Admixtures

Accelerators

Description

Accelerators in concrete serve as admixtures to speed up the hardening process, enabling the concrete to achieve early strength faster. Although accelerators do not necessarily impact the time it takes concrete to set, they reduce this time in practice. A common accelerator is calcium chloride, which is particularly useful for hastening early st...

Transcript

An admixture is an additional substance added to the concrete during mixing to include a unique feature.

Admixtures used to accelerate the hardening of concrete are accelerators; these do not have to affect the setting time of the concrete.

During early hydration, an accelerating admixture should enhance the dissolution of the slow...
