| Accelerators |
Accelerators:During the concrete work If the temperature
fall into freezing point in cold days. That time the concrete can not set in time and can't get complete strength .So we use accelerators
to enhance heat in concrete for good setting. Often, this type of situations create on very cold areas. For this purpose we can use Calcium chloride, Calcium Chloride, Calcium nitrate and Sodium chloride.
Retarders:When we have to do concrete work If the temperature of environment is very hot. So before concrete setting the water of concrete be decrease as result concrete lose his strength and durability. Therefore, we use many type of retarders to maintain the setting time of concrete water and we get good strength. This type of situations create on hot areas. Some retarders are given under. Sugar and Carbohydrate.
