摘要： A process is described for the formation of shaped hydrated calcium silicate products. The process comprises reacting an aqueous slurry containing a source of calcium hydroxide, perlite as a source of silica, and a soluble calcium salt in the presence of high pressure saturated steam, then adding cooling water followed by subsequent venting of the reactor vessel to ambient pressure. Reinforcing fibers may then be added after which the desired shapes are molded and dried.

摘要： Processes for the production of a hardenable mass having low permeability characteristics are disclosed, as well as the compositions produced thereby. The process includes providing a slurry produced from the scrubbing of sulfur oxide-containing gases with alkaline earth metal compounds, the slurry comprising an aqueous suspension of alkaline earth metal sulfites, mixing the slurry with a pozzolanically active waste material such as fly ash and an alkaline earth metal in the form of an alkaline earth metal hydroxide or a hydratable alkaline earth metal oxide in amounts so as to provide an overall composition including greater than about 3.5 weight percent alkaline earth metal oxide or hydroxide, that amount being based on an equivalent amount of alkaline earth metal oxide, on a dry weight and additive basis, and continuing the mixing of the overall composition for a period of time sufficient to provide a degree of mixing at least equivalent to about thirty seconds in a Hobart planetary mixer, at first speed, whereby the overall composition is mixed to a degree at least approaching the thixotropic state therefore. The compositions produced by this process have improved compressive strengths and significantly reduced permeability coefficients of less than about 1.0.times.10.sup. -7 cm/sec.

摘要： A system for forming a reaction product such as calcium silicate comprises an autoclave for receiving the reaction constituents and for reacting these constituents to form a reaction product, a holding vessel for receiving the reaction product and a flow passage connecting the autoclave to the holding vessel and for allowing the passage of the reaction product from the autoclave to the holding vessel. The flow passage includes a heat exchanger for transferring heat from the reaction product during its passage through the flow passage to another medium. The system includes an electronic control system for maintaining the pressure in the holding vessel a controlled amount beneath the pressure in the autoclave during the transfer of the reaction product from the autoclave to the holding vessel. This minimizes the structural damage to the reaction product during its transfer to the holding vessel. The holding vessel can, if desired, be used to mix additional material into the reaction product.
