    • 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. The use of this additive ensures a more uniform distribution of gas pores in the concrete.
    • 用于生产加气混凝土,使用与减水,分散剂和/或流动性增强性质的有机添加剂的建议。 该添加剂是至少其中一个代表整个系列缩聚产物的基于萘或烷基萘磺酸,基于不饱和单或二羧酸衍生物和氧亚烷基二醇链烯基醚三聚氰胺 - 甲醛树脂以及它们的共聚物含磺酸基的。 这种添加剂,优选添加到非发泡,并且更具体的加气混凝土含0.01和10之间重量%的石灰,水硬性粘合剂,水泥优选和砂,用量的游离水基混合物混合都被认为是优选的。 用于产生加气混凝土所提出的方法的使用可以是显著更加节能,从而进行成本有效地,在不改变的典型性能是由多孔混凝土产品的不利影响。 使用该添加剂的引起混凝土气体孔的更均匀分布。
