Cement-superplasticizer interactions at ambient temperatures
Influence of superplasticizers on rheology, phase composition, pore water and heat of hydration of cementitious systems. The rheological behaviour of three superplasticizers (polymelamine sulfonate, polynaphthalene sulfonate, polyacrylate) in combination with various Swiss cements (CEM I 42,5) was studied.

Environmental exposure assessment of sulfonated naphthalene formaldehyde condensates and sulfonated naphthalenes applied as concrete superplasticizers
The environmental impact of sulfonated naphthalene formaldehyde condensates (SNFC) deriving from constructon activities is studied. Therefore an analytical method for the determination of SNFC in water was developed. Field studies were conducted on two tunnel construction sites. [125 pages, 6,6 MB, PDF]

The Rheology of Cementitious Materials
Working mechanism of superplasticizers which induce steric repulsion between cement particles (polycarboxylates) and their role in concrete rheology.
