Expanded mortar and method for fabricating thereof and repair material method

To the invention Application The requesting a core material and a fire door core material, a refrigerated warehouse floors, fire-resistant coating material such as non-combustible, including thermal insulation, fire resistance of the heat-insulating construction and anti-condensation, Ltd., a composite panel for preventing heat loss caused under the influence from the outside air as to the construction object, the present invention has the advantage of being possible lightweight filler selection of various materials depending on the application required for as for the purpose of improving heat insulating performance in addition to a mixture of magnesium and a curing agent of magnesium oxide at a predetermined ratio by weight as the main ingredient a self-firing due to the catalyst after the construction by about two to four times the initial thickness of the expansion can be fine air layers formed by raised the heat insulating performance. Initially for rapid foaming reaction to avoid lowering the workability, induced the construction reviews foaming the bubble generating agents in use, and at least achieve a uniform bubbling by inhibiting cell growth. There are advantages that can reduce the air to reduce the curing time compared to conventional wet product is non-combustible insulation with excellent thermal conductivity than the typical combustible insulation EPS.
