水下不分散混凝土水下不分散混凝土（ＮＤＣ），亦称无冷缝水下混凝土，是国外近１０年问世的一种新型建筑工程材料。国外学术界、工程界称为“理想的划时代的全新滋凝土”。其机理是将具有特定性能的聚合物（ＰＭＡ）加入新拌制的普通混凝土中，达到极大地提高混凝土粘聚...
Underwater non-dispersed concrete underwater non-dispersed concrete (NDC), also known as non-cold-seam underwater concrete, is a new type of construction engineering material that has been introduced abroad for nearly 10 years. Foreign academic circles and engineering circles are called “ideal epoch-making new trophic soils.” The mechanism is to add polymer (PMA) with specific properties into fresh concrete to increase the concrete’s cohesion...
