Abstract
A method of fabricating a concrete slab on ground system includes depositing wet geopolymer cement concrete on a ground substrate to generate a first slab. Wet Portland cement concrete is then deposited on the first slab to generate a second slab.
Claims20
A method of fabricating a concrete slab on ground system, comprising:
- by a set of transport vehicles including
- a first transport vehicle operable to transport materials selected from the group consisting of fly ash, ground granulated blast furnace slag, metakaolin, ground glass, and mixtures thereof,
- a second transport vehicle operable to transport liquid ingredients of a geopolymer cement concrete, and
- a third transport vehicle operable to transport sand and rocks, and
- by a concrete mixing vehicle operable to transport wet Portland cement concrete in the concrete mixing vehicle,
- maneuvering the set of transport vehicles to a site having a ground substrate;
- transferring a quantity of the materials and a quantity of the liquid ingredients to the third transport vehicle;
- mixing, in the third transport vehicle, the quantity of the materials, the quantity of the liquid ingredients, and the sand and rocks to generate a wet geopolymer cement concrete;
- depositing the wet geopolymer cement concrete on the ground substrate to generate a first slab;
- maneuvering the concrete mixing vehicle to the site;
- and
- depositing the wet Portland cement concrete on the first slab to generate a second slab.
