.... extent how the concrete will stand up over a 28 day period. Abstract Although Lafarge uses similar processes to manufacture cements at all of its locations across Ontario, the cements at these different locations may perform differently when they chemically react with an admixture due to the nature of the semetitious material at that plant. When testing an admixture across many different cements it becomes more evident that admixtures do not react the same with cements from different location even if they are of the same type. By this it is meant that some cements may result in higher compressive strengths, while other cements may yield very ....
