The American Concrete Institute (ACI) is giving you all of the information to know about chemical admixtures for concrete in their new guide about the admixtures which are used on a daily basis cast-in-place- and precast concrete industries. The report divides admixtures into 12 groups including air entraining and set-retarding.
Successful use of these chemical admixtures requires compatibility, setting times, and early strengths that are appropriate to the placing environment. This and more are addressed in this new report from ACI:
Each category of admixture addresses common use and the potential benefits of a properly proportioned concrete mixture to various professionals, including the concrete contractor, concrete producer, and design professional. The sustainability of chemical admixtures and their role in sustainable construction is addressed. Finely divided mineral admixtures, such as fly ash or raw and processed natural pozzolans, are addressed in ACI 232.2R and ACI 232.1R, respectively.
