    摘要： The invention relates to an expanded concrete composed of binder-containing mixtures, preferably having binders composed of Portland cement as specified in DIN EN 197 or of mixtures of hydraulic, latent-hydraulic and/or pozzolanic binders, having binders, water with a fraction of 20-60% by mass based on the mass of the binder in the mixture, chemical gas-forming agent, preferably in the form of aluminum powder, at 0.05-0.25% by mass, based on the mass of the binder, for forming mostly air pores in the expanded concrete, wherein the gas-forming agent in the form of a powder forms a mixture of different particle sizes, concrete additives such as in particular microsilica and/or flyash with a fraction of 0.5-25% by mass, based on the mass of the binder, concrete admixtures of mostly liquefying character and at a fraction of 0.5-5% by mass, based on the mass of the binder, wherein the distribution of the air pores of different sizes in the matrix of the expanded concrete, depending on its consistency, makes possible a compressive strength up to 30 N/mm2 after curing, and the expanded concrete is air-curing at atmospheric pressure under normal ambient temperature. In addition, a method is proposed of producing such an expanded concrete, and also a test method of determining the fresh concrete properties of an expanded concrete according to the invention.

    摘要： Provided is a porous humidity-control tile including about 40% to about 95% by weight of diatomite, and one or more of ochre, red clay, kaolin, zeolite, illite, vermiculite, feldspar, pottery stone, and pyrophyllite. The porous humidity-control tile has about 10 vol % to 80 vol % of cellular spherical pores having a size corresponding to a size of hollow pore forming material that is removable by heat treatment. The porous humidity-control tile has a rate of moisture adsorption/desorption per unit weight in a range from about 20 g/kg to about 60 g/kg and a rate of moisture adsorption/adsorption per unit area in a range from about 150 g/m2 to about 450 g/m2. Therefore, the porous humidity-control tile can be light, and the amount of adsorption/desorption per unit weight of the porous humidity-control tile can be improved.

    摘要： A cured porous phenolic resin is provided that can be made by cross-linking a phenol-formaldehyde pre-polymer in the presence of a pore former, preferably ethylene glycol. The resin may be formed in situ by condensing a phenol with or without modifying agents and with cross-linking agent by pouring partially cross-linked resin into hot oil, in which case mesoporous resin beads are obtained. The resulting resin has mesopores observable in carbon derived from said resin by a pore structure of said derived carbon that comprises mesopores of diameter of 20-500 Å, as estimated by nitrogen adsorption porosimentry, the value for the differential of pore volume V with respect to the logarithm of pore radius R (dV/d log R) for the mesopores being greater than 0.2 for at least some values of pore size in the range 20-500 Å. Microporous beads of the resin may be carbonized into mesoporous carbon beads.
