| Abstract |
In order to minimize the environmental load of the construction industry, it is necessary to strengthen the eco-friendliness of building
materials and extend the durability and lifespan of new construction and demolition. Therefore, many methods of finishing the roofing
materials of hanok have been reviewed and the problems have been improved, but the existing method is being used as it is due to
problems such as economic feasibility, weight, and hardness. Clay and kaolin produced in Gyeongju, and fine powder of ferronickel slag
(FNS), a recycled resource, were added to the clay roof tile manufacturing method to review the properties and color change effect as a
representative roofing material in Korea, and to improve the pollution resistance of buildings with ceramic nano coating I tried to solve the
problem to improve. As a result, the flexural strength of the eco-friendly clay roof tile fired at 1025 ℃ low temperature was 2800N or more
and the water absorption rate was 9%, which satisfies the quality standards of KS F 3510, the contact angle is 135.95 degrees, and the color
is 40 CIE * L, confirming the characteristics of the eco-friendly clay roof tile. |
