Specification of Cement Admixture Fosroc Structuro 335
DESKRIPSI
Cement Admixture Fosroc Structuro 335 is differentiated from conventional superplasticisers in that is based on unique carboxylic ether polymer withlong lateral chains. This greatly improves cement dispersion. At the start of mixing process an electrocstatic dispersion occurs but the presence of the lakteral chains, linked to the polymer backbone, generate a steric hindrance which stabilizes the cement particle’s capacity to separate and disperse. This mechanism considerably reduces the water demand in flowable concrete.
Structuro 335 combines the properties of water reduction and workability retention. It allows the production of high performance concrete and / or concrete with high workability.
Structuro 335 is a particularly strong superplasticizer allowing production of consistent concrete properties aarounf the required dosage.
PENGGUNAAN
