膨胀混凝土在加固钻孔灌注桩中的应用

Application of expansive concrete in reinforced cast-in-situ bored pile

膨胀混凝土应用于钻孔灌注桩中,能够提高桩土效应、桩的承载力和混凝土强度,节约水泥用量。通过一工程实例证明,采用膨胀混凝土是解决钻孔灌注桩缺陷问题的一种有效途径。

The application of expansive concrete in bored pile, improving pile foundation’s effect,pile bearing capacity and concrete strength, saving cement dosage. By the engineering example, it is an effective way to use expansive concrete to solve the defects of bored pile.
