Admixtures are used to give special properties to fresh or hardened concrete Admixtures may enhance the workability of fresh concrete and the durability strength of hardened concrete Admixtures are used to overcome difficult construction situations such as hot or cold weather placements pumping requirements early age strength requirements
Chemical Admixtures for Concrete ACCELERATORS Özge Andiç Çakır PhD Accelerators Definition •An accelerating admixture is a material that is added to concrete for reducing the time of setting and accelerating early strength development Accelerators Classification •Accelerating admixtures •Water reducing and accelerating admixtures Usage •Accelerating admixtures are used in
Concrete admixtures may exhibit substantially different performances with different brands or changing chemistry of cement This is usually most noticeable in the retarding effect at a specified dosage In those cases where a pre approved admixture does not seem to provide satisfactory performance please immediately notify the Materials Pavements Section of the Construction Division at 512

Admixtures are substances added to concrete mixes in order to modify one or more properties of the mixes to render them suitable for specific needs or requirements For example if a concrete mix is to be rendered suitable for easy pouring and compacting in a structure congested with reinforcement an admixture that enhances workability is a much better option than adding further water to the
