摘要/Abstract

摘要： 为提高废旧陶瓷的再生利用率,将陶瓷颗粒与陶瓷粉作为再生混凝土骨料与掺合料进行再生利用.运用正交设计的试验方法,以陶瓷粉、陶瓷颗粒、再生细骨料、粉煤灰、硅灰为5因素,每个因素设置4个水平,共设计16组配合比方案,进行抗压、导热等试验,得到陶瓷再生混凝土的强度、导热系数等物理力学参数,并寻找出最优配合比.试验结果表明最佳配合比为:陶瓷粉的质量分数为10%,陶瓷颗粒的质量分数为20%,再生细骨料的质量分数为40%,粉煤灰的质量分数为15%,硅灰的质量分数为5%.

Abstract: In order to improve the recycling efficiency of ceramics, ceramic particles and ceramic powder were reused as aggregates and admixtures for ceramic-recycled concrete. By using test method of the orthogonal design and taking ceramic powder, ceramic particles, recycled fine aggregate, fly ash and silica fume as five factors, and setting further four levels for each factor, sixteen groups of mix proportion schemes are designed in this paper. Tests of compression and thermal conductivity are carried out respectively. The physical and mechanical parameters such as strength and thermal conductivity of the ceramic-recycled concrete are obtained therefore, and the optimal mix ratio is found as a result. The test results show that the best mix ratio is as follows: the mass fraction of ceramic powder is 10%, the mass fraction of ceramic particles is 20%, the mass fraction of recycled fine aggregate is 40%, the mass fraction of fly ash is 15%, and the mass fraction of silica fume is 5%.
