Abstract

La presente invención se relaciona con un proceso para modificar las características de consistencia o derrumbamiento de un concreto o argamasa mediante la adición, a diferentes tiempos, de un poli(óxido de alquileno) hidrosoluble y un condensado de sulfonato de ß-naftaleno-formaldehído, un plastificante o superplastificante que se selecciona del grupo que consiste de lignosulfonatos, condensados de sulfonato de melamina-formaldehído, carboxilatos y copolímeros seleccionados de estireno-anhídrido maleico. El poli(óxido de alquileno) preferiblemente es reemplazado de manera parcial por una (hidro)alquilcelulosa. El proceso se utiliza con ventajas en la aplicación de 'shotcrete'.
