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.
