    01.01.2016· Replacement rates of 10–16% of Portland cement are used in order to compensate for drying shrinkage in a concrete repair (Bissonnette et al., 2014). This dilution of the expansive agent in Portland cement avoids dosage errors for the very small quantities of expansive agents that have to be used.

  • Additives and methods for reducing Cement Lime

    This method consists in the use of selected antimony(III) compounds directly added to cement before, during or after grinding. The efficacy of the method relies on the fact that the antimony(III) is a strong reducing agent in alkaline solution and can effectively reduce chromium(VI) to less toxic and less soluble chromium(III). The antimony(III) compounds are in liquid form or in form of
