高浓度除冰剂,甚至在没有冰冻作用情况下,所带来的碱土金属氯化物也会对混凝土产生持续性损伤。位于德国杜塞尔多夫市的水泥工业研究院,针对各种类型除冰剂对混凝土路面砖的影响进行了研究。实验室试验结果表明:具有足够的水泥含量和低水灰比的混凝土路面砖,显示出很好的抗冻性能和抗除冰剂侵蚀的能力。高浓度碱土金属氯化物溶液对混凝土路面砖没有产生明显的损坏。 High concentrations of de-icing agent, even in the absence of the role of ice, the resulting alkaline earth metal chloride will cause continuous damage to the concrete. The Cement Industry Research Institute in Düsseldorf, Germany, studied the impact of various types of de-icing agents on concrete pavers. Laboratory tests show that concrete pavers with adequate cement content and low water-cement ratio exhibit good frost resistance and resistance to de-icing agents. High concentration of alkaline earth chloride solution on the concrete pavement did not produce significant damage.
