Description
・クリンカ:成分が、CaO:約66%、SiO2:約23%、Al2O3:約5%、Fe2O3:約3%、MgO他:約3%(重量基準)となるように、石灰石、粘土、けい石、酸化鉄原料等を組み合わせて焼成したものを、クラッシャー及びグラインダーにより一次粉砕して得た、普通ポルトランドセメント用クリンカ(3.5mmふるい通過物)
・二水石膏:SO3量45.93重量%の二水石膏
・粉砕助剤:表1参照。
・クリンカ:1000g
・二水石膏:37.0g(クリンカ100重量部に対してSO3量1.7重量部)
・粉砕助剤:表1の化合物を、水硬性化合物(クリンカ)100重量部に対する添加量がグリセリン脂肪酸エステルとポリオールの合計量で0.04重量部となるように、50重量%水溶液で使用した。
株式会社セイワ技研製AXB−15を用い、ステンレスポット容量は18リットル(外径300mm)とし、ステンレスボールは30mmφ(呼び1・1/4)を30個、20mmφ(呼び3/4)を70個の合計100個のボールを使用し、ボールミルの回転数は、35rpmとした。また粉砕途中で粉砕物を一部排出しサンプリングした。
目標ブレーン値を3300±100cm2/gとし、粉砕開始から60分、75分、90分後のサンプルについてブレーン値を測定し、目標ブレーン値3300cm2/gに達する時間をマイクロソフト社製マイクロソフトエクセル2003の二次回帰式により求めた。その時間を最終到達時間(粉砕到達時間)として粉砕を終了し、セメントを得た。セメント中のグリセリン脂肪酸エステルとポリオールの合計量は、用いた原材料の量から計算して0.04%である。なおブレーン値の測定は、セメントの物理試験方法(JIS R 5201)に定められるブレーン空気透過装置を使用した。この試験での粉砕到達時間の相違は、実機レベルではより大きな差となってあらわれる。粉砕時間が短いほど粉砕性に優れることを示す。
・ジエチレングリコール:和光純薬工業(株)製、試薬(純度99%)、炭素数4
・グリセリン:和光純薬工業(株)製、試薬(純度99%)、炭素数3
・ジグリセリン:和光純薬工業(株)製、試薬、炭素数6
・グリセリンEO1モル付加物:グリセリンエチレンオキサイド(平均1モル)付加物、炭素数5
・トリグリセリン:阪本薬品工業(株)製、試薬、炭素数9
