PERMEABLE CONCRETE ON A CEMENT BINDER WITH THE ADDITION OF HIGHLY DISPERSED CALCIUM SILICATES Russian patent published in 2021 - IPC C04B28/04 E01C7/30 

FIELD: construction.

SUBSTANCE: invention relates to the construction of roads, parking lots and sidewalks; it can be used to remove moisture from the surface of the roadway of bridge structures. Permeable concrete, in which crushed stone of 5-10 mm or 10-20 mm fractions is used as a large filler, Portland cement or slag-Portland cement is used as a binder, including the addition of highly dispersed calcium silicates based on cement production waste, has the following ratio of components: 84.9-91.8 wt.% of crushed stone, 5.46-10.58 wt.% cement, 2.46-4.06 wt.% water, 0.27-0.5 wt.% additives of highly dispersed calcium silicates based on Portland cement production waste - cement dust, 0.01-0.02 wt.% of water-reducing additive – “HIDETAL-GP-9” alpha “A”.

EFFECT: produced permeable concrete on a cement binder with the addition of highly dispersed calcium silicates.
