Description
粉砕助剤として、プロピレングリコール濃度40%、絶対粘度270mPa・sの回収不凍液を用いた。比較用として、凝集沈殿処理をした回収不凍液、ジエチレングリコールも含めた。また、セメントクリンカは太平洋セメント(株)製、石膏には火力発電所で回収された排脱二水石膏を用いた。
セメントクリンカの粉砕は、3kg/バッチのボールミルにより行った。5mm以下に粗粉砕した普通ポルトランドセメントクリンカ3kg、及び出来上がりのセメントのSO3量が2.0質量%となるように計算された量の石膏を、上記ボールミルに投入し、目標ブレーン比表面積が3200±100cm2/gとなるように粉砕し、セメントを調製した。この時、目標ブレーン比表面積に到達するまでの粉砕時間(分)を記録した。試料の添加量は、クリンカ100質量部に対して、各々0.02質量部とした。
