So my dosage has been 3 oz per 60lb bag and the concrete flows sooooo much better Im sure regular dosage would make concrete move like gooey melted plastic Like other reviewers have said it allows you to use less water while still being workable more so actually resulting in stronger concrete.
Oct 01 2018018332Twenty batches of grout samples were designed by varying the watercement ratios from 0 5 to 2 and clay dosages from 5 to 45 which are in the ranges commonly used in engineering practice The results showed that the optimal performance of the clay cement grout was highly dependent on the clay dosage and watercement ratio.
