  • A Research on the Behavior of a Polyurethane Polymer Waterproof Material Used in Bridge Geotechnical Applications
  • Abstract Polyurethane is enjoying a widespread use as a polymer-based waterproof material in civil engineering In the present study we consider a temperature-sensitive waterproof and moisture-permeable polyurethane material (PTPE-PU) characterized by one or more phase transition temperatures (critical temperatures). Near the critical temperature, the waterproof and moisture permeability of polyurethane undergo abrupt changes. The related stability, thermal performance, water resistance, hydrostatic pressure, and moisture permeability are investigated here considering a PTPE-PU traditionally used in bridge geotechnical engineering. The results show that the moisture permeability of the coated bridge rock and soil undergo sudden variations near the crystallization and melting temperature of… More

  • Analysis of Highway Asphalt Modified with Recycled Rubber and Waste Plastics
  • Abstract In this study, it is shown how recycled rubber and waste plastics can modify the softening point and penetration of asphalt traditionally used for highways. It is shown that the modified asphalt can meet the performance index requirements when the components are present with a certain proportion or relative ratio (1:3.5). The dispersion process of the masterbatch in base asphalt can effectively be implemented, with good results and a smaller mixing time. The proposed approach may be regarded as a good strategy to achieve energy savings and protection of the environment. More

  • Study on the Thermal Performances of a New Type of Fabricated Thermally Insulating Decorative Wall Material
  • Abstract This study proposes three possible keel-surface layer combinations to implement a new type of thermally insulating decorative wall system. A set of 8 samples has been studied. In particular, through theoretical calculations, simulations, and experimental verification, the influence of different types of connecting structures on the overall thermal performance of the wall system has been determined. It has been found that a proper combination of these elements can meet existing energy-saving standards and effectively reduce the energy loss caused by thermal bridges due to the installation of steel keels at the edges of integrated wall panels.

  • Synthesis of a Novel TiO2@Ag3PO4 Core-Shell Structure with Enhanced Photocatalytic Performance
  • Abstract Ag3PO4 exhibits a high photocatalytic activity if exposed to visible light, however, it displays bottlenecks such as poor cycle-stability and mediocre ability to degrade methyl orange (MO) because of limited adsorption of MO molecules onto its surface. In this study, nano TiO2 prepared by a one-step method was combined with Ag3PO4 to form a TiO2@Ag3PO4 heterojunction in order to improve this material both in terms of photocatalysis and photostability. After adding a KH-570 silane coupling agent, the photocatalytic performance of TiO2@Ag3PO4 could be improved even further, with the degradation rate of MO maintained at more than 90% after three cycles… More

  • A Study on a Magnesium-Based Layered Composite Used as a Flame Retardant for Phenolic Epoxy Resins
  • Abstract

    The effects of a magnesium-based layered composite on the flammability of a phenolic epoxy resin (EP) are studied. In order to produce the required composite material, first, magnesium hydroxide, aluminum salt and deionized water are mixed into a reactor according to a certain proportion to induce a hydrothermal reaction; then, the feed liquid is filtered out using a solid-liquid separation procedure; finally, the material is dried and crushed. In order to evaluate its effects on the flammability of the EP, first, m-phenylenediamine is added to EP and vacuum defoamation is performed; then, EP is poured into a polytetrafluoroethylene mold, cooled… More

  • Study on the Deformation Mechanism of a Soft Rock Tunnel
  • Abstract The large deformation of soft rock tunnel is one of the key problems to be overcome in the tunnel construction stage. In the present study, the deformation mechanism of a representative tunnel and some related countermeasures are investigated using field tests and engineering geological analysis. Owing to the scarce performances of methods based on other criteria such as small pipe spacing, anchor bolt length and steel frame spacing, a new support scheme is implemented and optimized. Results show that shear failure and bedding sliding are produced under high horizontal stress conditions. The low strength of the surrounding rock results in… More
