Dataset of "UTILIZATION OF PLASMA-PYROLYZED WIND-TURBINE BLADES IN MAGNESIUM OXYCHLORIDE COMPOSITES FOR ECO-FRIENDLY CONSTRUCTIONS"

The pursue of greenhouse gasses (GHG) emissions reduction cannot overlook construction industry, which is one of the main global contributors. Significant part of the environmental burden is connected to Portland cement (PC) not only in terms of emissions, but also raw material demand. One of the promising alternatives are magnesium oxy-chloride (MOC) cements known for their supreme bonding properties, and, compared to ordinary PC, enhanced mechanical properties and significantly reduced GHG emissions. However, poor water stability is hindering its adoption as mass PC replacement. This article focuses on a composite with MOC matrix and waste glass slag filler. It has been reported that glass has beneficial effect on mechanical properties and water stability. Additional environmental advantage lies in the slag origin – end-of-life wind-turbine blades, which is a troublesome and hard to recycle waste. The slag was produced as a byproduct of plasma pyrolysis, where the main product is syngas, which can serve as an energy source. Nevertheless, glass slag is still a pestilent waste as leaching can occur and glass dust can cause lung damage, therefore immobilization is preferable. Reference samples containing silica sand (SS) were prepared along with samples with 50%, 100%, and 150% substitution of SS by PPWB. PPWB slag was analysed in terms of composition (XRF, XRD, EDS), microstructure (OM, SEM), particle size distribution (LD) and physical properties. MOC composite samples were examined in terms of composition (XRF, XRD, EDS), microstructure (OM, SEM, MIP) and physical, mechanical, and water stability properties. Despite nonnegligible differences in microstructure of all samples the compressive strength and softening coefficient remained without significant difference across all composite samples. Nevertheless, flexural strength and Young's modulus increased when slag filler was present. The dependence of properties on fillers content was not implicit, which underlines the complex nature of heterogenous materials. While water stability wasn't improved sufficiently, the results are still satisfactory as pestilent original waste was utilized with high efficiency and the price of MOC composite was lowered by slag's negative price, while some properties were enhanced and rest did not deteriorate.
