<p>The invention relates to an additive for producing permeable concrete with improved properties, and to a method for the preparation of said additive, comprising, in relation to 100% of the composition: between 33.70 and 54.90% of water; between 0.30 and 0.50% of antifoaming agent; between 0.30 and 0.40% of bactericide; between 0.30 and 0.50% of polyglycol; between 7.20 and 24.00% of a combination of emulsifiers; between 15.50 and 17.00% of wetting agent; between 0.8 and 22.90% of dispersing agent; and between 0.70 and 1.00% of biopolymer. The additive for producing permeable concrete can be added to any type of stony aggregate and/or cement, improving the required mechanical properties of the product in each of the previous steps, during and following the hardening.</p> |
