（２−１０）混合材含有量５０質量％の水硬性粉体の調製
クリンカー４７質量％、二水石膏３質量％、高炉水砕スラグ２５質量％、フライアッシュ２５質量％の粉砕原料を、粉砕助剤を添加せず、ボールミルでブレーン値３６００ｃｍ²／ｇまで粉砕して、混合材含有量５０質量％の水硬性粉体を調製した。 (2-10) Preparation of hydraulic powder with mixed material content of 50% by mass Grinding raw material of clinker 47% by mass, dihydrate gypsum 3% by mass, blast furnace granulated slag 25% by mass, fly ash 25% by mass Without adding an auxiliary agent, the powder was pulverized to a brane value of 3600 cm ² / g by a ball mill to prepare a hydraulic powder having a mixed material content of 50 mass%.

実施例３−１〜３−７及び比較例３−１〜３−８
混合材含有量５０質量％の水硬性粉体１００質量部に、表３で示した強度向上剤組成物を表４の量で用いて水硬性組成物を調製した。そして、水硬性組成物調製後、３日後及び２８日後の圧縮強度を測定した。結果を表４に示した。なお、表３で示した比較例Ｃ−１の配合のうち、糖類に関する組成は、国際公開第９７／３７９５２号の表１を参考に、国際公開第９７／３７９５２号の範囲内で、且つ本願の範囲外となるような組成を比較例Ｃ−１として定めた。さらに表３の他の実施例、比較例は、比較例Ｃ−１の配合比率を基本とし、（Ａ）成分とその他の成分を増減させたものである。 Examples 3-1 to 3-7 and comparative examples 3-1 to 3-8
A hydraulic composition was prepared by using the strength improver composition shown in Table 3 in the amount shown in Table 4 for 100 parts by mass of the hydraulic powder having a mixed material content of 50% by mass. And the compressive strength after 3 days and 28 days after hydraulic composition preparation was measured. The results are shown in Table 4 . In addition, among the composition of Comparative Example C-1 shown in Table 3, the composition relating to the saccharide is within the scope of International Publication No. 97/37952 with reference to Table 1 of International Publication No. 97/37952, and the present application A composition that falls outside this range was determined as Comparative Example C-1. Further, other examples and comparative examples in Table 3 are based on the blending ratio of Comparative Example C-1, and the component (A) and other components are increased or decreased.
