Abstract

Ultra-retardation concrete is a kind of concrete, which can change the setting time over a long period of time by adjusting the dosage of retarder, without damaging the concrete performance, and its later strength is affected by the high dosages of retarder. At present, ultra-retardation concrete is mainly used in deep foundation pit support structures in high-rise buildings and subway construction processes, and ultra-large volume concrete with special requirements for concrete setting time, such as ultra-long diameter underwater pile foundation engineering. It has a wide range of application advantages in the construction of interlocking piles in subway stations and other areas. In this paper, we want discuss the preparation of ultra-retarding concrete through using super retarder.
