である。
実施例1
けい酸質原料としてケイ石粉末28質量部、石灰質原料として消石灰27質量部および補強繊維としてパルプ5質量部、さらに未膨張バーミキュライト40質量部を出発原料として、これらに水を添加して混合し固形分約12%のスラリーとし、抄造機により生シートを形成させた後,オートクレーブ中(160〜180℃、約10時間)で加圧養生させ、ついで80℃未満で所定の含水率になるまで乾燥させ、けい酸カルシウムボード(30cm×30cm×6mm)を得た。
実施例2
実施例1において、けい酸カルシウムボード(30cm×30cm×6mm)を得るための仕上げ加工時に発生した研磨粉体(粒径1mm以下)を集めて、これをそのまま造粒する以外は実施例1と同様にして、目的とする造粒(球状)人工土壌を得た。その粒径は約2mmであり、硬度は約1kg/cm2であった。この造粒人工土壌はけい酸質肥料としてそのまま用いることができた。
比較例1
実施例1において、ピンミルを用いて粉砕する際に、粉砕を途中で停止して、大部分のパルプの長さが25〜40mmとした以外は、実施例1と同様にして、目的とする造粒(球状)人工土壌を得た。その粒径は約2mmであり、硬度は約0.05kg/cm2であった。
