Cyclodextrin and concrete

With the increase of temperature, the retardation effect of hydroxycarboxylic acid and its salts is obviously reduced. In the hot weather environment, it can be used as a new type of high temperature retarder - The complex inhibited the hydration of tricalcium silicate and temporarily delayed the hydration process of cement, and had a very good effect on the inhibition of concrete slump loss. The main role of the use of cyclodextrin in concrete is as follows: For the hot weather in high temperature environment, concrete construction and mass concrete pouring molding on the condensation time (initial and final condensate) delay. The following are the same as the " Large volume of concrete doped with cyclodextrin can slow the release of hydration heat, is conducive to heat dissipation and reduce the temperature difference between concrete inside and outside, to avoid the occurrence of temperature cracks. The following are the same as the " Commercial concrete and fluidized concrete mixed with cyclodextrin can be adjusted to control the slump loss, is the concrete in the required period of time to maintain good mobility and pumpability. The following are the same as the " It can significantly improve the density of concrete to improve the durability of concrete, such as high-iron bridges and other key national projects.
