Given we have had a pretty chilly start to winter, we wanted to highlight the importance of managing your concrete batching through the various seasonal changes in order to get the best result.
The best way to achieve a quality finish on a cold or hot day is through admixtures. Accelerators when it is cold and Retarders in the hot weather, this can be dependent on a number of other factors like concrete batching strength or high winds.
Accelerating Admixture – an admixture that causes an increase in the rate of hydration of the hydraulic cement and thus shortens the time of setting, increases the rate of strength development, or both.
Retardant Admixture– Retarding admixtures have little or no effect other than to delay the setting of the cement. They do not plasticise significantly and have no effect on the water demand or other properties of the concrete. Retarding plasticising admixtures not only delay the setting of the cement but are also efficient plasticising water-reducers. Most commercially available retarders are of this type. Retarding plasticisers are used to give workability retention to the concrete, delay the setting time and increase initial workability
