The aim of this study is to examine capability of geopolymer in immobilization and entrapping of heavy metals bearing materials; also, dose optimization that will be more efficiently affect the resultant geopolymer structure will be studied. The main binder used for mortar preparation was water cooled slag in addition to air cooed slag as fine aggregate passing sieve of one mm in equal ratio, whereas the used activator was 8 % wt sodium hydroxide. The studied heavy metals bearing materials were barium sulfate, lead phosphate, lead slag and electric arc furnace dust used as partial replacement of water-cooled slag. Physico-mechanical characterization of each set of samples was conducted using XRD, FT-IR, SEM, compressive strength and bulk density. Results demonstrated that barium sulfate can be efficiently used up to 2%, lead phosphate up to 1%, lead slag up to 5%, and electric arc furnace dust up to 10%.

这项研究的目的是检验地聚合物对重金属轴承材料的固定和截留能力。同样，将研究将更有效地影响所得地质聚合物结构的剂量优化。用于灰浆制备的主要粘合剂是除空气冷却的炉渣以外的水冷炉渣，细粒料通过筛的比例为1mm，而空气冷却的炉渣为等比例，而所用的活化剂为8％wt的氢氧化钠。所研究的重金属轴承材料为硫酸钡，磷酸铅，铅渣和电弧炉粉尘，以部分替代水冷渣。使用XRD，FT-IR，SEM，抗压强度和堆积密度对每组样品进行物理力学表征。结果表明，硫酸钡最多可有效使用2％，磷酸铅最多1％，
