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： A dry cement mortar comprising a cement and an aggregate having a ratio of the maximum particle diameter thereof to the inner diameter of a pipe to be used for transferring the resultant cement mortar of 0.1 or less. The dry cement mortar may further comprise calcium aluminates, a gypsum, a slaked lime containing material, organic acids, fibers, a thickener, a water reducing agent, a water-absorbing agent, an alkali metal sulfate and/or an alkali metal carbonate. An accelerator may be incorporated in a wet cement mortar which has been prepared by mixing the dry cement mortar with water. The dry cement mortar can be used for providing a shooting material which allows the decrease of troubles due to a long run working with the material and the maintenance of a homogeneously mixed state of the material.
