The purpose of this study is to investigate certain features of a novel material proposed to serve as an impervious liner in landfills. Various ratios of bentonites and zeolites (B/Z) compacted at optimum water content were tested to determine the strength parameters, permeability, pH, heavy metals and other properties. A B/Z ratio of 0.10 was found to be an ideal landfill liner material regarding its low hydraulic conductivity and high cation exchange capacity. The use of B/Z mixtures as an alternative to clay liners would provide potential to significantly reduce the thickness of base liner for landfills.
本研究的目的是调查一种新型材料的某些特性，该材料被提议用作垃圾填埋场的防渗衬垫。对在最佳含水量下压实的各种膨润土与沸石比例（B/Z）进行了测试，以确定强度参数、渗透性、pH值、重金属及其他特性。发现B/Z比例为0.10时，因其低水力传导率和高阳离子交换容量，是一种理想的垃圾填埋场衬垫材料。使用B/Z混合物替代粘土衬垫，将有可能显著减小垃圾填埋场底部衬垫的厚度。
