Admixtures are prefect for your concrete, mortar and plaster mixes. Sometimes they are a necessity, whereas in other cases they serve to enhance the mix and make it easier for you by saving time, energy and money.

In general, they are used either before the mix is laid, added in the mix, or used after the mix has been laid (think Prep / Add / Finish).

With admixtures, choosing the right product can be critical to ensure you get the best result so if in doubt, contact the team at Cemix for expert advice.
