Effects of high-frequency vibration on air void parameters of air-entrained concrete with four different types of air entraining agents (AEA) were studied.

研究了高频振捣对不同品种引气混凝土气泡参数的影响。

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。

The testing of air void parameters could been influenced directly by regarding stone powder as cementitious materials.

石粉是否作为浆体材料对于碾压混凝土的气泡参数测定有直接影响。

The dynamical control systems are also used in other control index of construction quality such as compaction degree, air void ect…

而对于施工质量的其他控制指标如压实度、空隙率等都同样可以进行动态控制。

Pavement Quality Indicator (PQI), a nondestructive monitor device, is introduced which canobtain a great deal of air void data of asphalt pavement fast.

沥青路面质量指示仪（PQI）是一种无损检测设备，可以快速、大量地获得路面空隙率数据。
