Cement Additive an overview ScienceDirect Topics

Asphalt cement additives have been used to improve asphalt pavement performance as well as to reduce asphalt pavement distresses such as moisture damage, permanent deformation, and thermal fatigue cracking. The performance of modified asphalt pavement is expected to be more stable at warmer temperatures and more flexible at colder temperatures.

Accelerating admixtures are especially useful for modifying the properties of concrete in cold weather. Superplasticizers,also known as plasticizers or high-range water reducers (HRWR), reduce water content by 12 to 30 percent and can be added to concrete with a low-to-normal slump and water-cement ratio to make high-slump flowing concrete.
