Title:
SELF-HEATING CERAMIC MORTAR COMPOSITION REPARABLE IN COLD WINTER ENVIRONMENT AND REFRIGERATED WAREHOUSE FLOOR, AND METHOD FOR CONSTRUCTING WINTER CONCRETE STRUCTURE USING SAME
Document Type and Number:
WIPO Patent Application WO/2021/075776
Kind Code:
A1
Abstract:
The present invention pertains to: a self-heating high-performance ceramic mortar composition which can be repaired in the cold winter season and in refrigerated warehouses below -20°C; and a method for constructing a winter concrete structure using same. Since a hydration reaction proceeds even at low temperatures and initial exothermic reaction proceeds rapidly on the basis of the basic mechanism of a ceramic cured body rapidly reacting and forming chemical bonds via an acid-base reaction of magnesium oxide and phosphate, the self-heating ceramic mortar self-cures without freezing in even cryogenic conditions through heat self-generated during curing, and has early strength properties, impermeability, excellent insulation properties, and almost no contraction and expansion, and thus is a high-performance ceramic mortar composition which can be repaired in the cold winter season and in refrigerated warehouses below -20°C. The self-heating ceramic mortar contains 15-30 parts by weight of magnesia (MgO), 20-40 parts by weight of phosphate, 1-10 parts by weight of a heat accelerator, 5-20 parts by weight of wollastonite, 5-15 parts by weight of an inorganic binder, 5-10 parts by weight of cenosphere, 30-55 parts by weight of silica sand, and 10-20 parts by weight of a functional additive.
