COMPOSITION OF AN ADDITIVE FOR MANUFACTURING HIGH-STRENGTH CONCRETE FOR PREFAB CONSTRUCTION, AS WELL AS FOR PERVIOUS CONCRETES AND THE RESULTING CONCRETES

摘要

The present invention relates to the construction industry in general, and specifically to additives incorporated into high-strength concretes for prefab construction, as well as for pervious concretes, improving their physical properties, characterized in that they include the following components: water, at least one dispersing agent, at least one bactericidal agent; at least one thermo-adherent mineral; at least one polymer-based hydrodispersing agent; calcium carbonate and silico-aluminate; an oxidizing silicon aluminum agent; at least one anti-scaling, anti-corrosive and dispersant; anti-scaling calcium and at least one hydraulic binder, or mixtures thereof, and where each cubic meter of the hydraulic high-strength concretes includes: 110 to 250 liters of water; 530 to 630 liters of sand; 700 to 750 liters of gravel; 300 kg of cement and 9.5 liters of the additive; and where each cubic meter of the pervious concretes includes: 70 to 130 liters of water; 1 to 1.4 m3 of aggregates; 100 to 330 kg of cement and 2.88% of the additive with respect to the weight of the cement.
