Abstract

"ADITIVOS PARA CIMENTO DE SóLIDOS GRANDES BOMBEáVEIS". Composições de aditivos para cimento líquido exemplares têm carga de sólidos grandes o que inclui sais de metais alcalinos terrosos ou álcalis e outros componentes de aditivos de cimento. O veículo líquido é preferivelmente de natureza aquosa, apesar de que veículos não aquosos sejam possíveis, e o veículo é modificado usando um agente modificador de viscosidade e dispersante para ajudar carregar os sais e outros sólidos em quantidades de alto nível. Assim, os métodos para produzir as composições de aditivos de cimento líquido são também divulgados.
