NF与木钙复合减水剂的效果研究

Research on Compound Water reducer of NF and Ligneous Calcium Sulphonate

对ＮＦ与木钙复合减水的效果进行了试验研究，讨论了其对不同品种水泥的适应性，并对掺入复合减水剂的砼进行了坍落度损失测定．结果表明，采用ＮＦ与木钙复合减水剂效果明显优于单掺ＮＦ或木钙，既可显著改善砼性能。

The test research on the effects of compound water reducer of NF and ligneous calcium sulphonate is carried out, adaptation for different kinds of cements is discussed, and the lose of siump is determined too. The results show that the effect of water reducer of NF and ligneous calcium sulphonate is obviously better than that of NF or ligneous calcium sulphonate only, and it not only can improve the concrete function but also can reduce cost of water reducer.
