摘　　要：为了解决重庆地区高强陶粒混凝土的设计与制备技术难题,该文通过分析陶粒混凝土的高强化技术途径,经过试验,提出了一种高强陶粒混凝土的设计方法和制备技术,关键工艺参数预湿时间应大于24h,搅拌时间应不小于3min;分析研究了所制备陶粒混凝土的性能,结果为:陶粒混凝土的坍落度和抗压强度满足预拌生产和泵送施工的要求,收缩和抗渗性能优于同强度等级的普通混凝土。In order to conquer design and preparation technology problem of high-strength ceramsite concrete in Chongqing, technological approaches through which ceramsite concrete obtains high strength are analyzed. On this basis, a design method and preparation technology for high-strength ceram- site concrete are come up with by experiment. The key technological parameters： pre-wetting time should be more than 24 hours and mixing time should be not less than 3 minutes. Performances of ceramsite concrete are also analyzed and studied. The results show that the slump and pressure resistance of ceramsite concrete meet the requirement of ready-mixed production and pumping construction with better shrinkage and impermeability performances than ordinary concrete.
