Abstract

composição de pasta de cimento substancialmente livre de água. a presente invenção se refere a pastas de cimento hidráulico substancialmente livres de água que permanecem estáveis em prateleira durante períodos de tempo prolongados, por exemplo, 100 dias à temperatura ambiente. as pastas de cimento substancialmente livres de água compreendem uma mistura de solvente eutético profundo de um componente de carreador orgânico polar, tal como um doador de hidrogênio como um poliol, associado a um componente que contém cátion anidro, e um cimento hidráulico, preferencialmente, um cimento de aluminato ou cimento de sulfoaluminato. uma mistura de solvente eutético profundo preferencial compreende k2co3 e glicerol em razões molares de 1:1 a 1:6. as pastas de cimento são ativadas pela simples adição de água ou polímeros aquosos para formar composições de pega fina.
