Cement additives - ScienceDirect
Gelling agents can be added to the cement composition. The gelling additive migrates from the cement composition into the surrounding subterranean zone and forms a barrier as it forms a crosslinked gel there. This gel inhibits the gas migration into the cement. 10.1.
What are Concrete Additives? Why do we use them? Big D
The additives are added to a water-cement mixture to increase the life of the concrete control setting and hardening and fix the general concrete behavior. They can be powdered or liquid additives. The additives can be added at the manufacturing point or at the job site.

Cementing Additives Energy wells are designed to be a safe conduit for the recovery of oil gas heavy oil hydrates and even steam. The environments from which energy is extracted can be harsh and cement systems play a key role in maintaining the integrity of the well.
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.
Seven Must-Use Concrete Admixtures Additives
Admixtures are added to concrete batch immediately before or during mixing concrete. Concrete admixtures can improve concrete quality manageability acceleration or retardation of setting time among other properties that could be altered to get specific results.
