一、前言本文研究的几种高效减水剂,没有引气性,对凝结时间无延缓作用,因此掺量可以加大使用,在一般工作度的情况下,水灰比可以大幅度降低,能得到800kgf/cm~2以上
I. INTRODUCTION Several high-range water-reducing agents studied in this paper have no air-entraining properties and have no delaying effect on the setting time. Therefore, the amount can be used more. In the case of general working conditions, the water-cement ratio can be greatly reduced. Get 800kgf/cm~2 or more
