摘要

本文介绍了低水泥耐火混凝土（LCRC）的研发成果，这种混凝土的骨料由高岭土制成，最高使用温度为 1500°C。为了获得较高的工作性，应使用需水量较少的窄粒骨料。我们对超塑化剂添加剂的效果进行了比较分析，并评估了它们对以高岭土为原料的 LCRC 性能的影响。结果表明，使用高岭土可为耐火混凝土提供高强度（干燥并首次加热至工作温度后为 50 兆帕）。

Low-Cement Refractory Concrete Based on Kaolin Chamotte Aggregate with Improved Workability

This paper presents the results of the development of low-cement refractory concrete (LCRC) based on an aggregate made of kaolin chamotte with a maximum application temperature of 1500°C. To obtain high rates of workability, narrow fractions of aggregate with reduced water demand should be used. Acomparative analysis of the effectiveness of superplasticizer additives was performed, and their effect on the properties of kaolin chamotte-based LCRC was evaluated. Results establish that the use of kaolin chamotte provides high strength for refractory concrete (>50 MPa after drying and first heating to operating temperatures).
