In your opinion, what role will the concrete additives play in the course of the heat-hardening chemical interactions in the years following the hardening of the concrete, inside the concrete, and how will they have a negative or positive effect on the durability of the concrete? During what chemical reaction will they reduce or increase the durability of concrete? Imagine we want to investigate this 5 years after concreting.
you are asking about which type of additive
if you can give me more details about the additive it will be helpful

Your question has been asked in general and it would be better to specify what kinds of additives you are considering and under what conditions the durability of concrete is going to be assessed, because durability of concrete can be defined as the ability of concrete to resist weathering action, chemical attack, and abrasion while maintaining its desired engineering properties.
Given the general nature of your question, let me provide a general response. Just about all chemical additives used in concrete provide very long term benefits (>10 yrs) to concrete durability. Whether the additive is a simple commonly used water reducing admixture or the more complex corrosion inhibitors and shrinkage reducing admixtures, they all influence both the short and long term properties of cementitious mixtures. Modern concrete technology calls for the use of a wide range of chemical additives to improve not only concrete durability, but its placeability and consolidation, environmental impact, and economy. The chemical admixture industry can be regarded as a research arm of the concrete construction industry.
The development of the solid strength of concrete only until the age of 28 days, after 28 days of development the strength is relatively non-existent
Dear Researcher,
As the majority of researchers said, you should specify which kind of addition you will use. therefore, you can search in the literature what researchers have found. Besides, to assess the durability of your concrete, several tests are available to foresee (calculate) the durability indicators.
