摘要
文章以南钦铁路南宁段良庆制梁场工程为依托,结合混凝土配合比设计技术条件、参数及混凝土配合比和性能,介绍了在现场预制梁中使用聚羧酸系高性能减水剂的应用效果。
Taking the construction of beam manufacture yard in Nan-Qin Railway Nanning segment as an example,and combined with the technical requirement of cocrete design,index and performance of concrete mixture ratio,the article introduces the effect of high performance polycarboxylic acid type water reducing agent on producing pre-made beam.
