[摘要] 通過試驗(yàn)研究分析了齡期對(duì)砂漿強(qiáng)度的影響，并將回彈法、砂漿片剪切法試驗(yàn)檢測(cè)所得的砂漿強(qiáng)度試驗(yàn)實(shí)測(cè)值與標(biāo)準(zhǔn)試驗(yàn)值進(jìn)行比較，得出了回彈法、砂漿片剪切法之問的關(guān)系和與標(biāo)準(zhǔn)試驗(yàn)值之問的差異。采用最小二乘法原理以5種函數(shù)形式分別對(duì)不同的測(cè)試方法所得的試驗(yàn)測(cè)試數(shù)據(jù)進(jìn)行了回歸計(jì)算，分別給出天津市各檢測(cè)方法的砂漿測(cè)強(qiáng)曲線和測(cè)強(qiáng)計(jì)算公式，并進(jìn)行了誤差分析。

Abstract: The impact of age on mortar strength was mainly analyzed. With the standard value as the datum, the actual values obtained by rebound method and shear method were compared with standard values. The relationship between two methods and the difference from standard value were gained. Using the principle of least squares method, five kinds of functions were adopted to regression analysis test value. Finally detecting strength curves of Tianjin and formula of calculating strength are obtained.
Keywords: curing age; rebound method; shear method of mortar flake; mortar strength; compressive strength; detecting strength curve
