In the present article the efficacy of polycarboxylate ethers on the flow of calcium aluminate cement paste and mortar as well as of a low-cement castable is presented. Furthermore, the influence of reactive alumina on flow- and hardening properties of the castable is discussed.
Article
For a successful installation of castables an appropriate flow behaviour is required. In order to acquire a more fundamental knowledge of the flow characteristics of microsilica containing refractories, the complex binder matrix (cement, alumina and microsilica) is studied in the presence of new polycarboxylatebased superplastizisers. Special focus...

... At present, superplasticizers based on naphthalene are widely used. Such as S-3 [3], and in particular on the basis of polycarboxylate esters (РСЕ) [7,[10][11][12][13][14][15]. The most studied is the use of S-3. ...

... There are four types of aluminosilicate castables: the conventional castables (CC) (10-25 wt.% HAC); lowcement castables (LCC) (5-8 wt.% HAC); ultra-low cement castables (ULCC) (1-4 wt.% HAC) and No-cement castables (NCC) (0 wt.% HAC). ULCC and NCC castables have been addressed by several authors [8,[10][11][12][13][14][15][16]. Compared to rigid-shaped bricks, the castables are more economical and easier to use. ...
