  • CO2 IMMOBILIZATION MATERIAL AND METHOD FOR PRODUCING CO2 IMMOBILIZATION PRODUCT
    Publication number: 20240335814
    Abstract: There are provided a CO2 immobilization material including one kind or two or more kinds of non-hydraulic compound selected from the group consisting of ?-2CaO·SiO2, 3CaO·2SiO2, ?-CaO·SiO2, and calcium magnesium silicate, in which the CO2 immobilization material contains Li, and a content percentage of the Li is 0.001 to 1.0% by mass in terms of oxide; and a method for producing a CO2 immobilization product including subjecting the CO2 immobilization material to a carbonation treatment at 75° C. or lower and/or 50% RH or higher.

  • CEMENT ADMIXTURE, EXPANSION MATERIAL, AND CEMENT COMPOSITION
    Publication number: 20230242448
    Abstract: A cement admixture containing free lime, gypsum, Ye’elimite, and ternesite, wherein the cement admixture has a mass ratio of the Ye’elimite to the ternesite (Ye?elimite/ternesite) of from 0.5 to 40. The cement admixture contains 20 to 80 mass% of the free lime. The cement admixture has a total mass ratio of the free lime and the gypsum anhydride to the ternesite ((free lime + gypsum anhydride)/ternesite) from 20 to 90. An expansive material which contains the cement admixture. A cement composition which contains the cement admixture.

  • CEMENT ADMIXTURE AND CEMENT COMPOSITION
    Publication number: 20230202921
    Abstract: A cement admixture containing one kind or two or more kinds of non-hydraulic compound(s) selected from ?-2CaO·SiO2, 3CaO·2SiO2, ?-CaO·SiO2, and calcium magnesium silicate, wherein the non-hydraulic compound contains Li, and the content rate of the Li is 0.001 to 1.0% by mass in terms of oxide. Such admixtures may contain, as chemical components, 0.001 to 1.0 parts by mass of Li2O, 45 to 70 parts by mass of CaO, 30 to 55 parts by mass of SiO2, and 0 to 10 parts by mass of Al2O3 in 100 parts by mass of the cement admixture.
