Cement Wikipedia
The presence of heavy metals in the clinker arises both from the natural raw materials and from the use of recycled byproducts or alternative fuels The high pH prevailing in the cement porewater 125 pH 135 limits the mobility of many heavy metals by decreasing their solubility and increasing their sorption onto the cement mineral phases
