Description
一方、従来のセメント系固化材による改良では、ハンドリング性状が良好となる程度に改良すると上述した反応によって過剰な強度が発現するという問題があった。また、セメント系固化材で改良した土は添加量にもよるがPHが高くなり過ぎるという欠点があった。
本発明に係る土質改良材は、この目的を達成するために、
ペーパスラッジ若しくは木、木炭、紙、藁、籾殻及び草木の焼却灰と、ポルトランドセメントと、高炉スラグ微粉末と、石膏とからなること、および、
上記焼却灰には吸水効果があり、かつ、その焼却灰の800℃における強熱減量が3%未満であること、および、
上記における焼却灰が15重量%から60重量%であること、および、
上記におけるポルトランドセメントが20重量%から60重量%であること、および、 上記における高炉スラグ微粉末が10重量%から40重量%であること、および、
上記における石膏が10重量%以下であること
を特徴とする。
ポルトランドセメントには早強、普通、中庸熱、低熱、エコセメントがあるが、本発明では何れのポルトランドセメントも使用することができる。
本発明において、高炉スラグ微粉末の粉末度は特に限定しないが、ブレーン比表面積で4000から6000cm2/gが望ましい。
