| Abstract: | This paper aims to clarify the influence of the clinker SO3 on the cement characteristics. The impact on the strength development rate and the level of sulfate resistance were studied .The results show that increasing the amount of clinker SO3 at low alkali level reduces the percentages of the tricalcium aluminate (C3A) and alite as well as the alite/belite ratio, leading to a modification in the cement quality.For these reasons cements produced from a clinker containing high sulfate and low alkali, have slower strength development and higher sulfate resisting level than that produced with low sulfate clinker. |
