Application of cyclodextrin as a concrete slow release agent

- Aug 10, 2018 -

As the temperature rises, the retardation effect of hydroxycarboxylic acid and its salts is significantly reduced. In the hot weather, the new high-temperature retarder-beta-cyclodextrin and the calcium hydroxide in the cement are unstable. The complex inhibits the hydration of the tricalcium silicate and temporarily delays the hydration process of the cement, and has a very good effect on suppressing the slump loss of the concrete.
