Superplasticizers and retarders are essential in the production of many cementitious materials.While superplasticizers enhance the cement paste flowability,
The sorption behavior of two lignosulfonates onto two different cements was investigated via GPC and ultraviolet spectroscopy.Rapid sorption occurred and mo
Comb-like copolymers as polycarboxylate ether (PCE) are added to concrete to make it more fluid and facilitate its placement.The evolution of the workabilit
Cement slurries have been designed to remain liquid for extended periods of time (>weeks) until exposed to neutron or ionizing radiation to provide a trigge
This study attempts to estimate the relation between the adsorption of the molecules on calcium silicate hydrates (C-S-H) and their ions complexation on the
