Description
また、特許文献4には、シリカ、ライム、分散剤の記載はあるが、シリカを含有する懸濁液、ライムを含有する懸濁液のそれぞれに分散剤を含有することの記載はない。
しかしながら、特許文献5に記載の発明は、平均粒径を1μm以下とするために、上記のように、超微粒子材料(シリカフュームおよび消石灰)の解砕、攪拌、分散剤の添加を繰り返し行うという複雑な工程を経なければならないという問題があり、また、一次粒子に近い高分散化低粘性超微粒子グラウトを作製するためには、解砕方式として、ボール(ビーズ)を媒体にしてスラリーをミキサーで撹拌するという方式を適用する必要があった(段落[0021])。そして、レーザー回折/散乱式粒度分析装置を用いて測定する場合には、通常はJIS R 1629に記載の通り、前処理として超音波分散処理を行うものであるから、超音波分散処理を行うことなくレーザー回折/散乱式粒度分析装置を用いて測定した場合の平均粒径は明らかではない。また、超微粒子材料として、シリカフューム以外の微細シリカ粉末についての記載はなく、高分散化低粘性超微粒子スラリーを注入材とした場合の耐久性についても記載されていない。

金属シリコン粉末を水に分散させたスラリーを火炎中に噴射し燃焼、酸化させる方法で製造した微粒子シリカは、分散性が良く、最初に分散剤を添加しなくても水に分散させることができるから、後から分散剤を添加しても良い。この水への分散性は、シラノール基濃度が関係していると推定される。
