description | Islak çimento kompozisyonuna daha yüksek plastik özelligi, zaman içinde daha düsük topak kaybi ve bu tipte polimetik tiplerle baglantili hava girme problemi olmadan su azaltma özelligi kazandiran polimerik katki maddesi. Süperplastiklestiriciler, etilenik olarak doymamis karboksilik asitlerin polimerizasyonu ile olusan bir karbon omurgasina sahiptir, omurga; karboksilik asit asi bölgeleri içerir bunlar kovalent olarak a) hava atici islevli yan zincirlere, bunlar genel formül R4-(OA2)x-Q-'nun birinci polioksialkilen gruplari, burada Q=O ya da NH'tir; A2=C1-C10 alkilen; X=l ila 200; ve R4=C1-C10 alkildir, b) genel formül R5-O(A3O)y-(A3)p-N-'nin ikinci polioksialkilen gruplari, burada A3=C1-C10alkilen; y=1 ila 200; p=1 ila 50; ve R5=C1-C10alkil'dir.
Polymeric additives for hydraulic cement compositions which impart to the wet cement composition greater plasticity, lower slumploss over time, and water reduction capability without the problems of air entrainment associated with prior polymeric additives of this type. The superplasticizers have a carbon backbone formed by polymerization of ethylenically-unsaturated carboxylic acids, the backbone comprising carboxylic acid grafting sites to which are covalently attached a) air detraining functional side chains, which are first polyoxyalkylene groups of the general formula: R -(OA )x-Q-, wherein Q = O or NH; A = C1-C10alkylene; x = 1 to 200; and R = C1-C10alkyl, and b) second polyoxyalkylene groups of the general formula R -O-(A O)y-(A )p-N=, wherein A = C1-C10alkylene; y = 1 to 200; p = 1 to 50; and R = C1-C10alkyl. |
