1·The invention discloses a testing device of the volume compression coefficient of freshly mixed concrete under a side-limit condition and a testing method thereof.

本发明公开了一种侧限条件下新拌混凝土体积压缩系数的测试装置及其测试方法。

2·The air content of freshly mixed concrete is determined by measuring the reduction in the volume of the concrete caused by the application of a specified pressure to the concrete.

通过对混凝土施加特定的压力，测定混凝土体积的减少量，以此确定混凝土拌合物中的空气含量。
