Additives for concrete or concrete with fluidizing and superfluidifying effects. They significantly improve the workability of the dough, without varying the dose of water, or the water / cement ratio, achieving increases in the seat in the Abrams cone from five to twenty centimeters. The concrete maintains its cohesion without presenting exudation, segregation, or loss of its resistance.
These characteristics are very useful for the concreting of pieces of complicated geometry or with great concentration of reinforcements, as well as for pumping concrete and in prefabrication. They also allow a quick and economical start-up, since it is not necessary, in general, to vibrate the mass of the concrete, given its great fluidity.
