CAPSULE ADMIXTURE
To provide a capsule admixture that is added to a cement composition and is useful for preventing the neutralization, without the need for ex post countermeasures thereagainst.SOLUTION: A capsule admixture 1 is added to a concrete product. The capsule admixture 1 has a shell part 2 that holds a re-alkalization solution 3 inside, holds the re-alkalization solution 3 at an alkaline pH of a predetermined value or more, and disintegrates in the other pH areas to leak the re-alkalization solution 3. The pH value at which the shell part 2 disintegrates is set to 8-10 in pH.SELECTED DRAWING: Figure 1
【課題】事後的な施工を必要としない、中性化抑制対策として有用なセメント組成物に添加されるカプセル混和材を提供する。【解決手段】コンクリート生成物に添加されるカプセル混和材1であって、内部に再アルカリ化溶液3を保持し、所定値以上のアルカリ性のpHでは再アルカリ化溶液3を保持し、他のpH領域では崩壊して再アルカリ化溶液3を漏出させる殻部2を有する。また、上記殻部2が崩壊するpH値をpH8~pH10に設定する。【選択図】図1
