    Abstract: The present invention provides pourable aqueous dispersion compositions of (a) one or more cellulose ethers and (b) one or more superplasticizers stably suspended in an aqueous dispersion of (c) one or more stabilizers in the form of a colloidal dispersion, further containing (d) one or more monovalent salts, such as an alkali metal salt. The minimum total amount of the cellulose ether, as solids in the pourable aqueous dispersion is 8 wt.% or, preferably, 12 wt.% or, preferably, 14 wt.% and the solids weight ratio of total cellulose ether to salt is close to 1:1, ranging, for example, from 0.7:1 to 1.4:1. Further, the amounts of the (a) one or more cellulose ethers and the (b) one or more superplasticizers enable the provision of pourable aqueous dispersion compositions effective for use in cement applications by simple dilution with water.

    Abstract: The invention relates to processes for making improved ultra-high performance microfiber concrete and articles made from the same. The invention includes blending first dry constituents of fine aggregate, steel fiber, and cement to yield a first homogenous dry mix, optionally adding carbon nanotubes and/or silicon carbide microinclusions, followed by blending with second dry constituents of silica fume, silica flour, and cenospheres to obtain a second homogenous dry mix, followed by adding water only, with further blending, and finally adding a superplasticizer admix and a water-reducing admix to obtain ultra high performance microfiber concrete. The invention also relates to voltage heating for curing and for creating heated UHPC articles.

    Abstract: A concrete product set by pouring a concrete slurry includes (a) a concrete mixture; (b) a graphene admixture (102); and (c) at least one reinforcing fiber selected from the group of fibers (24). As the poured concrete slurry cures, the poured slurry hardens into a composite material product, and the composite material is embedded with graphene. In another exemplary embodiment, the present invention is directed to a process for preparing a concrete product (800). The process comprises the steps of (a) preparing a concrete slurry with integral graphene (402); (b) pouring the concrete slurry (404); (c) allowing the concrete slurry to cure (406); and (d) optionally spray-applying graphene (408) and/or optional colloidal silica (402) as a curing technique. In another exemplary embodiment, the present invention is directed to the product itself; namely, a concrete product with fibers and embedded graphene.

    Abstract: An installation for cooling concrete which contains a predetermined quantity of water comprises an airtight casing (20), in which there are defined a chamber (1) which is intended to contain a desired quantity of concrete, an inlet opening (2) for the concrete into the chamber (1) and a pipe (3) which communicates with the chamber (1) and which extends from the chamber (1) to an outlet opening (5) for the concrete which is defined in the casing (20) at one end of the pipe (3) at the side opposite the chamber (1). The pipe (3) is configured to convey the concrete from the chamber (1) towards the outlet opening (5). The installation further comprises a vacuum pump (10) which is connected to the chamber (1) in order to adjust a degree of reduced pressure therein so as to bring about at least a partial evaporation of the water from the concrete, and a condenser (12) which is arranged inside the chamber (1) in order to condense the evaporated water. The condenser (12) is configured in such a manner that the condensed water flows into the concrete inside the chamber (1) and/or pipe (3).

    Abstract: The present invention relates to a method and system to produce a concrete material having optimized strength and particle packing properties. The method and system includes a micro characterization step of a plurality of starting cementitious materials and at least one starting pozzolanic material to get respectively at least one cementitious material having uniform strength and at least one pozzolanic material having uniform blain fineness. Then grinding the said at least one cementitious material having uniform strength and the said at least one pozzolanic material having uniform blain fineness to get at least one cementitious material having a required Blaine fineness and at least one pozzolanic material having a required Blaine fineness. Finally preparing the said concrete material by mixing the said micro characterized cementitious materials and/or pozzolanic materials with at least one aggregate material, at least one additive material or a mixture thereof.
