  • Process for producing a concrete and a mortar
    Patent number: 7018466
    Abstract: A concrete admixture or a mortar admixture which is obtained by mixing a silicate with an acid in the presence of water and then solidifying the mixture. It is preferable that the silicate is sodium silicate and the acid is a carboxylic acid. This admixture can improve a tensile strength of a concrete or a mortar. Since a concrete or a mortar containing the admixture, cement, an aggregate and water is high in tensile strength, it can advantageously be used in various concrete structures, concrete products or mortar products.
    Type: Grant
    Filed: January 10, 2005
    Date of Patent: March 28, 2006
    Assignees: Tobishima Corporation, Aston Co., Ltd.
