Effects of Processed Agro-Residues on the Performance of Sodium Chloride Brine Anti-Icer

Abstract

In this laboratory study, the performance and impacts of several new types of anti-icer were examined. A chemico-biological process was employed to prepare liquid extracts from two agro-based feedstocks, specifically, dandelion leaf and sugar beet leaf. The following parameters were examined as a function of the formulation design: ice-melting capacity at -3.9 °C (25 °F), mass loss, and compressive strength of Portland cement mortar (PCM) samples after 10 rapid freeze-thaw cycles with anti-icer exposure, the corrosivity of C1010 carbon steel after 24-h immersion in anti-icer solutions, and the anti-icer impact on asphalt binder. One viable formula ("the best performer") was tested for the freezing point depression phase diagram and friction coefficient of asphalt pavement treated by anti-icing formulation. The agro-based extracts improved the properties of the "green" anti-icer mixtures and the friction coefficient of anti-iced pavement. In addition, they were environmentally friendly in terms of low COD and BOD values. The developed anti-icers contain less additive chemicals than traditional agro-based anti-icers, which likely helps to reduce their impacts on the environment.
