Application of polycarboxylate in low cement castables

Materials Research Innovations, 2015
The performance of low cement castable with polycarboxylate was studied by comparing the effects of polycarboxylate superplasticisers KS-JS70 and LMS-P and sodium tripolyphosphate on castable samples. The fluidity, bulk density, apparent porosity, compressive strength and bending strength of the castable samples at room temperature were determined, and

The rheological properties of polyelectrolyte cements

Journal of Oral Rehabilitation, 1981
SummaryThe rheological behaviour of six setting carboxylate cements was studied by capillary techniques in the shear rate of 0.65–65 s−1 and the cements were found to behave as power law fluids. All cements became dilatant as setting progressed and the kinetics of apparent viscosity increase, were found to follow an exponential function of time, exp ...

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.

The Influence of Various Admixes on the Physical Properties of a Polycarboxylate Cement

Journal of Dental Research, 1983
Aluminum oxide, aluminum hydroxide, aluminum fluoride-trihydrate, and titanium dioxide hydrate were added to a commercial polycarboxylate cement. The first substance increased the setting time and certain physical properties. The others decreased the same properties to varying degrees.

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.
