流态混凝土(有的叫大流动度混凝土,也有叫自流密实混凝土)是一种新型的混凝土。它由混凝土掺入高效能减水剂而成,坍落度在18～20厘米,自由流淌距离在1.2米范围内,混凝土不出现离析现象。它在浇灌过程中,不需要对混凝土进行振捣或稍加振捣即可达到充填密实的效果。特性与应用流态混凝土既有干硬性混凝土的硬化性质,又有塑性混凝土操作性质。由于掺加了高效能减水剂具有较高的早期强度,一般七天强度
Fluid concrete (some called high fluidity concrete, also known as gravity-enhanced concrete) is a new type of concrete. It is made of concrete mixed with a high-performance water-reducing agent, with a slump of 18 to 20 centimeters and a free flow distance of 1.2 meters. The concrete does not show segregation. In the process of watering, it can achieve the effect of filling and compaction without vibrating concrete or slightly vibrating the concrete. Characteristics and Application The fluidized concrete has both the hardening properties of dry-hard concrete and the operational properties of plastic concrete. Due to the high early strength of high-efficiency water-reducing agent, generally seven days
