内容简介

The different types of dispersants for refractory applications are discussed briefly. Among the organic dispersants, the focus is put on the polycarboxylate ethers (PCE) as the most recent developed dispersants. Different types of PCEs are presented and discussed with regard to their chemical structure, the mode of action and the influence of these additives on cement hydration. The effects and benefits achieved with these new classes of dispersants in low cement self-flow castables regarding flow properties and strength development are presented. It will be shown that they improve the fresh as well as the hardened properties of the concrete, which is essential in the production of enhanced refractory materials.
