Universal siliceous castable
The invention discloses universal siliceous castable prepared from raw materials including waste silica bricks, quartz powder, silicon dioxide micro powder, Portland cement, high-alumina cement and efficient water reducing agents according to a certain ratio. Waste silica brick particles are used as skeletal materials of the siliceous castable. Main mineral phases of a construction body where pouring is conducted include the tridymite phase and the cristobalite phase. Cracking or stripping caused by large crystal transfer can not be generated. The silicon dioxide micro powder which is used as reinforcing agents and agglomerant as well is used, and therefore the normal temperature strength is improved, and the high temperature sintering performance is improved as well. The Portland cement is adopted as a binding agent, and conversion of residual quartz into tridymite and cristobalite can be promoted under the high temperature. The castable can be directly used under the high temperature after being constructed, the use performance is close to the performance of silica bricks, the overall performance of the castable is superior to that of a construction body spliced and built by small bricks, large-size siliceous cast-in-place construction bodies or prefabricated pieces good in overall performance can be manufactured, and great breakthrough is achieved on the aspect of siliceous castable.
