What is the purpose of adding retarder and water reducing agent to pumped concrete?
1. Retarder: Pumped concrete mostly uses commercial concrete, which requires small slump loss. Especially for large-volume concrete or concrete constructed at high temperatures in summer, retarder mus…
Are concrete retarder and early strength agent mutually exclusive? Why should they be used?
Concrete retarder delays the initial setting time of concrete, that is, it inhibits the hydration rate of cement. Early strength additives increase the hydration rate and facilitate the early improvem…
Why are concrete retarder and early strength agent suitable for construction in high temperature and low temperature environments respectively?
Retarder for concrete is mainly used at high temperatures, because the concrete is made by pouring and smoothing, which requires a certain amount of time, and because of the high temperature environme…
