Density and Absorption Properties of the Magnesium Oxide matrix Including the Modified Sulfur According to the Addition Ratio of the Wood Powder and Pearlite

Recently, the trend for structure is being changed from wall construction to rhamen construction. rhgamen construction reduces floor noise and selfweight in structures. The amount of lightweight panels used in rhamen construction is also increasing. Also, Worldwide refinery industry is a large amount of sulfur is produced by develrop ment. Sulfur is resistant to freezing and thawing. Terefore, this study focuses on the density and absorption of magnesium oxide matrix that contains wood powder and pearlite to replace lightweight panel for rhamen construction. Adding pearlite 15% has the lowest density but, it has the highest absorption.
