FLUIDITY AND HYDRATION PROPERTY OF HIGH INTERSTITIAL PHASE CEMENT

高間隙相型セメントペーストの流動性と水和特性

Recently, the amount of cement production has been decreasing. However usage of recycled resources from the other industry is required to be increased in the process of cement production. In general, recycled resources have larger alumina composition than cement material. Therefore, the fluidity of cement paste is worse. In this study, the authors investigate high interstitial phase (high C3A and C4AF) cement containing large amount of recycled resource. Gypsum and lime stone powder (LSP) were added to improve the fluidity. It was revealed that the fluidity of this cement was magnificently improved by adding 4mass％ gypsum and 10mass％ LSP. This is because the initial hydration of this cement got smaller.現在セメントの生産量は減少傾向にあるが、他産業からの廃棄物の受け入れ量は増加していく必要がある。しかし廃棄物はセメントと比較してアルミナ成分が多く、廃棄物使用量の増加時には、セメントペーストの流動性悪化が問題となる。本研究では3CaO・Al₂O₃と4CaO・Al₂O₃・Fe₂O₃を増加させたセメントクリンカーに対し、石灰石微粉末やセッコウの添加量を調製し、流動性を改善した。その結果、石灰石微粉末量を10％、SO₃量を4％とした際、セメントの初期の水和反応が抑えられ、既存のセメントペーストと近い流動性となることが分かった。
