Liquid suspensions of particles in non-aqueous solvents are extremely stable over long periods of time with minimum separation of the solvent and no hard packing of the dispersed particles. The suspensions enable a user to rapidly add the suspension to water and to mix at low speeds without generating fugitive dust in the process. In addition, a liquid dispersion can provide an easy to use liquid containing higher concentrations of the active dispersed phase than can be accomplished by simply preparing an aqueous solution of the dispersed phase. Alternatively, highly water-soluble particles may also be suspended which have poor storage, freeze/thaw, or heat/cool stability. In some cases, liquid dispersions can yield controlled release of the dispersed phase because the dispersed phase is not in aqueous solution. The suspensions are environmentally safe and biodegradable and may be used in environmentally sensitive applications, such as for oil well treating fluids for offshore areas. The suspensions exhibit minimal oil or grease upon dilution and contain no surfactants that which can sometimes add to the oil and grease determination. The suspensions and the fluids produced by diluting the fluids to a working concentration of dispersed phase exhibit low toxicity to marine organisms and to humans. The suspension can be manufactured from ingredients suitable for use in personal care applications, such as cosmetics, shampoos and the like; from ingredients suitable for use in indirect contact with food; and from ingredients that are exempt from regulations as adjuvants for agricultural pesticides. |

The invention comprises a composition comprising a natural pozzolan selected from hyaloclastite, sideromelane or tachylite, wherein the natural pozzolan has a volume-based mean particle size of less than or equal to 40 μm. The invention also comprises a cementitious material comprising a hydraulic cement and a natural pozzolan selected from hyaloclastite, sideromelane, tachylite or combination or mixtures thereof, wherein the natural pozzolan has a volume-based mean particle size of less than or equal to approximately 40 μm. The invention further comprises a cementitious-based material comprising aggregate, a cementitious material comprising a hydraulic cement and a natural pozzolan selected from hyaloclastite, sideromelane, tachylite or combination or mixtures thereof, wherein the natural pozzolan has a volume-based mean particle size of less than or equal to approximately 40 μm and water sufficient to hydrate the cementitious material. A method of using the composition of the present invention is also disclosed. |

This invention relates to the conveyance of cement under water to form concrete. The method claimed utilizes, inter alia, a positive displacement pump and feed pipe to convey unreacted cement, suspended in an environmentally safe and non-reactive liquid vehicle or carrier (polyethyleneglycol, for example), to an underwater site comprised of a hydrated aggregate mass (usually sand), permitting said carrier to diffuse from said suspension into surrounding water and further permitting said cement to react with water in the aggregate thereby causing the cement, water and aggregate mixture to form concrete. |
