Abstract

Nowadays, polymer-based materials are extensively used for domestic applications because of their ease in economic production and comparable strength. However, most of the polymer materials are non-biodegradable materials. Hence, conservational environmental policies mandate the replacement or recycling of polymer-based domestic products and components. Besides, discarding flyash in the dumpsites produced from coal-fired thermal power plants aggravates environmental pollution (including groundwater resources). Hence, devising effective waste-management strategies or developing technologies for recycling wastes (polymers and flyash) is the need of the hour. This research focuses on the development of sintering technology to fabricate pavement blocks using polymer wastes and flyash. The coupon-level specimens were fabricated by varying the sintering process parameters, and the following properties were evaluated: macrostructure, hardness, density, wear rate, friction coefficient, and water absorption. The influence of sintering process parameters (temperature and time) on the properties of the developed specimen was analyzed using hybrid polynomial – radial basis function models.

利用粉末冶金技术研制券级粉煤灰-聚合物基摊铺机砌块

目前，聚合物基材料因其易于生产和强度相当而在国内得到广泛应用。然而，大多数高分子材料是不可生物降解的材料。因此，环保政策要求更换或回收以聚合物为基础的国内产品和部件。此外，在燃煤火力发电厂产生的垃圾场中丢弃粉煤灰加剧了环境污染(包括地下水资源)。因此，制定有效的废物管理战略或开发回收废物(聚合物和粉煤灰)的技术是当务之急。研究了利用高分子废弃物和粉煤灰烧结制备路面砌块的技术。通过改变烧结工艺参数，制备了复合材料的宏观组织、硬度、密度、磨损率、摩擦系数和吸水性等性能。采用复合多项式-径向基函数模型分析了烧结工艺参数(温度和时间)对试样性能的影响。

期刊介绍： Waste and Resource Management publishes original research and practice papers on all civil engineering and construction related aspects of the resource management cycle, from the minimization of waste, through the re-use and recycling, to the management and disposal of residual wastes. Associated legislation, standards, socio-economic considerations and links with sustainable consumption and production are included. The range of subjects covered encompasses, but is not restricted to, strategies for reducing construction waste through better design, improved recovery and re-use, more efficient resource management, the performance of materials recovered from wastes, and, the procurement, planning, design, construction, operation and logistics of waste and resource management facilities.
