Refractory Cement - Composition, Installation, Use - Civil

In Refractory cement, a bulk refractory grain mass is initially bonded with a fired bond, which is fired with reaction component Si 3 N 4 and/or Si 2 ON 2 which protects the ultimate high temperature sintered cement from the effect of erosion at the time of using the cement as a liner for furnace walls, troughs.

Effect of Modifying Additives on Mechanical Properties of

Retarding Admixtures. Retarding admixtures slow down the hydration of cement, lengthening set time. Retarders are beneficially used in hot weather conditions in order to overcome accelerating effects of higher temperatures and large masses of concrete on concrete setting time. Accelerating admixtures. Accelerators shorten the set time of concrete, allowing a cold-weather pour, early removal of forms, early surface finishing, and in some cases, early load application. Superplasticizers. Superplasticizers, also known as plasticizers, include water-reducing admixtures. Compared to what is commonly referred to as a "water reducer" or "mid-range water reducer", super plasticizers are "high-range water reducers". Water reducing admixtures. Water reducing admixtures require less water to make a concrete of equal slump, or increase the slump of concrete at the same water content. People also ask Which is the most common refractory cement additive? One major class of refractory cement additives is that of chrome compounds; chrome flour, chrome sand (chromite) and directly chromium (iii) oxide (chromia, Cr 2 O 3 ). It is stated that 18% of all chromite is used for refractory purposes (9). Refractory Cements, Refractory Materials
