Review ArticleOpen accessIn the abstractStudies on Environmental Impact Assessment of Reinforced Concrete in Different Life Cycle PhasesJair Frederico Santoro, Moacir KripkaConcrete is one of most used materials in construction and also one of the main responsible for the emission of carbon dioxide, or CO2, in the atmosphere. Thus, in order to study ways to reduce this impact, it is important to evaluate the influence of each raw material of the reinforced concrete, as well as the phases of the life … …International Journal of Structural Glass and Advanced Materials Research, Vol. 1, Issue 2 · 2 Jan 2018 · 8,218 accessesView PDFCite
Research ArticleOpen accessIn the abstractDynamic Solution Code for Structural Analysis upon Joint ElementS. A. Sadrnejad, M. LabibzadehThe analysis of large structures mostly requires a complete three dimensional finite element discretization. Stability of such structures includes not only the stability of structure itself but also that of foundation as well as interconnection elements. The general instability of a structure may be affected by two aspects, firstly, an inappropriate preliminary classical design of the structure and inadequate control … …Journal of Computer Science, Vol. 2, Issue 5 · 31 May 2006 · 6,446 accessesView PDFCite
Research ArticleOpen accessIn the abstractUsing Crump Rubber (CR) of Scrap Tire in Hot Mix Asphalt DesignOmar Asad AhmadHot Mix Asphalt (HMA) design is one of the most important types of pavement used in highway construction. This research provided a hot mixture design method modifying with Crump Rubber Scrap Tire (CR) in order to develop and determining the optimum additive for hot mix asphalt design. All tests conducted to the raw material including specific gravity, compact test and … …American Journal of Applied Sciences, Vol. 14, Issue 2 · 13 Feb 2017 · 7,367 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvaluation of Interregional Freight Generation Modelling Methods by using Nationwide Commodity Flow Survey DataWirach HirunA trip generation model is one of the four parts of the classical transport planning model, which explores the volume of trip or freight at the originating and destination points of a traffic analysis zone. The process of calibrating a trip generation model needs appropriate data. Freight transport data are always robust and a powerful calibration technique is required to … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 3 · 18 Aug 2016 · 8,113 accessesView PDFCite
Research ArticleOpen accessIn the abstractUncertainty Impact of the Effective Diffusion Coefficient on the Concrete Chemical DegradationA. BadaouiReinforced concrete is the construction material widely used in civil engineering. However, knowledge of its long-term performance and the uncertain impact of the environment on his behaviour make it difficult to accurate assessment of the durability of structures with time. When a structure is put into service, it is likely to damage, which origin can be physical, mechanical or chemical. … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 3 · 23 Jul 2015 · 7,762 accessesView PDFCite
Research ArticleOpen accessIn the abstractDEVELOPMENT OF ARCHIMEDEAN’S PIPE-SCREW FOR THAI SAIL WINDPUMPRonnakorn Thepwong, Issaree Hansacharoonroj, Joseph Khedari et al.This study describes new considerations in the design and development of Archimedean’s Pipe-Screw especially for water pumping in case of low head high volume form open farm pond at Rajamangala University of Technology Rattanakosin, Thailand. The objectives of this research is to develop an Archimedean’s Pipe-Screw especially for water pumping in case of low head high volume form open farm … …American Journal of Environmental Sciences, Vol. 10, Issue 3 · 22 Apr 2014 · 7,359 accessesView PDFCite
Research ArticleOpen accessIn the abstractEFFECT OF USING STEEL SLAG AGGREGATE ON MECHANICAL PROPERTIES OF CONCRETESultan A. Tarawneh, Emhaidy S. Gharaibeh, Falah M. SarairehThis study presents an evaluation of the physical and mechanical properties and characteristics of steel slag aggregate concrete in comparison with the typical crushed limestone stone aggregate concrete. Hardened concrete consist of more than 70% aggregate due to the high demand in building construction and the increase of the amount of disposed waste material, suppliers and researchers are exploring the … …American Journal of Applied Sciences, Vol. 11, Issue 5 · 10 Feb 2014 · 8,063 accessesView PDFCite
Research ArticleOpen accessIn the abstractMEASUREMENT OF RADON EXHALATION RATE, RADIUM ACTIVITY AND ANNUAL EFFECTIVE DOSE FROM BRICKS AND CEMENT SAMPLES COLLECTED FROM DERA ISMAIL KHANNisar Ahmad, Mohamad Suhaimi Jaafar, Sohail Aziz Khan et al.Radon concentration, exhalation rate, radium activity and annual effective dose have been measured from baked and unbaked bricks and cement samples commonly used as construction material in the dwellings of Dera Ismail Khan City, Pakistan. CR-39 based NRPB radon dosimeters and RAD7 have been used as passive and active devises. The values of radon concentration for baked, unbaked bricks and … …American Journal of Applied Sciences, Vol. 11, Issue 2 · 21 Dec 2013 · 8,285 accessesView PDFCite
