    摘要： A cement-based composition, useful as a coating material for corrosion-resistant protection on steel and iron surfaces, comprises:

    (a) 100 parts by weight of a hydraulic cement;
    (b) from 10 to 36 parts by weight of an aqueous emulsion of a polymer capable of exhibiting good adhesion to the surface of steel and withstanding the attack of chloride ions, the amount of the emulsion being calculated as the content of the polymer therein; and
    (c) from 3 to 30 parts by weight of an aqueous emulsion of a hydrocarbon solvent containing from 0.5 to 2.0% by weight of a saccharide compound and a combination of from 0.8 to 2.0% by weight of a first non-ionic surface active agent soluble in the hydrocarbon solvent having an HLB value in the range from 10 to 14.5, from 0.8 to 2.0% by weight of a second non-ionic surface active agent soluble in water having an HLB value in the range from 15 to 18 and from 0.3 to 1.0% by weight of a cationic surface active agent soluble in water, the amount of the emulsion being calculated as the content of the hydrocarbon solvent and the amounts of the saccharide compound and the surface active agents each being based on the amount of the hydrocarbon solvent contained in the emulsion. By virtue of the unique formulation, the composition has a greatly extended pot-life suitable for dip-coating steel rods and pipes and the like.

    摘要： The present invention provides a wet press process and admixture components for making concrete slabs (flags) (16), curb (kerb) units, panels, boards, and other flat shapes, whereby colloidal silica and at least one alkanolamine and optional rheology control components are employed to provide an ideal combination of pressing time, green strength, surface definition, stack-ability, final concrete strength, and permeability. Stack-ability can be expressed in terms of minimum deflection or non-eccentricity of the units while standing on thickness edges at distances apart less than width or standing height. A wet press process typically involves introducing a highly fluid concrete mix into a mold (10,12), applying hydraulic pressure to consolidate the concrete (e.g., 1000-3000 PSI) and to extract excess water, removing the pressed concrete (16) while in a green state from the mold (10,12), and then standing the slab (16) units immediately upon removal from the mold (10,12) while in a green state, on an edge adjacent to but spaced apart from other edge-standing units. In further embodiments, rounded aggregates such as naturally occurring sand and/or gravel obtained from local sources can be incorporated into the concrete slabs without defeating (vertical) stack-ability in the green state.
