QUALITY CONTROL METHOD FOR CEMENT-BASED SOLIDIFYING MATERIAL
To provide a method capable for quickly and easily controlling a quality of a cement-based solidifying material.SOLUTION: In a quality control method for a cement-based solidifying material, a mixing ratio of materials contained in the cement-based solidifying material is estimated based on a chromaticity L value and b value of the cement-based solidifying material measured using a Hunter color difference meter. It is preferable to estimate a proportion of cement contained in the cement-based solidifying material based on a regression formula: C=c1+c2X+c3Y, where a proportion of cement contained in the cement-based solidifying material is C (mass%), the L value is X, and the b value is Y.SELECTED DRAWING: None
【課題】セメント系固化材の品質を迅速且つ簡易に管理し得る方法を提供すること。【解決手段】ハンター色差計を用いて測定したセメント系固化材の色度Ｌ値及びｂ値に基づき、該セメント系固化材に含まれる材料の混合割合を推定する、セメント系固化材の品質管理方法である。セメント系固化材に含まれるセメントの割合をＣ（質量％）とし、Ｌ値をＸとし、ｂ値をＹとしたとき、回帰式：Ｃ＝ｃ１＋ｃ２Ｘ＋ｃ３Ｙに基づきセメント系固化材に含まれるセメントの割合を推定することが好適である。【選択図】なし
