The general nature of the dependence of engineering and service characteristics of refractory concretes with an average cement content, and also low-cement (LCRC), ultra-low cement (ULCRC) and cement-free (CFRC), on the content of CaO (or HAC) in them is analyzed. Significant advantages of cement-free concretes are the reduced moisture content of the concrete mixture, which determines their increased density, a continuous increase in strength (absence of a softening temperature range typical for LCRC and ULCRC), and improved thermomechanical and operational characteristics. With use of CFRC, the insurmountable complexity of the LCRC and ULCRC connected with their initial heating in the dehydration temperature range of the HAC (up to 450°C) is resolved. The main provisions and stages of creating HCBS or artificial ceramic binders as a matrix system of ceramic concrete, i.e., LCRC with improved characteristics, are described. Classification of HCBS groups proposed by the author based on the chemical nature of their solid phase is considered.

无水泥耐火混凝土。第1部分。一般信息。六溴环十二烷和陶瓷混凝土

水泥平均含量以及低水泥（LCRC），超低水泥（ULCRC）和无水泥（CFRC）的耐火混凝土的工程和服务特性对CaO含量的依赖性的一般性质（或HAC）中的内容进行分析。不含水泥的混凝土的显着优点是降低了混凝土混合物的水分含量，这决定了它们的密度增加，强度不断提高（没有LCRC和ULCRC典型的软化温度范围）以及改进的热机械和操作特性。通过使用CFRC，解决了LCRC和ULCRC在HAC脱水温度范围（最高450°C）中的初始加热所带来的难以克服的复杂性。描述了创建HCBS或人造陶瓷粘合剂作为陶瓷混凝土基质体系（即具有改进特性的LCRC）的主要规定和阶段。考虑了作者根据其固相的化学性质提出的HCBS基团的分类。
