Abstract
A concrete product set by pouring a concrete slurry includes a concrete mixture, an aluminum-coated colloidal silica admixture, and optionally, at least one reinforcing fiber selected from the group of fibers. As the poured concrete slurry cures, the poured slurry hardens into a composite material product, and the concrete product defines capillary structures that at least in part fill with aluminum-coated silica and lime. Optional graphene oxide may be used in the concrete slurry, in which embodiment the surrounding aggregate and cement is embedded with graphene oxide flakes. A process for placing a jointless and/or fiberless slab made from the concrete product includes preparing a concrete slurry, pouring the concrete slurry onto substrate, and allowing the concrete slurry to cure.
Claims18
A method for producing a concrete product for industrial and commercial applications comprising:
- a) preparing a concrete slurry with a water to cement ratio of between about 0.400 to about 0.450, with fibers selected from the group consisting of steel fibers, macro synthetic fibers, and combinations thereof;
- b) preparing the concrete slurry with an additive selected from the group consisting of colloidal silica, graphene oxide, and combinations thereof;
- and
- c) pouring the concrete slurry to form the concrete product,
- wherein the colloidal silica is an amorphous nanometer-sized silica (SiO 2) in a particle size ranging from between about 3.0 nm to about 100.0 nm in aqueous solution and the colloidal silica aqueous solution is added to the concrete slurry during the preparation phase in ranges of between about 0.50% to about 1.50% by weight of cement.
A method for producing a concrete product for industrial and commercial applications comprising:
- a) preparing a concrete slurry with a water to cement ratio of between about 0.400 to about 0.450, with fibers selected from the group consisting of steel fibers, macro synthetic fibers, and combinations thereof;
- b) applying the concrete slurry to a substrate;
- c) allowing the concrete slurry to cure to form the concrete product;
- and
- d) preparing a spray solution comprising an additive selected from the group consisting of colloidal silica with particle sizes of between about 3.0 nm to about 50.0 nm in an aqueous solution, graphene oxide flakes with particle sizes of about 0.5 nm, and combinations thereof, and spray-applying the spray solution to the cured concrete product.
A method for producing a concrete slab on a substrate for industrial and commercial applications comprising:
- a) preparing a concrete slurry comprising a concrete mixture, a colloidal silica admixture, and a graphene oxide admixture;
- b) pouring the concrete slurry onto the substrate;
- and
- c) allowing the concrete slurry to cure,
- whereby capillary pores develop in the concrete as the concrete slab sets from the poured concrete slurry, silica and calcium hydroxide (Ca(OH)2) at least partially fill the capillary pores of the concrete, the silica and calcium hydroxide react to produce a gel structure of calcium silicate hydrate within the capillary pores, and the concrete is embedded with the graphene oxide and wherein the colloidal silica is an amorphous nanometer-sized silica (SiO 2) in a particle size ranging from between about 3.0 nm to about 100.0 nm in aqueous solution and the colloidal silica aqueous solution is added to the concrete slurry during the preparation phase in ranges of between about 0.50% to about 1.50% by weight of cement.

- b) preparing the concrete slurry with an additive selected from the group consisting of colloidal silica, graphene oxide, and combinations thereof;
- c) pouring the concrete slurry to form the concrete product;
- and
- d) spray-applying additional quantities of the additive to a surface of the concrete product after the concrete slurry has cured to a desired amount;
