Abstract: A layer of air-placed concrete or a ready-mixed concrete is produced by using, as mixing water, an aqueous suspension of a synthetically produced silica, for example a precipitated silica.

Abstract: Pressed objects (slugs) of pyrogenically produced oxides such as SiO2, Al2O3 and TiO2 are produced using a silica sol and water. As molding assistants thereby there is employed a polyhydric alcohol, e.g. glycerine or sorbitol. The water can be added adsorbed on a pyrogenically produced hydrophobized silica. The pressed object obtained can be used inter alia as catalyst carrier.

Abstract: Concrete and mortar receive hydrophobic properties if, to the cement/sand mixture on which they are based, a mixture of zeolite and silicone oil is added in proportions of 1 to 20 % by weight and distributed homogeneously. The mixture of zeolite and silicone oil may consist of 20 to 60 % by weight of silicone oil and 40 to 80 % by weight of zeolite.

Abstract: The method continuously meters powdery material using compressed gas, the supply of the latter to a double or multiple pipe via a branch pipe being alternately interrupted and the branch pipe filled with the material. The latter is then further transported by the gas. There can be a stop valve for the gas in each branch pipe, followed by a non-return valve. The stop valves are connected to a silo for the material and a vent pipe.

Abstract: Powders having a relatively low powder density can be emptied from transportation containers only with dust formation on an undesired large scale. The device for emptying containers filled with powders of the invention comprises a vacuum pipe, a fluidization device disposed thereon adjacent the open end of said pipe. This fluidization device may have the shape of a double cone shell disposed concentrically around the pipe or of a hollow sphere disposed concentrically around the pipe. The fluidizing air can be passed into the powder through boreholes disposed in the direction of the opening of the pipe. In order to prevent the vacuum pipe from becoming attached to the container wall by suction, the opening of the vacuum pipe has castellated rims.

Abstract: Pressed pieces of pyrogenically produced titanium dioxide are produced using organic or inorganic compounds having an acid reaction. Since the addition of binder aids such as silica sol, kaolin and the like is avoided, pressed pieces having a titanium dioxide content of up to 99% by weight are obtained with an accessible pore volume of 45-55% of the volume of the pressed piece and a hardness of at least 16 kp, the pressed pieces being suitable for use as catalyst supports.
