  • Patent number: 10640423
    Abstract: Method to artificially agglomerate finely divided materials. A method to agglomerate finely divided material into aggregates, the aggregates being larger than the finely divided material, comprising the steps of (a) mixing finely divided material, binder and water in a mixer, (b) adding an agglomerating agent to the mix formed in step (a) and mixing constantly. Finely divided material is selected from the group consisting of cement, sand, clay, glass, slag, fly ash, stone powder, bypass dust, limestone, silica fume, crushed brick, brick powder and crushed stone or a combination thereof.

  • Patent number: 10259747
    Abstract: A concrete mix having sand, fine aggregates, binder, fibers, and various admixtures is provided. The mix has a consistency from S2 to SF3, a compressive strength in the range of 30-80 MPa and a ductility represented by fc, ffl, fR1 and fR3 values, wherein the concrete mix contains at least 390 Kg of binder, the concrete mix has a paste volume of 300-600 liters, the concrete mix contains at least two systems of fibers and a general admixture system that is composed of at least 2 sub-admixture systems.

  • Publication number: 20180162774
    Abstract: Method to produce aggregates from unsettled cementitious mixtures, comprising the steps of (a) adding at least one pelletizing agent to an unsettled cementitious mixture, (b) mixing constantly the mixture of step (a) in a mixer to produce pellets, (c) discharging the pellets obtained in step (b) and (d) drying the pellets formed in step (c). The pelletizing agent is selected from the group consisting of cellulose, chitosan, collagen, polyacrylamide and co-polymers of polyacrylamide and polyacrylics, polyamines, polyvinylalcohols, polysaccharides, lactic acid, methacrylic acid, methacrylate, hydroxyethyl, ethylene glycol, ethylene oxide, acrylic acid, inorganic flocculants and inorganic coagulants.
