摘要： The invention provides an expansive material that allows for large expansion of concrete at a material age of 2 to 7 days after pouring and permits concrete to have higher initial compressive strength and makes sure good storage stability, and a process for preparing that expansive material. The invention provides an expansive material and a process for preparing that expansive material, characterized in that clinker or pulverized clinker containing free lime, a hydraulic compound and calcium sulfate anhydrite is heat treated in a carbon dioxide gas atmosphere to form calcium carbonate in it. Preferably, the expansive material contains a particle in which the free lime, hydraulic compound, calcium sulfate anhydrite and calcium carbonate are all present; the content of calcium carbonate is 0.5 to 10% by mass; and the expansive material has a Blaine's specific surface area of 1,500 to 90,000 cm 2 /g. The expansive material is blended with cement into a cement composition. The preparation conditions are preferably a carbon dioxide gas flow rate of 0.01 to 0.1 L/min. and a temperature of 200 to 800°C, under which conditions there is calcium carbonate formed.

摘要： The invention provides a cement composite and its formation method, in which a specific substance block agent is coated on a hardened cement product, thereby effectively blocking off substances responsible for corrosion and cracking, holding back carbonation of the hardened cement product and making the hardened cement product less likely to turn white. In the cement composite, a hardened cement product is coated with a substance block agent composed chiefly of an aqueous dispersion of synthetic resin, a swelling clay mineral and a pigment. The swelling clay mineral is a swelling clay mineral containing fluorine; the substance block agent contains a water-soluble resin; and the substance block agent is coated on the hardened cement product in an amount of 50 to 500 g/m 2 . The invention also provides a cement composite formation method, characterized in that the substance block agent is coated on the surface of the hardened cement product.

摘要： An cement admixture comprising one or more non−hydraulic compounds selected from the group consisting of Ϝ−2CaO · SiO 2 , Α−CaO · SiO 2 and calcium magnesium silicate; a cement composition comprising the cement admixture; and a method for suppressing carbonation which uses the cement admixture or the cement composition. The method exerts significant effect of suppressing carbonation particularly when it is applied to a portland blast−furnace slag cement, and the cement composition results in the effective use of a slag from steelmaking, allows the reduction of the amount of a clinker to be compounded, is environmentally friendly, and is suitable as a cement complying with the EN standard which is widely used in civil engineering and building industries.

摘要： To provide carbonation curing equipment, a carbonated concrete producing method and a carbon dioxide fixing method with which it is possible to economically mass-produce the carbonated concrete and to greatly reduce the carbon dioxide emissions from a thermal power plant. Carbonation curing equipment 10 used for producing the carbonated concrete is equipped with a flue gas circulator 12 for supplying flue gas exhausted from a thermal power plant 1 to a carbonation curing tank 11 and for circulating the flue gas in the carbonation curing tank 11, in order to utilize the thermal power plant 1 as a carbon dioxide source for carbonation-curing an object to be cured which is held in the carbonation curing tank 11 having a shielded internal space. The flue gas exhausted from the thermal power plant 1 is supplied to the inside of the carbonation curing tank 11 without regulating the concentration and the flow rate, and the object to be cured held in the carbonation curing tank 11 is carbonation-cured.

摘要： A cement admixture which is reduced in the burden to be imposed on the environment, is effective in diminishing hexavalent chromium, is reduced in slump loss and heat of hydration, is less apt to be neutralized, and can be reduced in self-shrinkage. The cement admixture comprises an air-cooled blast furnace slag powder which consists mainly of a melilite and has a CO2 absorption of 2% or higher and an ignition loss of 5% or lower. In the powder, the content of sulfur not in the form of sulfuric acid is 0.5% or higher and/or the concentration of non-sulfuric-acid-form sulfur which dissolves away is 100 mg/L or higher. Preferably, the powder has a degree of vitrification of 30% or lower, a melilite lattice constant, a, of 7.73 to 7.82, and/or a Blaine specific surface area of 4,000 cm2/g or larger.
