Abstract

métodos para plastificar misturas cimentícias tendo uma proporção de água/cimento relativamente alta (pelo menos 0,40 ou maior) são surpreendentemente melhorados em termos de eficiência de dosagem, comparados a polímeros de policarboxilato superplastificante convencionais, quando o copolímero de carboxilato do tipo pente é formado a partir de duas cadeias laterais poliéter diferentes, especificamente selecionado de constituintes de monômero: (a) primeiro monômero de polioxialquileno representado pela fórmula estrutural (r1)(r3)c=c(r2)((ch2)m(co)no(ch2)o(ao)pr4) em que (ao)p representa óxido de alquileno linear e p é um número inteiro de 5 a 23; (b) segundo monômero de polioxialquileno representado pela fórmula estrutural (r1) (r3)c=c(r2)((ch2)m(co)no(ch2)o(ao)qr4) em que (ao)q representa grupos óxido de alquileno linear e q é um número inteiro de 20 a 200; (c) monômero de ácido carboxílico insaturado representado por (r5)(r7)c=c(r6)(c(o)om) em que m representa um metal alcalino, e a razão de componente a para componente b é 20:80 a 50:50; e, opcionalmente, (d) um monômero solúvel em água representado por (r8)(r9)c=c(r10) (x) em que r8, r9 e r10 representam hidrogênio ou grupo metila, e x representa c(o)nh2, c(o)nhr11, c(o)nr12r13, or14, so3h, c6h4so3h ou c(o)nhc(ch3)2ch2so3h, ou mistura destes, em que r11, r12, r13 e r14 representam um grupo alquila c1 a c5.
