A novel cellulose based stabilizing admixture for self compacting concrete

Research output: Contribution to journalArticleScientificpeer-review

Abstract

A Novel Cellulose Based stabilizing Admixture (NCBA) with unique rheological properties was introduced. Rheological effects of NCBA were studied in cement paste, mortar and self compacting concrete. It was observed that NCBA increased only the mixes yield stress, whereas commercial melamine sulphonate based stabilizer increased mixes’ yield stress and plastic viscosity. This phenomenon made it possible to produce a good quality self compacting concrete with relatively low performance aggregates and a high water /cement –ratio.
