Abstract

COMPOSIÇÃO HIDRÁULICA, MATERIAL MISTURADO A UMA COMPOSIÇÃO HIDRÁULICA, E CORPO ENDURECIDO. A presente invenção refere-se a uma composição hidráulica a qual é capaz de conter e armazenar de maneira estável o CO2 recuperado a partir da atmosfera, bem como ao mesmo tempo reduzindo o custo; e a um corpo endurecido que é formado por essa composição hidráulica. A presente invenção é uma composição hidráulica contendo carbonato de cálcio. Uma proporção do carbonato de cálcio contido nos materiais se situa em uma faixa de 30% em massa a 95% em massa. Além disso, a composição hidráulica contém no mínimo um material selecionado entre escória de alto forno, um aditivo expansivo, cal apagada, cal viva, cinzas volantes e cimento Portland. Nota-se que, no caso de conter cimento Portland, uma proporção do cimento Portland nos materiais, com exceção do carbonato de cálcio, é de 30% em massa. Além disso, no caso de conter um aditivo expansivo, uma proporção do aditivo expansivo nos materiais é de 2 a 9% em massa ou menos.
