摘要
N -2 0 0 0利用减水组分与保塑组分的协同效应 ,解决了混凝土拌合物减水和坍落度损失的问题。N -2 0 0 0掺量为 0 5 %～ 1 0 % ,减水率为 15 %～ 2 8% ,使混凝土拌合物坍落度保持 2h基本不损失。N -2 0 0 0不仅改善了混凝土拌合物的工作性 ,而且与水泥具有良好的兼容性 。
N-2000 is kind of high range retarder plasticizer.The synergistic effect between the composition of a water reducer and a retarder restrains the slump loss of a fresh concrete effectively.The dosages of N-2000 are 0 5%～1 0% by mass of cement. The water reducing ratio of N-2000 is 15%～18%, which let the fresh concrete have basically no slump loss within 2 hours. N-2000 can improve not only the properties of a fresh concrete but also increase the strength of concrete, especially early strength.The experimental results have shown that N-2000 has a better compatibility with cement.
