    Abstract: PROBLEM TO BE SOLVED: To obtain a concrete with which concrete member or buildings can be effectively protected from corrosion by adding an emulsion containing a hydrolyzable org. silicon compd. to a concrete mixture comprising an inorg. component, a small amt. of org. component and water. SOLUTION: In the production of a concrete, an org. silicon compd. expressed by the formula, and if necessary, aq. emulsion containing its condensate are added to a water-contg. mixture comprising an ironing. component usually used, and if necessary, a small amt. of org. component in the mixing process of the concrete or after mixing. In the formula, R is a1-3C alkyl; R is a1-20C alkyl or phenyl: (a) is 0 or 1; (b) is 1 or 2;(c) is 1 to 18; X is H, Cl, Br, I, NH2 , SCN, CN, N3 an NHR, an N(R)2 , an N(R)3 , an aryl, Sx or absent; R is same as R ; (x) is 1 to 6. The amt. of the org. compd. or the emulsion added is 0.1 to 10 wt.% of the cement. The mixture is hardened to obtain a concrete which can be made hydrophobic in a block state.

    Abstract: Homogeneously waterproofed concrete is produced by adding an aqueous emulsion containing a hydrolysable alkoxysilane compound and optionally condensation products thereof to the fresh concrete mix containing water, inorganic and possibly organic components and then allowing the mix to harden. A process for the production of bulk-waterproofed concrete, in which a water-containing mixture of known inorganic components and possibly small amounts of organic components is treated during (or possibly after) its production with an aqueous emulsion containing an organo-silicon compound of formula (I) and optionally condensation products thereof, and then allowed to harden. R, R1 = optionally branched 1-3C alkyl; R3 = 1-20C (preferably 1-10C) alkyl or phenyl; a = 0 or 1; b = 1 or 2; c = 1-18; X = H, Cl, Br, I, NH2, SCN, CN, N3, NHR, N(R)2, N(R)3 or aryl (especially phenyl) if b = 1, or alkenyl (especially 1-6C alkenyl) if b = 2, or Sx (with x = 1-6) if b = 2 and c = 1-6, or any group if b = 2 and c = 1-12 (preferably 1-6) . An Independent claim is also included for concrete mixtures containing known inorganic and possibly organic components plus an aqueous emulsion as above.
