摘要

两种硅酸盐水泥浆体，CEM I 42.5R和CEM III/A 52.5N，在一年的水化期内暴露于软水浸出。通过测定微量元素在一段时间内的孔溶液浓度来研究微量元素的迁移率。本研究包括11种微量元素：锑、砷、镉、铬、钴、铜、汞、镍、铅、钒和锌。研究了孔隙溶液微量元素浓度在监测有害浸出反应和预测环境风险中的可能用途。

Mobility of Trace Elements in Pore Solutions of Portland Cement Pastes Exposed to Leaching

Two Portland cement pastes, CEM I 42.5R and CEM III/A 52.5N were exposed to leaching by soft water throughout a one–year hydration period. Mobility of trace elements was investigated by determination of their pore solution concentration in the course of time. Eleven trace elements were included in this research: antimony, arsenic, cadmium, chromium, cobalt, copper, mercury, nickel, lead, vanadium and zinc. The possible usage of the pore solution trace elements concentration in monitoring of deleterious leaching reactions and prediction of environmental risk was investigated.
