ADMIXTURE ADDITION AMOUNT DETERMINATION METHOD, ADMIXTURE ADDITION AMOUNT DETERMINATION METHOD, AND PROPRIETY DETERMINATION METHOD OF COMPACTION COMPLETION TIME
To quickly determine the optimum value of a parameter which affects a compaction propriety of a mixture containing a cement-based solidification material in which an admixture is blended.SOLUTION: An admixture addition amount determination method determines excess or deficiency of an addition amount of an admixture blended in a mixture containing a cement-based solidification material which is manufactured by mixing an aggregate, a cement-based solidification material and water and which is compacted before a lapse of a predetermined compaction completion time after manufactured. The admixture addition amount determination method includes the steps of: measuring a temperature of a sample 20 in which the admixture is blended and determining a development of a state change point of the sample 20 based on the measured temperature; and comparing a development time until determining that the state change point develops with the compaction completion time and determining excess or deficiency of the addition amount of the admixture blended in the sample 20.SELECTED DRAWING: Figure 5
【課題】混和剤が配合されたセメント系固化材含有混練物の締固め特性に影響を及ぼすパラメータの最適値を迅速に決定する。【解決手段】骨材とセメント系固化材と水とを混合することにより製造され、製造後、所定の締固め完了時間が経過するまでに締固めが行われるセメント系固化材含有混練物に配合される混和剤の添加量の過不足を判定する混和剤添加量判定方法は、混和剤が配合された供試体２０の温度を測定し、測定された温度に基づいて供試体２０の状態変化点の発現を判定する工程と、状態変化点が発現したと判定されるまでの発現時間と締固め完了時間とを比較して、供試体２０に配合された混和剤の添加量の過不足を判定する工程と、を有する。【選択図】図５
