly Ash (FA) concrete. The ground BRWA was used as an additive for maintaining the consistent slump of FA concrete. The strength, chloride permeability and corrosion resistance were investigated. The chloride permeability of concrete was evaluated using the measurement … …American Journal of Applied Sciences, Vol. 10, Issue 3 · 14 Mar 2013 · 6,928 accessesView PDFCite
Research ArticleOpen accessIn the abstractNumerical Modeling of Periodic Pumping Tests in Wells Penetrating a Heterogeneous AquiferPeter A. Fokker, Joerg Renner, Francesca VergaThis study investigated how to utilize multiple frequency components of pressure data from periodic pulse tests to estimate the intra-well permeability and compressibility distribution and also the presence of heterogeneities in a real field case. Periodic well testing is a technique in which injection or production pulses of a fluid are applied to a well in a periodic fashion. One … …American Journal of Environmental Sciences, Vol. 9, Issue 1 · 13 Jan 2013 · 7,990 accessesView PDFCite
Research ArticleOpen accessIn the abstractRemediation of Diesel Contaminated Soils Using Surfactants: Coulumn StudyE. Salehian, A. Khodadadi, B. HosseiniThis study presents the experimental remediation studies of diesel contaminated soil with Sodium Deducible Sulfate (SDS) as surfactants using column tests. Sandy selected soil had the grain size distribution of # 40 meshes to the # 200 mesh range. The soil columns were contaminated with adequate diesel amount to achieve the concentration of 10000 and 20000 ppm in soil. 0.1, … …American Journal of Environmental Sciences, Vol. 8, Issue 4 · 18 Jun 2012 · 8,320 accessesView PDFCite
