    Effect of Alkaline Electrolyzed Water on Performance Improvement of Green Concrete with High Volume of Mineral Admixtures

    Guibin Liu1, Meinan Wang2, Qi Yu1, Qiuyi Li2, Liang Wang2,*

    Journal of Renewable Materials, Vol.9, No.11, pp. 2051-2065, 2021, DOI:10.32604/jrm.2021.015398

    Abstract The strength and durability of concrete will be significantly reduced at high volume of mineral admixture, and the poor early strength of concrete also still needs to be solved. In this investigation, a highly active alkaline electrolyzed waters was used as mixing water to improve the early strength and enhance the durability of green concrete with high volume mineral admixture, the influences of alkaline electrolyzed water (AEW) on hydration activity of mineral admixture and durability of concrete were determined. The results showed that compared with natural tap water, AEW can accelerate early hydration process of cement in concrete and produce… More > Graphic Abstract

    Journal of Renewable Materials, Vol.9, No.5, pp. 959-977, 2021, DOI:10.32604/jrm.2021.014285

    Abstract This work aimed to help the bamboo industry develop methodology for producing imperfection-free bamboo boards that can serve either decorative or structural benefit to consumers seeking to engage with the bioeconomy. Specifi- cally, softened and slotted bamboo tubes were handled by a roller device with nails to render crack-free flattened bamboo board. Softening temperature and time were optimized herein according to findings regarding chemical composition and board mechanical properties. The optimal softening parameters for saturated steam heat treatment is proved to be 160°C for 8 minutes. The flattened bamboo board possesses an increased bending strength of 101.5 MPa and a… More >

    Leaf and stem anatomy and micromorphology in two cut flower cultivars of Rosa hybrida L.

    Cohen1 G, L Mascarini1, CC Xifreda2

    Phyton-International Journal of Experimental Botany, Vol.81, pp. 199-204, 2012, DOI:10.32604/phyton.2012.81.199

    Abstract Micromorphological and anatomical differences in leaf epidermis and stem xylem of Rosa hybrida ‘Lovely Red ‘ (LR) and ‘Rouge Baiser’ (RB), commercially grown in Buenos Aires, Argentina, were examined in the lower half of the terminal leaflet of 5-foliate leaves and in the basal part of stem, respectively. Digital images obtained from SEM and a phase contrast microscope were used with this purpose. Epicuticular wax, which was present on both sides of the leaves, was more abundant in LR than in RB. Stomata were only present on the abaxial side; they were 111 and 129 per mm² in LR and… More >
