Interaction between C3A, silica fume and naphthalene sulphonate superplasticiser in high performance concrete
AbstractIn high performance concrete, fillers and superplasticisers are typically added to the binder system. It is clear that cement, filler and admixture interact, and influence concrete properties. By means of an experimental programme on concrete with different types of Portland cement, with and without partial cement replacement by silica fume, and considering a naphthalene sulphonate superplasticiser, the interaction between C3A, silica fume and naphthalene sulphonate superplasticiser has been investigated.A higher C3A content of the Portland cement leads to a higher required dosage of superplasticiser. Partial cement replacement by silica fume leads to an acceleration of the second hydration peak (hydration of C3S). Early age strength development of the concrete is higher in case of a higher C3A content.
