The invention relates to the use of methyldiethanolamine as a grinding aid for cement, and in particular its use as a strength enhancing grinding aid for cement. The compressive strength may be enhanced by the methyldiethanolamine at both at an early stage (1and/or 3 days from the start of hydration) and at a late stage (7 and/or 28 days from the start of hydration). The early stage strength enhancing effect is particularly notable for a blended cement composition, with lower clinker content.
