Magnesia-Based Cement Composites with Recycled Waste Tire Rubber Filler

Popis výsledku v původním jazyce

Annually, 1.5 billion waste tires are produced world-wide. With limited capacity of landfills and law restrictions researchers are looking for other ways to utilize this waste. Among these approaches, use of grinded tires as part of building materials is becoming popular sustainable solution. Therefore, the aim of the presented research is to design and investigate material characteristics of magnesia-based composites with incorporated grinded waste tire-based filler. Tire rubber was applied in the form of 100 %, 125 % and 150 % dosage of filler. Chemical composition of magnesia binder was investigated using X-ray fluorescence technique (XRF). For the developed composites, workability, structural, mechanical, and thermal properties were studied. Workability of fresh composite mixtures was characterized by flow table test. Among basic structural characteristic of hardened composites, bulk density, specific density, and total open porosity were investigated. Analysis of mechanical resistance included flexural strength, compressive strength, and dynamic modulus of elasticity tests. Thermal properties were measured by a transient plane source (TPS) technique. The replacement of silica filler and raise of filler content led to the reduced bulk and specific densities which was accompanied with great improvement of thermal insulation capability of lightened magnesium oxychloride cement (MOC)-based composites. On the other hand, the incorporation of grinded tire rubber negatively affected the mechanical resistance of produced composites. Based on the experimental investigation and conducted analyzes, the developed MOC-based composites with tire rubber filler have potential to utilize waste tires dumped on landfills with preserving primarily used natural sand. Moreover, MOC-based composites can be considered as environmentally friendly materials with lower carbon footprint and promising alternatives to Portland cement composites.
