Yes, Radmyx is compatible with most admixtures.  However, like all crystalline products, Radmyx Concentrate can have a plasticising effect and may cause an extension of set times. The amount of extended set will be affected by mix design, climatic conditions etc. 

Whilst Radmyx Concentrate can be used in conjunction with most admixtures, consideration should be given to the reduction or removal of admixtures that retard such as plasticisers, water reducing admixtures etc.

Whilst generally there is no adverse effect on Radmyx from common admixtures used in concrete, as there are thousands of such products around the world, a trial mix is recommended when using Radmyx Concentrate in addition to other admixtures.
