The compatibility of polycarboxylate-type superplasticizers with cement

Journal of Wuhan University of Technology-Mater. Sci. Ed., 2005
Four polycarboxylate-type (PC) superplasticizers of different functional groups were used; their dispersing and retaining behaviors were analyzed through ZETA potential measurement, mini-slump test of cement paste and performance test of concrete. The experimental results show that the dispersing and flow-retaining ability of PC was determined by two ...

Polycarboxylate Polymers and Blends in Different Cements

Cement, Concrete, and Aggregates, 2004
Abstract During the last few years, polycarboxylate based polymers have become very popular. They contain a polycarboxylic backbone onto which ethyleneoxide side chains have been grafted. However its dispersing and slump keeping properties vary significantly, depending on the chemical structure.

Physical Properties of Some Zinc Phosphate and Polycarboxylate Cements

Acta Odontologica Scandinavica, 1983
Several physical properties were measured for two zinc phosphate and three polycarboxylate cements. The specimens were tested in compression 24 h after they had been made. Two series of specimens were examined. In one series the cement powders were given a correct treatment, protected from atmospheric humidity.

Compatibility of polycarboxylate superplasticizers with cements

2006
Superplasticizers are nowadays often used for ready-mix concrete, but also for other purposes in concrete technology. In most cases, without adding a superplasticizer to concrete, it is not possible to achieve the desired properties of fresh and hardened concrete. Properties of fresh concrete, such as slump, slump loss with time, segregation, bleeding,

[Properties of the polycarboxylate and glass-ionomer cements].

Hellenika stomatologika chronika. Hellenic stomatological annals, 1991
This paper is a review article on the properties of the polycarboxylate and glass-ionomer cements. Much research has been done during the past years on the strength, solubility and adhesion of these cements with the dental tissues and the conclusions on these topics are discussed in this paper.
