Abstract

"MISTURA DE CONCRETO QUE PRODUZ CONCRETO COM ALTA RESISTêNCIA EM DENSIDADE VARIADA, MéTODO PARA PRODUZIR A MISTURA E O CONCRETO, E USO DE UM ADITIVO ANIÈNICO". A presente invenção se refere a uma mistura de concreto aquoso tendo um volume de poro de ar entre 10 e 85%, preferencialmente, entre 20 e 85%. Após a cura, obtêm-se um concreto com densidade uniforme e alta resistência. Isto é conseguido pelo uso de um composto ativo em superfície aquoso aniónico contendo dois grupamentos de ácido sulfónico da fórmula geral ( I ) ( R )~ m~-R~ 1~-( SO~ 3~M )~ 2~, em que R é um grupo alifático tendo de 4 a 20 átomos de carbono, m é um número 1 ou 2, a soma do número de átomos de carbono no grupo ou nos grupos R sendo de 6 a 30, R, é um grupo aromático contendo pelo menos 2 anéis aromáticos e de 10 a 20 átomos de carbono, e M é um cátion ou hidrogênio. O composto aniónico tem um efeito de arraste de ar e melhora a homogeneidade da mistura de concreto.
