  • A Taguchi approach for optimizing the mixture design of cold-bonded PCM aggregates
    Erman Yiğit Tuncel, Bekir Yılmaz Pekmezci
    Energy Sources Part A Recovery Utilization and Environmental Effects, 2024
    Energy efficiency and waste recovery have vital importance for a sustainable environmental progress. This study contributes to both issues considering three different aspects which are (i) production of an energy-efficient building material, (ii) utilization of waste materials inside the produced composites, and (iii) use of an eco-friendly production method. The first part of the research explains the design, optimization, and performance of cold-bonded lightweight aggregates. By-products such as fly ash (FA), ground granulated blast furnace slag (GGBS) were utilized to manufacture these aggregates. Taguchi method was employed in the experimental design of the aggregate composition. Factors influencing the engineering properties of aggregates and their contribution ratios were investigated using analysis of variance (ANOVA). Binder composition was found to be the most important factor influencing physical properties, while the curing time was the dominant factor effecting the strength of the aggregates. Optimal values of the factors were determined, and in the second part of the research, aggregate mixture design was enhanced using a microencapsulated phase change material (PCM) for a better thermal performance. The effect of different PCM ratios to the engineering properties of the produced pellets was studied experimentally.
  • Performance of glass fiber-reinforced cement composites containing phase change materials
    Erman Yiğit Tuncel, Bekir Yılmaz Pekmezci
    Environmental Progress and Sustainable Energy, 2019
    The use of solar energy has become a promising method to reach energy efficient solutions throughout the last century. Improving the thermal properties of building members will contribute to the efficient use of energy by preventing heat gain/loss through the building envelope. Phase change materials (PCMs) are favorable materials for thermal applications because of their large contribution to the thermal mass of a building and thus providing “inertia” against temperature fluctuations. In this experimental study, glass fiber‐reinforced cementitious composites were modified using a commercial microencapsulated PCM to improve their thermal performance. The thermal and the mechanical performances of the composites were investigated. With the use of PCMs, the latent heat capacity of the composites increased while the thermal conductivity decreased. Conversely, the mechanical properties of composites declined with increases in PCM amount. The main conclusions of the experimental study are as follows: PCMs provide a great potential to fiber‐reinforced cementitious composites to support the efficient use of energy, thereby enhancing the thermal features of the composites. The performance of PCM composites shows a serious variation according to different service temperatures. Therefore, the effect of service temperature must be considered particularly with respect to safe utilization of these materials. © 2018 American Institute of Chemical Engineers Environ Prog, 38:e13061, 2019

  • Fiber quantity analysis of cementitious composite using multifocus imagery

    Polymer Composites, 2018
    After static and impact loading tests applied to PVA fiber reinforced cementitious composites, depending on the loading type and mixture properties of the composite, different fiber failure types are observed at the fractured surface of test samples. It is very hard to determine the pulled out fiber amount with conventional methods. The purpose of this study is to display these differences in a quantitative way using digital imaging processing techniques and exhibit the relation between absorbed energy and pulled out fiber area. Digital image processing might provide useful techniques to determine structure of the cracked surface of samples. Since close‐up images of the failure surfaces of test samples are needed to examine thin and short fibers, from the point view of science of measurement and modeling from stereo images, digital photogrammetry does not produce prospective results appropriately. In this work, in order to reveal fibers, two complementary image‐processing techniques were used successively. First, images, which obtained from macro photographic lenses at different focal lengths, were combined with multifocus imaging. Second, processed multifocused image is automatically clustered in order to extract fibers with maximum likelihood classification algorithm. Consequently, state of side‐views of the fractured surfaces of composites is drawn precisely. The amount of pulled out fibers were estimated by using the area calculated. The relation between the absorbed energy and pulled fiber area was obtained. With increase of absorbed fracture energy, pulled out fiber amount for both static and dynamic tests increases. POLYM.

  • Behavior of PVA fiber-reinforced cementitious composites under static and impact flexural effects
    Hakan Nuri Atahan, Bekir Yılmaz Pekmezci, Erman Yiğit Tuncel
    Journal of Materials in Civil Engineering, 2013
    The effects of fiber volume fraction and matrix properties on the mechanical performance of 15-mm thick short cut PVA (polyvinyl alcohol) fiber-reinforced cementitious composites were investigated experimentally. Fiber volume ratios of mixtures varied between 0.5 and 2.0% by volume. Two different water to cement ratios (w/c) have been used (0.25 and 0.35) for matrix production. Test results have shown that both fiber content and matrix strength have significant effects on flexural behavior and impact resistance of these composites. The combined effect of w/c and fiber volume fraction on impact resistance was more drastic compared with specific fracture energies of composites determined under static loads. Especially under the effects of impact loads, higher values of w/c and increased PVA fiber content significantly improved the energy absorption capacity of these composites.
