The tests conducted in the LAOP conform with the standards approved by the American Society of Testing Materials (ASTM) which are briefly described in Appendix A of the report.

This report will focus on five admixtures tested on four different Lafarge cements. One of the admixtures was targeted for possible future commercial use. A brief profile of all of the admixtures and the cement used is given within the report. It was concluded that the admixture called 325-N would yield the highest strength over a 28 day period. It was only better by less than 4% in comparison to the compressive strengths of the other admixtures. Further details on each of the individual trial mixes can be found in Appendix B.

It is recommended that when conducting a program similar to this one that the initial set times and the 24 hour compressive strengths be eliminated as their result reflect to no certain extent how the concrete will stand up over a 28 day period.

Although Lafarge uses similar processes to manufacture cements at all of its locations across Ontario, the cement

The batching procedure for each mix in the LAOP went as follows:

While a cement manufacturer might design a cement to work dynamically with various aggregates, it has never been a task for the cement manufacturer to make a cement to work better with an admixture. It is the task of the admixture manufacturer to refine an admixture until it works properly with the cement or at least until the desired effect on the concrete has been accomplished. This comes as no surprise as admixtures were invented to improve upon the cements abilities to create a better concrete.
