  • Additive for the preparation of ecological permeable concretes with high compression, bending and abrasion resistance, and production process
    Patent number: 6824605
    Abstract: An additive for elaboration of ecological permeable concretes. The additive containing from about 24.5% to 28.2% by weight of a mixture made of dispersing agents, from about 3.3% to 3.8% by weight of a humectant agent, from 0 to about 1% by weight of a nonionic surfactant, from 0 to about 3% by weight basis of a bactericidal agent, from about 3.3% to 3.8% by weight of hydroxypropylethyl or methylcellulose from 0 to about 0.3% by weight of an antifoaming agent and from about 55.8% to 64.2% by weight of a highly reactive non-crystalline calcinated silica aluminant.
