    A Comparative Investigation of the Biodegradation Behaviour of Linseed Oil-Based Cross-Linked Composites Filled with Industrial Waste Materials in Two Different Soils

    Eglė Malachovskienė1,*, Danguolė Bridžiuvienė1, Jolita Ostrauskaitė2, Justina Vaičekauskaitė2, Gailė Žalūdienė3

    Journal of Renewable Materials, Vol.11, No.3, pp. 1255-1269, 2023, DOI:10.32604/jrm.2022.023574

    Abstract The biodegradation of polymeric biocomposites formed from epoxidized linseed oil and various types of fillers (pine needles, pine bark, grain mill waste, rapeseed cake) and a control sample without filler was studied during 180 days of exposure to two types of forest soil: deciduous and coniferous. The weight loss, morphological, and structural changes of polymer composites were noticed after 180 days of the soil burial test. The greatest weight loss of all tested samples was observed in coniferous forest soil (41.8%–63.2%), while in deciduous forest soil, it ranged between 37.7% and 42.3%. The most significant changes in the intensities of… More >

    Evaluating Simultaneous Impact of Slag and Tire Rubber Powder on Mechanical Characteristics and Durability of Concrete

    Mostafa Amiri1, Farzad Hatami2,*, Emadaldin Mohammadi Golafshani3

    Journal of Renewable Materials, Vol.10, No.8, pp. 2155-2177, 2022, DOI: 10.32604/jrm.2022.019726

    Abstract In this experimental study, the impact of Portland cement replacement by ground granulated blast furnace slag (GGBFS) and micronized rubber powder (MRP) on the compressive, flexural, tensile strengths, and rapid chloride migration test (RCMT) of concrete were assessed. In this study, samples with different binder content and water to binder ratios, including the MRP with the substitution levels of 0%, 2.5% and 5%, and the GGBFS with the substitution ratios of 0%, 20% and 40% by weight of Portland cement were made. According to the results, in the samples containing slag and rubber powder in the early ages, on average,… More > Graphic Abstract

    A Review on the Utilization of Waste Material for Autoclaved Aerated Concrete Production

    R. A. Rahman1, A. Fazlizan1,*, N. Asim1, A. Thongtha2

    Journal of Renewable Materials, Vol.9, No.1, pp. 61-72, 2021, DOI:10.32604/jrm.2021.013296

    Abstract Autoclaved aerated concrete (AAC) has become more attractive due to its excellent and environmental-friendly properties in building construction. AAC is relatively lightweight, possesses lower thermal conductivity, higher heat resistance, lower shrinkage, and fasten construction than normal concrete. AAC is a combination of silica sand, cement, gypsum, lime, water, and an expansion agent. To improve its physical and mechanical properties and reduce its production cost, tremendous innovations where waste materials were utilized as partial replacement of AAC materials were done. This paper is intended to present the literature on the utilization of waste materials as a means of a partial replacement… More >
