摘要
废弃陶瓷作为一种固体废弃物,质地坚硬,主要化学组成为SiO2 和Al2O3.这些特点使废弃陶瓷经简单的物理处理后具有部分替代天然砂石骨料和作为掺合料的潜力.将废弃陶瓷应用于水泥基复合材料的生产中,可缓解天然砂石过度开采、水泥生产过程的高能耗与污染及废弃陶瓷堆积所造成环境污染等问题.本文首先分析了各类废弃陶瓷的物理化学性质;而后从废弃陶瓷在水泥基复合材料中的不同应用形式方面入手,综合评述了废弃陶瓷粗、细骨料及废弃陶瓷粉对水泥基复合材料基本力学性能影响,揭示了废弃陶瓷对水泥基复合材料力学性能的影响机制;最后,讨论并给出了废弃陶瓷在水泥基复合材料中,尤其在绿色超高性能混凝土和高力学保持性能的耐高温混凝土,进一步应用和研究的建议.
Abstract
As one of the solid wastes,ceramic wastes have a hard texture,and their main chemical composition are SiO2 and Al2O3.These characteristics make properly treated ceramic wastes have the potential to replace natural sand,gravel aggregates and act as admixtures.Application of ceramic wastes into cementitious composites will contribute to alleviate the problems of environmental pollution caused by the overexploitation of natural sand and gravel,high energy consumption and pollution in cement production,and the accumulation of ceramic wastes.This paper first briefly describes the physical and chemical properties of various types of ceramic wastes.Then,from the different application forms of ceramic wastes in cementitious composites,this paper comprehensively reviews the research status of the effect of ceramic waste aggregates and ceramic waste powders on the basic mechanical properties of cementitious composites,reveals the influencing mechanisms of ceramic wastes on the basic mechanical properties of cementitious composites.Finally,suggestions for further application and research of cementitious composites with ceramic wastes,especially in green and ultra-high-performance concrete and mechanical property retention after high temperature refractory concrete,are put forward based on the problems existing in the current research.
