The effect of loading rate on concrete splitting tensile strength for different lateral stresses is studied.

系统地探讨了有侧应力作用时，混凝土在不同加载速率下的劈拉强度规律。

Mixed concrete splitting tensile strength enhanced obviously, and have excellent strength restore performance.

混杂混凝土劈裂抗拉强度明显增强，并具有极好的强度恢复性能。

The test results indicated that the bond splitting tensile strength of modified fly ash mortar was best in joint materials of sorts.

试验结果表明，各种接缝面材料中，粉煤灰改性砂浆的劈裂抗拉强度最大，效果最好。

The result demonstrates that the roughness of old concrete and adhesive agent have important influence on bond splitting tensile strength.

结果表明，老混凝土表面粗糙度、界面剂对粘结强度有较大影响。

Expansive cement paste and joint concrete are next. And the bond splitting tensile strength of joint surface without bond material is least.

其次是水泥膨浆和接缝混凝土，接缝面不铺筑任何接缝面材料的试块，劈裂抗拉强度最小。
