摘要： PROBLEM TO BE SOLVED: To provide a grout material having a performance enabling to be filled over the whole length of a sheath without causing a void when after giving tension to a PC (prestressed concrete) steel material used for introducing prestress, the sheath which is to be filled with the grout material for protecting the PC steel material, is arranged in a wave shape within the same vertical plane in the prestressed concrete-made structure.
SOLUTION: A thixotropic property, such that the viscosity is high to such an extent that filling failures such as a flow leaving an unfilled part do not occur under atmospheric pressure, and the viscosity under pressure becomes lower than that under atmospheric pressure to such an extent that the pouring is possible when the pressure is raised from the atmospheric pressure, is given to the grout material by adding 10-15% silica fume to the total weight of powder into the grout material containing water and cement as main ingredient. The viscosity of the grout material is controlled concretely so that the flow value is 100-200 mm and the time of flow of the grout material when pressurized to 0.1 MPa from the atmospheric pressure is 0.5-3.0 sec.

摘要： PROBLEM TO BE SOLVED: To quantitatively evaluate thixotropy property for a grout material having thixotropy property having high viscosity in a non-pressurizing state and viscosity in a pressurizing state lower than viscosity in the non-pressurizing state. SOLUTION: This property evaluating device 1 is structured with a funnel 2, filled with the grout material, having a cock 3 for its open/close operation at a flow-out port 2a of a lower end, a sealed vessel 4 for storing the funnel 2, a pipe 5 for feeding compressed air into the sealed vessel 4 and a bed plate 6 with a leg 61 for supporting the sealed vessel 4. Compressed air is feeded into the sealed vessel 4 through the pipe 5 and the property evaluation device 1 is used to measure flow-down time of every pressure in the sealed vessel 4 which is the time that the grout material in the funnel 2 takes to completely flow down from the flow-out port 2a.

摘要： PROBLEM TO BE SOLVED: To provide a cross section repairing material improving workability such as trowel finishing while restricting a content of a polymer, excelling in strength and durability without least shrinkage due to aridity for a long period of time. SOLUTION: The cross section repairing material having thixotropy, and a nearly zero of shrinkage due to aridity is made by blending a cement family cross section repairing material with silica fume and urea, adding water for kneading, a high performance water reducing agent and the like, and kneading. The cross section repairing material is improved in workability such as trowel finishing owing to having thixotropy, does not sag in case of a thick application of 50-160 mm extent, is easy to be evenly extended in case of a thin application of 1 mm extent, and has an application field broader than a conventional cross section repairing material.

摘要： PROBLEM TO BE SOLVED: To provide a grout material with property such that the grout material can be filled into a whole length of a sheath without causing a void when after giving a tension to a PC (prestress concrete) steel material used for introducing prestress, the sheath which is to be filled with the grout material for protecting the PC steel material, is arranged in a wave shape within the same vertical plane in a prestress concrete structure.
SOLUTION: A thixotropic property such that the viscosity is high so as not to cause filling failures such as a flow leaving an unfilled part under atmospheric pressure, and the viscosity under pressure becomes lower than that under atmospheric pressure in such a degree that the injection is possible when the pressure is raised from the atmospheric pressure, is given to the grout material by adding additives such as an argillaceous additive to the grout material including water and cement as main raw materials. Concretely, the viscosity of the grout material is controlled so that the flow value is 100-200 mm, and the flow down time of the grout material becomes 0.5-3.0 sec when a pressure of 0.1 MPa is added.
