    Abstract: A porous refractory body, primarily a porous plug for the refractory lining of a vessel containing molten metal through which plug gas can be blown into the metal. This body has a cold crushing strength of not less than 200 kg/cm2 and consists of a coarse-grained refractory material with a minimum quantity of a suitable binding agent, and has permeable pores of a cross section not less than 0.05 mm and a gas permeability of at least 100, and preferably more than 500 nanoperm. The hot bending strength or modulus of rupture of the body at 1,400* C is from 20 - 60 kg/cm2. The refractory material is mixed with the binding agent, and the mixture is compressed with a pressure of at least 300 kg/cm2 before firing to bring substantially all of the grains into contact with adjacent grains.

    Abstract: PURPOSE: A concrete brick is provided to remarkably decrease the weight of a brick by manufacturing a brick using ingot which is made by melting the waste styrofoam, and to promote the thermal insulating effectiveness. CONSTITUTION: The concrete brick is manufactured by: mixing usual aggregate with the waste styrofoam reproduced aggregate which having its particle sized to be modulated according to the standard of aggregate about concrete bricks by pulverizing and processing the waster styrofoam ingot using a crusher; mixing cement to have 1:7 of ratio of the waste styrofoam to the reproduced aggregate; pressurizing using a vibrating press. Therefore, the concrete brick using the waste styrofoam reproduced aggregate meets the standard of KS F 4004, and particularly having 1120-2100 kg/m¬3 of unit volume weight, 93-320 kg/cm¬2 of compressing strength; 6.2-11.7 % of absorption rate, and 0.28-1.35 kcal/mh°C of heat conduction rate.

    Abstract: The present invention provides cementitious tile adhesives comprising ordinary Portland cement, sand or another inorganic filler, and from 0.12 to 0.6 wt.% of total solids of one or more polyether group containing crosslinked cellulose ethers. The present invention also provides methods of making the polyether group containing crosslinked cellulose ethers comprising crosslinking a cellulose ether at 90 °C or less, in an inert atmosphere, e.g. nitrogen, in the presence of a polyether group containing crosslinking agent and in the presence of alkali; the process may comprise part of a stepwise addition process of making of a cellulose ether itself in which the crosslinking of the cellulose ethers precedes at least one addition of alkyl halide or alkylene oxide to form, respectively, alkyl or hydroxyalkyl groups on the cellulose.

    Abstract: The invention relates to an agglomerate containing at least one of the following water-soluble or water-dispersible materials as a bonding base polymer: carboxylized and/or alkoxylized starch, cellulose ether and fully synthetic vinyl polymers and/or polyacrylates. The agglomerate is characterized in that it contains a blasting agent which produces a high swelling pressure, but, advantageously, does not gel. The agglomerate can have a regular geometric form or not. Its weight should be between 0.5 and 500g. The agglomerate is used in particular in the production of lump-free paste.
