Title:
INORGANIC BINDER AND SINTERED BLOCK USING INORGANIC BINDER AND PRODUCTION THEREFOR
Document Type and Number:
Japanese Patent JP3229400
Kind Code:
B2
Abstract:
PURPOSE: To provide an inorganic binder having a self-curing property and presenting a stone-like surface in a half-fused state by firing at a relatively lower temp. and to provide a sintered block excellent in a design property, appearance not impaired by chipping, etc., high slipping resistant value in a wet state, superior in the dimensional stability, and excellent in water absorptive property, while it keeps high strength, by using the inorganic binder as a raw material for the surface layer.
CONSTITUTION: The inorganic binder being formed by mixing 8-46wt.% alumina cement, 5-27wt.% a boric compound expressed in terms of B2O3, 5-70wt.% siliceous material, 5-30wt.% blast furnace slag (but the sum of the above described siliceous material and the blast furnace slag is ≤70wt.%), and 0.5-5wt.% alkali metal compound expressed in terms of R2O (R is Na or /K), is used as raw material for the surface layer, and it is an integrally molded product together with the raw material for base layer and the sintered block in which only the surface layer is a half-fused sintered state, is produced.
