    Abstract: This invention provides a concrete having excellent exploding resistance, comprising a fiber as one constituent material, wherein said concrete has a compressive strength of 50 N/mm2 or more, a bending strength of 6 N/mm2 or more, and a ratio of the bending strength to the compressive strength is 15 or less. Upon explosion of an explosive material near a structure, a part of the structure is separated by explosion energy. In general, the separation of the structure on the side opposite to the side facing explosion is larger than that of the side facing explosion, it could trigger collapse of concrete, and the separation on this side has a larger risk of injuring persons within the structure. Since the present invention has the effect of reducing a separated volume, it can be used for various structures as a concrete for lifesaving or for preventing the collapse of the structure.

    Abstract: Flowable concrete mixtures have an aqueous foam admixture mixed therein to give the concrete mixture desired strength, flowability, and density. The concrete mixtures include a hydration stabilizer to stabilize the aqueous foam. The hydration stabilizer inhibits the reaction between the hydraulic cement and the water in the aqueous foam. The aqueous foam can be further stabilized using a fluorochemical surfactant. Preferred fluorochemical surfactants comprise an oligomer having at least one hydrophilic nonionic monomer and at least one hydrophilic anionic monomer.

    Abstract: The invention relates to a fiber/cement composite, the cementitious matrix of which has a water/binder ratio of less than 0.25 and consisting of cement, aggregate elements, fine pozzolanic elements and a plasticizer.The reinforcement consists of three types of fiber: a) metal fibers having a length of between 15 and 25 mm and a diameter of between 0.25 and 0.3 mm, in a percentage by volume of between 0.5 and 3%; b) metal fibers having a length of between 5 and 10 mm and a diameter of between 0.15 and 0.2 mm, in a percentage of between 4 and 7%; and c) 1.5 to 5% of short metal fibers having a length of less than 3 mm.The strength of this composite in uniaxial tension is greater than or equal to 30 MPa. It exhibits positive work-hardening and ductile behavior in uniaxial tension.
