Description
何れも市販粉末試薬の、CaCO3及びAl2O3を用い、ヘンシェル型混合機を使用し、CaO及びAl2O3の含有モル比(CaO/Al2O3)の値が以下のA1〜A4に表す値のカルシウムアルミネートが得られるように調合した。調合物は電気炉で約1600℃(±50℃)に加熱し、当該温度で60分間保持した後、直ちに炉外に取出した。取出した加熱物の表面に冷却用窒素ガスを流速約15ml/秒で吹付けて急冷した。急冷物を全鋼製ボールミルで粉砕し、市販の分級装置にかけ、ブレーン比表面積約5000cm2/gに調整することで、粉末状のカルシウムアルミネートを得た。また、カルシウムアルミネートのガラス化率を、粉末エックス線回折装置を用い、質量がM1のカルシウムアルミネートに含まれる各鉱物の質量を内部標準法等で定量し、定量できた含有鉱物相の総和質量(M2)を算出し、残部が純ガラス相と見なし、次式でガラス化率を算出した。
ガラス化率(%)=(1−M2/M1)×100
A1;CaO及びAl2O3の含有モル比(CaO/Al2O3)が1.2のカルシウムアルミネート(ガラス化率;25%)
A2;CaO及びAl2O3の含有モル比(CaO/Al2O3)が1.4のカルシウムアルミネート(ガラス化率;46%)
A3;CaO及びAl2O3の含有モル比(CaO/Al2O3)が1.6のカルシウムアルミネート(ガラス化率;38%)
A4;CaO及びAl2O3の含有モル比(CaO/Al2O3)が2.1のカルシウムアルミネート(ガラス化率;90%)
A5;CaO及びAl2O3の含有モル比(CaO/Al2O3)が1.1のカルシウムアルミネート(ガラス化率;6%)を有効成分とする市販のアルミナセメント
前記のように作製したカルシウムアルミネート(A1〜A5)と次の各材料(B1〜E4)を用い、表2に表す配合量となるよう調合した。調合は、ホバート型ミキサを使用し、先ず、B1〜B4から選定される材料とC1〜C2から選定される材料と水を前記ミキサに投入し、E1〜4から選定される材料を使用するときはこれも併せて投入し、約1分間混合した。次いで、この混合物に他の材料を纏めて投入し、約1分間混合して埋設材を作製した。尚、B1〜B4の材料は、市販乾燥器を使用した強制乾燥による質量減少量の計測によってその含水量を予め調べ、別添加した水の量と併せて表1で表す埋設材の含水量とした。
B2;生コンクリートプラントで発生したモルタルスラッジ(含水率;約15質量%、含有固型粒子の最大粒径3mm、未水和セメント含有率<0.1質量%)
B3;生コンクリート攪拌タンクの洗浄で発生した泥水(含水率;約40質量%、含有固型粒子の最大粒径1mm、未水和セメント含有率<0.1質量%)
B4;石灰石系細骨材(石灰石砕砂、50質量%篩通過時の平均粒径約3mm、含水率<0.1質量%)
C1;普通ポルトランドセメント(市販品、ブレーン比表面積;3350cm2/g)
C2;高炉セメントB種(市販品、ブレーン比表面積;3750cm2/g)
D;ポリカルボン酸縮重合物を有効成分とする高性能AE減水剤(市販品、顆粒状)
E1;II型無水石膏(市販品、ブレーン比表面積;4000cm2/g)
E2;炭酸リチウム(市販試薬)
E3;炭酸ナトリウム(市販試薬)
E4;クエン酸(市販試薬)
作製した埋設材に対し、流動性の評価として、作製直後の20℃(±1℃)でのフロー値をJHS 313−1999に規定する「シリンダー法による測定」に準拠した方法で測定した。尚、流動性が非常に乏しく、この方法ではフロー値が測定できなかったものを測定不良とし、以下の評価対象から外した。
