NEUTRALIZATION SUPPRESSION OF CEMENT-BASED CURED PRODUCT AND CHLORIDE ION PERMEATION SUPPRESSION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a method effective for both neutralization suppression and chloride ion permeation suppression, in a problem of neutralization and salt damage of a cement-based cured product in a concrete structure such as a reinforced concrete structure including a steel material.;SOLUTION: A method includes previously adding alginate such as sodium alginate and potassium alginate to a hydraulic composition including Portland cement and blast furnace cement as mainly containing cement, and mixing water and an aggregate to the mixed substance to subject the mixed substance to a hydration reaction so as to suppress neutralization and chlorine ion permeation of a cured product after curing.;SELECTED DRAWING: None;COPYRIGHT: (C)2018,JPO&INPIT
