Description
2Al+6H+→2Al3++3H2 (式1)
2Al+2OH−+2H2O→2AlO2 −+3H2 (式2)
1)スルホ・アルミナセメントのスラリの間隙溶液のpHは(この鉱物集合体が石膏を含む限り10〜11に含まれる)、ポルトランドセメントのスラリのpH(13超)より低く、これによりアルミニウムの腐食速度が低下する。
2)スルホ・アルミナ結合材の化学的水分要求(セメントの無水相を完全に水和するために必要な水の量)は、その初期石膏含有量と共に増加するが、ポルトランドセメントよりも大きい(非特許文献3)。したがって、高度な水和レベルに達したスルホ・アルミナセメントのスラリ中の残留水分量は減少し、したがって長期のアルミニウム腐食が制限される。
MgO+(NH4)2HPO4+5H2O→NH4MgPO4・6H2O+NH3 (式3)
MgO+KH2PO4+5H2O→MgKPO4・6H2O (式4)
セメントマトリックスにおけるアルミニウムの腐食による水素の発生が、既存の溶液と比較して低減されること、
結合材の反応が制御下にあること(ビカー始発凝結時間3時間超、ビカー終結凝結時間24時間未満)、
材料混練後、12.5mm継手付きマーシュコーンの通過に十分な流動性を有すること、
材料凝結の24時間後、ブリーディングが全くないこと、
結合材の硬化中の自己発熱が材料の劣化を引き起こさないこと(例えば混合/バッチ処理水気化後のクラッキングやマクロ気孔の生成など)、
90日間の室温での水中養生後、20MPaを超える圧縮強度を有するようになること、
硬化した材料が、水中または空気中で室温に保たれているときに、その完全性に(クラックの結果として)影響を与えうる膨張も収縮もしないこと、
5〜9の間隙溶液pHを有すること。
