    摘要： PROBLEM TO BE SOLVED: To provide quick-hardening mortar for spraying not drooping even if increasing a water binder ratio, and having small electric resistance and small contraction, and to provide a corrosion prevention method by the same, for further reducing the contraction, maintaining the small electric resistance for a long period, and not disturbing permeation of chlorine gas or the like.SOLUTION: The quick-hardening mortar for spraying having the small electric resistance uses a quick-hardening mortar composition wherein a binder containing cement and a quick-hardening material, a fine aggregate, a water reducing agent, and water are blended, can be obtained by adding aluminum sulfate to a quick-hardening mortar having a no-tapping mortar flow value of 200-320 mm prepared by use of a mortar composition having the water binder ratio of 30-55% and a unit water amount of 250-400 kg/m, and has a contraction amount ≤-800×10. A hardened body of the quick-hardening mortar for spraying has electric resistivity ≤100 kΩcm. A quick-hardening mortar hardened body is formed by coating an organic-inorganic composite coating-film curing agent on the surface of the hardened body of the quick-hardening mortar for spraying. The corrosion prevention method for steel material inside a concrete structure uses the quick-hardening mortar hardened body.

    摘要： PROBLEM TO BE SOLVED: To provide mortar for a plasterer which eliminates drooping even if a ratio of water to a binder is increased and has small electric resistance and low shrinkage and to provide a corrosion prevention method using the mortar for the plasterer which further reduces the shrinkage, keeps the electric resistance small for a long term and does not prevent the penetration of chlorine gas and the like.
    SOLUTION: The mortar for the plasterer is made by using a mortar composition blended with the binder containing cement, a fine aggregate, a water reducing agent and water and is obtained by kneading a mixture of mortar which is prepared by using a mortar blend having a ratio of water to the binder of 35-55% and a unit water amount of 250-400 kg/m
    3 and which has a no-tapping mortar flow value of 200-320 mm and a water soluble acrylic polymer and aluminum sulfate. A hardened body using the mortar for the plasterer has an electric resistivity of 100 kΩ cm or less and a shrinkage amount of -800×10
    -6 or less. A mortar hardened body is made by coating an organic-inorganic composite coating film curing agent on the surface of the hardened body of the mortar for the plasterer. In a corrosion prevention method for a steel material in a concrete structure, the hardened body of the mortar for the plasterer or the mortar hardened body is used.
