Abstract

One of the sustainable solutions for cementitious materials could be the inclusion of locally available raw materials with possible lower environmental and/or economic impacts that meet technical requirements. This study focuses on waste perlite and recycled concrete powders, which are wastes from natural or artificial rock. Their effects on hardened and fresh properties were investigated by cement replacement of 15, 30 and 45 m%. The waste perlite powders demonstrated higher reactivity, while the recycled concrete powder would act mainly as a filler material. When using recycled concrete and waste perlite powders, an adverse effect was identified on the examined fresh properties.

废珍珠岩和再生混凝土粉作为补充胶凝材料的研究

胶凝材料的可持续解决方案之一可能是包含当地可用的原材料，这些原材料可能对环境和/或经济影响较小，符合技术要求。本研究主要针对天然或人造岩石中的废珍珠岩和再生混凝土粉进行研究。通过水泥置换量分别为15%、30%和45%，研究了它们对硬化和新鲜性能的影响。废珍珠岩粉具有较高的反应活性，而再生混凝土粉主要作为填充材料。当使用再生混凝土和废珍珠岩粉时，对所检查的新鲜性能产生了不利影响。

期刊介绍： Periodica Polytechnica Civil Engineering is a peer reviewed scientific journal published by the Faculty of Civil Engineering of the Budapest University of Technology and Economics. It was founded in 1957. Publication frequency: quarterly. Periodica Polytechnica Civil Engineering publishes both research and application oriented papers, in the area of civil engineering. The main scope of the journal is to publish original research articles in the wide field of civil engineering, including geodesy and surveying, construction materials and engineering geology, photogrammetry and geoinformatics, geotechnics, structural engineering, architectural engineering, structural mechanics, highway and railway engineering, hydraulic and water resources engineering, sanitary and environmental engineering, engineering optimisation and history of civil engineering. The journal is abstracted by several international databases, see the main page.
