Admixture, additive or agent
Concrete is a mixture of three ingredients: aggregates, cement and water. Adding concrete admixtures will result in better quality, better performance and it makes the construction last longer.
Admixtures for concrete to be added in low doses (less than 5% of total volume). This should be added at the time of mixing the concrete. They accelerate the hydration of the concrete. The accelerators are of two types, setting accelerator and hardening accelerator. They facilitate the concrete layers by making it more manageable. The water-reducing plasticizers give it better resistance.
