CFRC based on alumina hydraulic binders are similar with respect to hardening mechanism to low-cement refractory concretes (LCRC) and ultralow cement concretes (ULCRC). They are characterized by significant strengthening in the heat treatment temperature range 200 – 300°C and severe weakening in the range 600 – 1000°C. By introducing silica sols or microsilica into their composition it is possible not only to reduce or eliminate the weakening effect, but also to increase their strength after firing due to mullite formation. CFRC based on alumina binders have improved thermomechanical properties compared with LCRC. Comparative evaluation of CFRC based on hydraulic binders with other types of refractory concretes is provided.

基于氧化铝水硬性粘结剂的CFRC在低水泥耐火混凝土（LCRC）和超低水泥混凝土（ULCRC）的硬化机理方面相似。它们的特点是在200 – 300°C的热处理温度范围内显着增强，而在600 – 1000°C的温度范围内则明显减弱。通过将硅溶胶或微硅石引入它们的组成中，不仅可以减少或消除弱化作用，而且还可以由于烧成而形成莫来石而增加其强度。与LCRC相比，基于氧化铝粘合剂的CFRC具有改进的热机械性能。提供了基于水硬性粘结剂的CFRC与其他类型的耐火混凝土的对比评估。
