Abstract (en)
[origin: WO2007009732A2] In order to produce porous concrete, the use of an organic additive with water-reducing, dispersing and/or flowability-increasing properties is provided. This additive is at least one representative of the series of polycondensation products based on naphthalinsulfonic acids or alkylnaphthalinsulfonic acids, melamine-formaldehyde resins containing sulfonic acid groups, and copolymers based on unsaturated mono- or dicarboxylic acid derivatives and on oxyalkylene glycol-alkenyl ethers. This additive is preferably admixed to a non-foamed and, in particular, mixing water-free porous concrete base mix containing lime, a hydraulic binder, preferably cement and sand, whereby quantities between 0.01 and 10 % by weight are considered as preferred quantities. By using the additive in the aforementioned manner, the method for producing porous concrete can be carried out using distinctly less energy and thus more cost-effectively without negatively influencing the typical properties of porous concrete products.
