Abstract
FORNECIMENTO DE RESISTêNCIA AO CONGELAMENTO E DESCONGELAMENTO PARA COMPOSIçõES DE CIMENTOS. A presente invenção refere-se à composição de cimento moldado úmido de durabilidade melhorada contra congelamento-descongelamento que usa produção in situ pelos aditivos de geração de gás e opcionalmente microesferas poliméricas que são misturadas diretamente na mistura. Os aditivos de geração de gás e microesferas poliméricas provêem espaços de vazio na matriz do material, e tais espaços vazios atuam para aumentar a durabilidade em congelamento - descongelamento do material.
