| 摘 要： | 重晶石防辐射混凝土因浆骨密度差异大,容易出现离析、分层等现象,这不仅使其工作性能不容易满足泵送施工要求,而且其密实性、匀质性也受到影响,二者矛盾较难统一.成都某核动力研究所重晶石防辐射混凝土项目,要求采用密度≥3 600 kg/m3的C25重晶石防辐射混凝土进行泵送施工,在成都地区尚属首例.针对该项目开展重晶石防辐射泵...

| Abstract: | Barite anti-radiation concrete was easy to segregation and delamination because of the differences between slurry and aggregates,it made not only the workability of barite concrete can not meet the pumping construction requirements,but also the compactibility and homogenity of concrete was affected,the conflicts between them was difficult to unity.One barite concrete project for a nuclear power in Chengdu required using C25 barite concrete with apparent density more than 3 600 kg/m3 for pumping construction... |
