Admixtures are chemicals added to concrete mixes either during the mixing phase or at the job site to achieve desired effects. They are typically added only in small quantities (≤12% of the cement mass). Following is a brief description of some of the more common admixtures and the effects they yield. 1. Plasticizers: These admixtures are often called "workability aids" or "water ...

Benefits of airentraining admixture: Increases workability of fresh concrete. Increased durability; Better resistance to freezing thaw cycles, deicers, salts, sulfates, and alkalisilica reactivity. Difficulties: Decreases strength. The effect can be reduced in moderate strength concrete by lowering water cement ratio and increasing cement ...

 · The additives used in this investigation were calcium and magnesium oxides and silies, nickel oxide, sodium hydroxide, sodium bicarbonate and strontium chloride. The experimental results showed that both the carbonation reactions and the compressive strength of drycast concrete mixtures were improved when using chemical additives. Experimental investigations for optimisation were .

Chemical Additives have a very important role to play to achieve more sustainable construction materials.
