采用高标号水泥、高效减水剂和优质的耐火骨料 ,经过科学计算、设计、配制成高强耐热混凝土 ,并将其应用在隧道窑窑车上。经三年使用效果表明 :其不仅能满足耐热性能要求 ,抗冲击性和抗磨损性明显优于粘土耐火砖和普通耐热混凝土 ,而且维修费用低 ,使用寿命长。
The use of high-grade cement, superplasticizer and high-quality refractory aggregate, after scientific calculations, design, preparation of high strength heat-resistant concrete, and its application in tunnel kiln car. After three years of use results show that: not only to meet the requirements of heat resistance, impact resistance and wear resistance significantly better than clay refractory bricks and ordinary heat-resistant concrete, and low maintenance costs and long service life.
