22.02.· These three finer ERMAs showed an average decrease in CH content of 24% for 28 days and 37% for 91 days compared to REF cement paste. The average reductions achieved using the coarser ERMAs were 9% for 28 days and 19% for 91 days.

Cement clinker is a solid material produced in the manufacture of Portland cement as an intermediary product. Clinker occurs as lumps or nodules, usually 3 millimetres (0.12 in) to 25 millimetres (0.98 in) in diameter.
