Abstract

resumo ?redução de água de baixa a média gama com o uso de polímeros de policarboxilato em pente? a presente invenção refere-se a métodos para plastificar misturas cimentícias que têm razão entre água/cimento relativamente alta (pelo menos 0,40 ou mais) que são surpreendentemente aprimoradas em termos de eficiência de dosagem, em comparação aos polímeros de policarboxilato (superplastificantes), quando o polímero de policarboxilato é formado de constituintes de monômero especificamente selecionados dimensionados de maneira particularmente pequena: (a) 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 grupos de óxido de etileno linear e "p é 5 a 23, mais preferencialmente, 5 a 15; (b) ácido carboxílico insaturado representado por (r5)(r7)c=c(r6)(c(o)om), em que m representa um metal alcalino, sendo que a razão entre o componente a e o componente b é 20:80 a 50:50; e, opcionalmente, (c) um monômero hidrofílico representado por (r8)(r9)c=c(r10)(cx), em que r8, r9 e r10, cada um, representam hidrogênio o grupo metila, e x representa c(o)nh2, c(o)nhr11, c(o)nr12r13, so3h, c6h4so3h ou c(o)nhc(ch3)2ch2so3h ou misturas dos mesmos, em que r11, r12 e r13, cada um, representam um grupo alquila c1 a c5.
