T梁磷渣粉C50混凝土的配制与研究

Study and preparation of C50 phosphorus slag T-beam concrete

采用普通细度磷渣粉配制出了符合设计要求的C50T梁混凝土,其合宜掺量为20%。与矿渣粉和I级粉煤灰相比,普通细度磷渣粉配制的C50T梁混凝土的力学性能、抗渗性能显示出一定的优势,早期水化热和水化放热速率降低效果最明显。

The C50 T-beam concrete was prepared from the general fineness phosphorus slag powder in the article,and the appreciate dosage ofthe phosphorus slag powder is 20%.Compared with the Fly ash concrete and the Slag concrete,it shows a few advantage in its mechanical and impermeability property,especially it can decrease the total hydration heat and lower the exothermic process obviously at the earlier stage of hydration.
