Good Practices in Urban Water Management: Decoding Good Practices for a Successful Future
Author: ed. by Anand Chiplunkar, Kallidaikurichi Seetharam, Cheon Kheong Tan | Size: 5 MB | Format:PDF | Quality:Original preprint | Publisher: ADB, National University of Singapore | Year: 2012 | pages: 228 | ISBN: 9789290927419
This report presents case studies on successful Asian water utilities. The case studies provide objective, accurate, and critical analyses of urban water management practices in eight Asian cities over a 10-year period.
Other local leaders throughout the developing world can use these cases to help craft their own solutions, taking into account specific local circumstances. What is most important for cities is to find some common base elements for success and then replicate these, albeit with appropriate modifications, to suit their own special conditions.

A mechanistic study explaining the synergistic viscosity increase obtained from polyethylene oxide (PEO) and β-naphthalene sulfonate (BNS) in shotcrete
Author: J. Pickelmann, J. Plank | Size: 1.2 MB | Format:PDF | Quality:Original preprint | Publisher: Cement and Concrete Research Vol 42, Iss 11 | Year: November 2012 | pages: 1409–1416 | ISSN: 0008-8846
In shotcrete, a combination of polyethylene oxide (PEO) and β-naphthalene sulfonate (BNS) is commonly applied to reduce rebound. Here, the mechanism for the synergistic viscosity increase resulting from this admixture combination was investigated via x-ray diffraction (XRD), infrared and nuclear magnetic resonance (NMR) spectroscopy. It was found that the electron-rich aromatic rings present in BNS donate electrons to the alkyl protons of PEO and thus increase the electron density there. This rare interaction is known as CH–π interaction and leads to the formation of a supramolecular structure whereby PEO chains bind weakly to BNS molecules. Through this mechanism a polymer network exhibiting exceptionally high molecular weight and thus viscosity is formed. Among polycondensates, sulfanilic acid–phenol–formaldehyde (SPF) provides even higher synergy with PEO than BNS while melamine (PMS), acetone (AFS) or polycarboxylate (PCE) based superplasticizers do not work at all. Effectiveness of lignosulfonates is dependent on their degree of sulfonation.

Mix proportion of eco-friendly fireproof high-strength concrete
Author: Se Jin Choi, Soo-Hwan Kim, Su-Jin Lee, Rosa Won, Jong-Pil Won | Size: 0.94 MB | Format:PDF | Quality:Original preprint | Publisher: Construction and Building Materials, Vol 38 | Year: January 2013 | pages: 181–187 | ISSN: 0950-0618
The optimum mix proportion for eco-friendly fireproof high-strength concrete was derived in this study. The mixture of the concrete was evaluated by thermal performance through a fire-resistance test. To derive the optimum mix proportion, ground granulated blast-furnace slag and porcelain were substituted, and a 0.1 vol.% fraction of polypropylene fibre was added to prevent spalling. Porcelain was used, as it is effective in improving residual strength. The RABT curve was adopted as the heating time–temperature curve for the fire-resistance test. The derived optimum mix proportion can contribute to ecological friendliness, as it produced up to 34.6% CO2 savings compared with the mixture using conventional cement. Furthermore, improvement in the characteristics of concrete was shown after exposing this mixture to high temperature following the addition of porcelain.

Deterioration Mechanism of Cementitious Materials Under Acid Rain Attack
Author: Meng-Cheng Chenn, Kai Wang, Li Xie | Size: 2.38 MB | Format:PDF | Quality:Original preprint | Publisher: Engineering Failure Analysis | Year: September 2012
Cementitious material specimens were immersed in a simulated acid rain solution for different time periods to allow deterioration to occur and then the specimen strengths were measured and the mineralogical compositions and microstructures were analyzed using X-ray diffraction (XRD), Fourier Transform infrared (FT-IR) spectroscopy, scanning electron microscopy (SEM) and energy dispersive X-ray (EDX) diffraction.

[REQUEST] State-of-the-arts of research on aluminum alloy structures
Size: ?? MB | Format:PDF | Quality:Unspecified

Abstract：
Aluminum alloy structures are widely used in the world due to their special advantages,and more than 10 large aluminum alloy space structures have been constructed in China up to now.This paper provides a state-of-the-art review report on research on aluminum alloy structures related to material property,basic structural members,connection behaviors and structural system.In generally,the research work on aluminum alloy structures in many developed countries is relatively matured,especially for different basic structural members.While in China,such studies on aluminum alloy structures are being carried out more and more widely and deeply recently,most of which are focused on axially-compressed members,and no reliability analysis for aluminum alloy structures is conducted,mainly due to the lack of experiment data for statistic analysis.Therefore,it is very necessary to establish an experimental database for domestic aluminum alloy structures as a basic step to reliability analysis.
