Description
純水100g中に、N,N−ジメチルアクリルアミド(以下、「DMAA」と略記する。)20g、水膨潤性合成ヘクトライト(ビックケミー・ジャパン株式会社製、「ラポナイトRD」)4.8gを混合攪拌して分散液(a1−1)を調製した。また純水10g中に、ペルオキソ二硫酸ナトリウム(以下、「NPS」と略記する。)0.5gを混合攪拌してNPS水溶液(a2−1)を調製した。さらに純水10g中に、N,N,N’,N’−テトラメチルエチレンジアミン(以下、「TEMED」と略記する。)80μLを混合撹拌し、均一なTEMED水溶液を調製した。
次いで、分散液(a1−1)とNPS水溶液(a2−1)の質量比[(a1−1)/(a2−1)]が10となるように混合し、分散液(a−1)を得た。
モルタル平板(50mm×50mm×10mm)2枚を室温にて、あらかじめ24時間水に浸漬しておき、取り出した後に表面に付着した水滴を軽く拭き取った。この2枚のモルタル板を50mm×50mmの面同士が平行になるように並べて、その間に12mm幅のポリプロピレン製スペーサーを2ヶ挿入した。2ヶのスペーサーの距離を12mm開け、ヒドロゲルを充填する空間を作製して、モルタル板とスペーサー全体をアルミテープで固定した。次いで、上記で調製した分散液(a−1)110gに上記で調製したTEMED水溶液を全量混合し、十分に撹拌した後、2枚のモルタル間に充填して24時間静置したところ、強靱なヒドロゲルが形成され、コンクリート構造体用充填材、及びモルタル−ゲル−モルタル構造体を得た。
この構造体を用いてJIS A 1439:2010建築用シーリング剤の試験方法に準じて、引張試験を実施し、下記の基準により湿潤面付着性を評価した。
◎:0.4MPa以上
○:0.2MPa以上0.4MPa未満
×:0.2MPa未満又はゲルが脆いため測定不能
分散液(a−1)110gにTEMED水溶液を全量混合し、十分に撹拌した後、直径100mm、厚さ100mmの円柱の中心部直径26mm部分が中空になっているコンクリート円柱の中空部分に充填して24時間静置することにより、コンクリート構造体用充填材、及びゲル−コンクリート構造体を得た。
この構造体を用いて、JIS A 1404:2015建築用セメント透水試験に準じた方法で、円柱の天面全体に水で加圧し、ゲルが破損することなく、円柱の底面に水の浸入が起こらない水圧を測定し、下記の基準により評価した。
◎:0.4MPa以上
○:0.2MPa以上0.4MPa未満
×:0.2MPa未満又はゲルが脆いため測定不能
水溶性有機モノマーを、DMAAの代わりにアクリロイルモルフォリン(以下、「ACMO」と略記する。)を用いたこと以外は実施例1と同様にして、分散液(a1−2)を調製した後、コンクリート構造体用充填材、及びモルタル−ゲル−モルタル構造体を作製し、湿潤面付着性及び耐水圧性を評価した。
水膨潤性粘土鉱物を、ラポナイトRDの代わりに、ホスホン酸変性合成ヘクトライト(ビックケミー・ジャパン株式会社製、「ラポナイトRDS」)を用いたこと以外は実施例1と同様にして、分散液(a1−3)を調製した後、コンクリート構造体用充填材、及びモルタル−ゲル−モルタル構造体を作製し、湿潤面付着性及び耐水圧性を評価した。
水溶性有機モノマーを、DMAAの代わりにACMOとし、水膨潤性粘土鉱物を、ラポナイトRDの代わりに、ホスホン酸変性合成ヘクトライト(ビックケミー・ジャパン株式会社製、「ラポナイトRDS」)を用いたこと以外は実施例1と同様にして、分散液(a1−4)を調製した後、コンクリート構造体用充填材、及びモルタル−ゲル−モルタル構造体を作製し、湿潤面付着性及び耐水圧性を評価した。
純水100g中に、DMAA20g、NPS0.5gを混合攪拌し、均一溶液を調製した。さらに均一溶液にTEMED80μLを追加して混合撹拌し、室温で静置したところ、ポリN,N−ジメチルアクリルアミド水溶液が得られた。この水溶液に、ラポナイトRD4.8gを混合撹拌したところ、白色に懸濁した粘稠な液体(r−1)が得られた。
この粘稠な液体(r−1)を実施例1と同様に、2枚のモルタル間に充填し、24時間後に観察したところ、ゼリー状の非常に弱いゲルが形成されていたが、2枚のモルタルを手で持ち、わずかに延伸したところ、直ちにゲルは破壊してしまい、ゲルとコンクリートの付着性を測定することは不可能であった。
また、粘稠な液体(r−1)を実施例1と同様に、中空のコンクリート円柱に充填して24時間静置したところ、中空部分にゼリー状の非常に弱いゲルが形成されていた。このゲルをガラス棒で軽く押すと容易にゲルが破壊し、得られたゲルの耐水圧性を測定することは不可能であった。
