Summary

The world civil construction generates large environmental liabilities that affect the entire modern society. Vary researches have been carried out aiming at the use of different types of solid waste in the development of eco-friendly building materials, promoting the circular economy process. This special edition aims to discuss and present innovative manuscripts on the theme of sustainable materials, aiming at the reuse of waste in materials such as mortar, ceramics, concrete, activated alkali, geopolymers and others, which fill gaps in international scientific literature.

    Workability and Strength of Ceramsite Self-Compacting Concrete with Steel Slag Sand

    Suiwei Pan, Anqi Ren, Yongli Peng, Min Wu, Wanguo Dong, Chunlin Liu, Depeng Chen
    Journal of Renewable Materials, Vol.11, No.2, pp. 881-904, 2023, DOI:10.32604/jrm.2022.023000

    Abstract This study focuses on the workability and compressive strength of ceramsite self-compacting concrete with fine aggregate partially substituted by steel slag sand (CSLSCC) to prevent the pollution of steel slag in the environment. The SF, J-ring, visual stability index, and sieve analysis tests are primarily employed in this research to investigate the workability of freshly mixed self-compacting concrete containing steel slag at various steel slag sand replacement rates. The experiment results indicate that CSLSCC with the 20% volume percentage of steel slag (VPS) performs better workability, higher strength, and higher specific strength. The 7-day compressive strength of CSLSCC with the… More >

    Study on the Hydration and Physical Properties of Cement by M18 Polycarboxylate Superplasticizer Modified Graphene Oxide

    Dalong Liao, Dongxu Li, Shun Zhou, Xiaotao Zhang, Ying Fang
    Journal of Renewable Materials, Vol.11, No.2, pp. 625-641, 2023, DOI:10.32604/jrm.2022.022501

    Abstract Graphene oxide (GO) as a new nano-enhancer in cement-based materials has gained wide attention. However, GO is easy to aggregate in alkaline cement mortar with poor dispersibility. This hinders its application in practical infrastructure construction. In this work, GO-M18 polycarboxylate compound superplasticizer (GM) were obtained by compounding the M18 polycarboxylate superplasticizer with GO solution at different mass ratios. The dispersion of GM in alkaline solution was systematically studied. The phases and functional groups of GM were characterized by XRD and FTIR. The effects of GM on the cement mortar hydration and the formation of microstructure were investigated by measuring the… More >

    The Effect of Basalt Fiber on Concrete Performance under a Sulfate Attack Environment

    Qiang Su, Jinming Xu
    Journal of Renewable Materials, Vol.11, No.1, pp. 233-244, 2023, DOI:10.32604/jrm.2023.020573
    (This article belongs to this Special Issue: Circular Economy in the Development of Eco-Friendly Materials for Construction)
    Abstract To enhance the sulfate attack resistance performance of concrete, Sulfate erosion test was carried out on basalt fiber concrete with different contents, selecting a concentration of 5% sulfate solution and using a dry−wet cycle mechanism attack of basalt fiber-reinforced concrete (BFRC). Every 15 dry−wet cycles, the mass, compressive strength, splitting tensile strength, and relative dynamic elastic modulus of BFRC were tested, and the SO42− concentration was measured. This work demonstrates that the mass, relative dynamic elastic modulus, compressive and splitting tensile strength of BFRC reveal a trend of climb up and then decline with the process of the dry−wet cycle.… More >

    Research and Application Status and Development Trend of Alkali-Activated Binder Powder for Mine Backfill

    Qian Zhou, Yueyue Zhang, Juanhong Liu, Aixiang Wu, Hongjiang Wang
    Journal of Renewable Materials, Vol.10, No.12, pp. 3185-3199, 2022, DOI:10.32604/jrm.2022.020316
    (This article belongs to this Special Issue: Circular Economy in the Development of Eco-Friendly Materials for Construction)
    Abstract To improve the economic and social benefits of mining and backfill, it is necessary to find the backfill materials suitable for mineral mining, improve the various properties of the filling materials, and develop low cost, high performance new filling materials. Portland cement is neither environmentally friendly nor economical. Currently, we have begun to study and apply some industrial waste, such as slag, fly ash, and other solid wastes, with certain activities as the primary component of cementing material that will not only meet the technical requirements of filling, but also comprehensively utilize industrial waste and possess a benign, sustainable lifecycle… More >

    A Modeling Method for Predicting the Strength of Cemented Paste Backfill Based on a Combination of Aggregate Gradation Optimization and LSTM

    Bo Zhang, Keqing Li, Siqi Zhang, Yafei Hu, Bin Han
    Journal of Renewable Materials, Vol.10, No.12, pp. 3539-3558, 2022, DOI:10.32604/jrm.2022.021845

    Abstract Cemented paste backfill (CPB) is a sustainable mining technology that is widely used in mines and helps to improve the mine environment. To investigate the relationship between aggregate grading and different affecting factors and the uniaxial compressive strength (UCS) of the cemented paste backfill (CPB), Talbol gradation theory and neural networks is used to evaluate aggregate gradation to determine the optimum aggregate ratio. The mixed aggregate ratio with the least amount of cement (waste stone content river sand content = 7:3) is obtained by using Talbol grading theory and pile compactness function and combined with experiments. In addition, the response… More >
