Werner's theory of coordination and some related theories of 3D chemistry were employed to study molecular structure and characteristics of inorganic and organic retarding admixtures.
Werner)配位学说和立体化学有关理论,分析研究了无机、有机缓凝外加剂的分子结构和特征,发现缓凝外加剂都是配位化合物,化学本质是配位键。
The new super setting retarder product(HLC-NAF2) was developed according to the construction characteristics of the bored lock piles,which features in higher dispersiveness and less slump loss,and the setting time can reach 60～80 hours when this product is contained in the concrete.
针对钻孔咬合桩的施工特点配制出新型的混凝土超缓凝外加剂(HLC-NAF2),该产品具有较高的分散性能,掺加后混凝土坍落度经时损失小,缓凝时间可达60~80h,在南京地铁2号线深基坑围护工程钻孔咬合桩施工中得到了成功应用。
