Effect of the clinker composition on the threshold

2012-8-1  The purpose of this work was to study the effect of the clinker composition on the threshold limits for Cu, Sn or Zn. For each trace element, the effect of two parameters on the threshold limit was tested. The first parameter was the Bogue C 3 S content while the second was the Bogue interstitial phase content. The concentration range chosen is still representative of the average mineralogical composition of a Portland cement clinker.

Effect of clinker free lime and cement fineness on the

2020-6-26  Studies conducted on the effect of clinker free lime on the cement properties were very low and for the purpose of producing quality material, we studied the effect of the clinker free lime on the cement physicochemical properties, like: the expansion, the setting time and the compressive strength. For this, two types of clinker were used to produce cements study. The first type has a clinker free lime content is less of 2% and the second type has a high content of free lime (unburnt). The corresponding cements of the two clinker types were prepared with an identical proportion of additions to eliminate their effects on the cement physicochemical properties. The results have shown that the clinker free lime has a great effect
