Abstract

"MISTURA E PROCESSO PARA OTIMIZAR A ADIçãO DE SUPERPLASTIFICANTE DE EO/PO EM CONCRETO CONTENDO AGREGADOS COMPREENDENDO ARGILA DE ESMECTITA". Na preparação de composições cimenteiras aquosas contendo um plastificante, tal como um plastificante contendo polímero de EO/PO, ou um plastificante contendo polímero pente de EO/PO e contendo ainda argila, tal como argila esmectita, que se expande em contato com água, a etapa de suprir um agente operativo para modificar a argila, com o que a capacidade de absorção de plastificante da argila é reduzida. Nos processos exemplificativos da invenção, o plastificante é um plastificante de EO/PO (por exemplo, oxialquileno) e, de preferência, um polímero pente de EO/PO, e o agente modificador de atividade de argila pode compreender um cátion inorgânico, um cátion orgânico, uma molécula orgânica polar capaz de ser absorvida pela argila, um dispersante de argila (tal como um polifosfato) ou uma mistura deles. Para os agentes modificadores de atividade de argila, que compreendem um cátion ou uma molécula orgânica polar, o agente é, de preferência, adicionado, à argila antes que a água seja introduzida na argila. Para os agentes dispersantes de argila e alguns cátions orgânicos, tais como aminas quaternárias (que têm uma forte afinidade para troca catiónica com a argila), o agente pode ser adicionado antes, durante ou depois da água ser introduzida na argila.
