void factor

The main factor that influences the performance of the pervious asphalt mixture was investigated by performance test of mixture with different air void.

同时对四种不同空隙率和不同种类沥青的透水性沥青混合料进行性能测试及分析，提出了影响透水性沥青混合料性能的关键因素。

A multiplying factor on void growth was determined using smooth tensile specimen tests and pre-cracked side-grooved three-point bend bar tests.

由光滑拉伸试样和预制裂纹侧槽三点弯曲试样试验所确定的空穴增长系数，可能适宜较宽的试样拘束变化范围。

Contrarily , the air void spacing factor becomes smaller . 4.

相反, 气泡间距系数有所减小.

Air-void spacing factor of approximately 200 μ m is useful to protect concrete from freeze-thaw damage.

当引气混凝土的气泡间距系数小于200μm时，混凝土具有较高的抗冻性。

ABSTRACT: Being a parameter of concrete antifreeze evaluation, air void spacing factor had got much more attention.

作为评价混凝土抗冻性的参数之一，混凝土气泡间距系数越来越受到重视。
