Figure 2-1. Worksheet for concrete trial mix data.
Use all the measured quantities of cement, water, and air-entrained admixture.
NOTE: It is not normal practice to buy air-entrained cement (Type IA) and then add an air-entrained admixture;
however, if the only cement available was Type IA and it did not give the needed air content, addition of an air-
entraining admixture would be necessary to achieve frost resistance.
