CaCO3[Merck、分析グレード]、CaSO4[Merck、分析グレード]及び石英粉末[Merck、分析グレード]の化学量論量の混合物を、1,100℃で1時間燃焼し、その後急冷し、そして二尾、1,100℃で1時間燃焼し、急冷した。
原料混合物は、45重量%の石灰石(K1)+27重量%のFA1、20重量%のMicroA及び8重量%の石英粉末(Merck、分析グレード)を含有していた。原料粉末を1,100℃で焼結し、そして焼結後、温度を、1,000℃から850℃へ約35分かけて低下させる、焼き鈍しのための冷却プログラムを経させた。クリンカーはその後、空気に曝すことによって急速に冷却された。
原料混合物は、58重量%のK1+8重量%のMK、24重量%のMicroA及び10重量%の石英粉末(Merck、分析グレード)を含有していた。原料粉末は、実施例2における場合と同じプログラムを経させた。
異なるバインダーを、市場から入手可能なCSAセメント(組成については表6を参照)及び実施例1〜3からの3種のグレードのテルネサイト、並びにMicroAと混合した。表4は、テルネサイトの組成を、そして表5は、セメントとの混合比をそれぞれ示している。図1〜図4は、0.7のw/bで水と混合した際の混合物の熱流量及び累積熱流量を示している。表7は、実施例4によるセメントの鉱物学的特性(RietveldによるQXRD)及びセメント及びそれらから製造された、100%ペーストに標準化された硬化セメントペースト;w/c0.7の熱重量データ(水と化学的に結合)を示している。
