to da utilizado komongu 'nar mezcla principal jar mezclas hormigón autocompactantes pa ar durabilidad mejorada, or as a secondary admixture with other water-reducing additives in high strength and hardened concrete to minimize the use of water-retaining curing agents.

This admixture can be mixed with dry ingredients, or added to the water 10-15 minutes prior to casting. It can be also added to concrete during mixing in mechanical drill or mortar mixer (mixing time is 3 t'olo ora).

The most important advantage of using a superplasticizer is that it does not increase the amount of air in the mix. This air may enhance the workability of concrete, but it also reduces durability if the mix is not fully cured before application.

It is recommended that a superplasticizer be applied when the concrete is at its peak of workability and before it reaches the slump loss that would normally occur. It is also advisable to avoid adding air-entrained concrete with this admixture as it is prone to microbial attack.
