    摘要: Rubber-crumb-reinforced cement-concrete structures (such as mortar (20), cement board (30), concrete masonry units (40), and concrete pipe (50)) provide resistance to cracking, increase resistance to acid rain, lower weight, improve shock wave absorption, lower heat conductivity and improve the acoustical environment. The structures preferably are made of concrete having a predetermined proportion (from about 1 to about 30 parts by weight per 100 parts by weight of cement) of recycled scrap rubber crumbs which are preferably unidirectionally aligned in the cross section of the structures.

    摘要: A ceramic hot-gas candle filter having a porous support of filament-wound oxide ceramic yarn at least partially surrounded by a porous refractory oxide ceramic matrix, and a membrane layer on at least one surface thereof. The membrane layer may be on the outer surface, the inner surface, or both the outer and inner surface of the porous support. The membrane layer may be formed of an ordered arrangement of circularly wound, continuous filament oxide ceramic yarn (b), a ceramic filler material (d) which is less permeable than the filament-wound support structure, or some combination of continuous filament and filler material. A particularly effective membrane layer comprises circularly wound filament with gaps intentionally placed between adjacent windings, and a filler material comprising ceramic particulates uniformly distributed throughout the gap region (c). The filter can withstand thermal cycling during backpulse cleaning and is resistant to chemical degradation at high temperatures.

    摘要: A sintered ceramic that exhibits an average linear coefficient of thermal expansion (25-800 DEG C) below about 5.0x10 DEG C , a total porosity between the range of 20% to about 30%. Furthermore, the sintered ceramic article exhibits a pore size distribution such that at least about 86% of pores are of a pore size of less than about 2 mu m. Lastly, the ceramic article exhibits an interconnected pore structure with the pores exhibiting a generally elongated shape, i.e., the pores are predominately oriented with their long axis in the plane of the webs. This invention also relates to a method for producing a sintered cordierite ceramic article involving first compounding and plasticizing a cordierite-forming inorganic powder batch comprising a platy talc having median particle of size less than about 2 mu m, and preferably a talc morphology index greater than about 0.75. The batch further comprises at least 4% by weight of the inorganic powder batch mixture of a dispersible A12O3-forming source having a specific surface area in excess of 50m /g and one or more of the components of kaolin, calcined kaolin, silica, and corundum, each having a median particle sizes less than 5 mu m. The plasticized powder batch thus provided is next formed into a green honeycomb by extrusion through a honeycomb extrusion die and the green honeycomb is fired to a temperature and for a time sufficient to convert the green honeycomb into a crystallized cordierite ceramic article having the aforementioned properties.
