ARMORSIL RETARDER 200
PCE BASED WATER REDUCING AND RETARDING, PLASTICIZING ADMIXTURE
ARMORSIL Retarder 200 is a polycarboxylate based superplasticizer developed particularly for use in ready mixed concrete to give extended slump retention and high strength development of high speciﬁcation grade concrete mixes. ARMORSIL Retarder does not contain calcium chloride and other corroding materials. ARMORSIL Retarder is a blend of polymer-based plasticizer and proprietary retarding agent.
The chemical process of ARMORSIL Retarder when activated temporarily stops the hydration process, delaying the initial setting time in proportion to the amount of dosing. At the completion of the initial setting time, curing commences at a regulated rate. Concrete with ARMORSIL Retarder 200 can maintain workability in excess of 3 hours.
