Hydraulic composition
专利汇可以提供Hydraulic composition专利检索，专利查询，专利分析的服务。并且An hydraulic composition for setting or hardening soils comprising 100 parts by weight of a component A and 6 to 10 parts by weight of a component B. Component A is the product obtained by calcining a mixture of the following constituents: 100 parts by weight of limestone; 3 to 6 parts by weight of alumina; 15 to 30 parts by weight of silica; 4 to 10 parts by weight of magnesium oxide; 5 to 10 parts by weight of iron oxides; and 5 to 10 parts by weight of magnesium chloride. This mixture is preferably calcined at a temperature between about 1,000* and about 1,300* C. and is thereafter rapidly cooled to a temperature below about 100* C. The calcined granules so produced are pulverized and mixed with component B having the following preferred composition: 79 parts by weight of calcium sulphate; 55 to 75 parts by weight of an alkaline earth metal chloride; 5 to 10 parts by weight of an alkali metal silicofluoride; 10 to 20 parts by weight of an alkali metal carbonate; 10 to 20 parts by weight of a buffering agent; 30 to 50 parts by weight of lignin sulfonate. A further improvement can be made by adding a component C to the mixture of components A and B. Component C has the following composition: 100 parts by weight of at least one member selected from the group consisting of weathered granite soil calcined at 700* to 900* C., decomposed basalt soil calcined at 300* to 500* C., and volcanic ashes or decomposed andesite soil calcined at 300* to 500* C.; and 40 to 60 parts by weight of at least one member selected from the group consisting of sand or pozzolan gravel calcined at 200* to 300* C., limestone residue which comprises overheated calcined residue which is not returned to slaked lime in the presence of water, calcined at 200* to 300* C., calcium hydroxide calcined at 200* to 300* C., nickel blast furnace slag calcined at 200* to 300* C., and the residue of electrolytic refining of aluminum calcined at 200* to 300* C. Component C is preferably employed in the range of about 10 parts by weight to about 20 parts by weight per 100 parts by weight of component A.，下面是Hydraulic composition专利的具体信息内容。
