Abstract Murals in Mogao Grottoes consist of three parts: support layer, earthen
plasters and paint layer. The earthen plasters play a key role in the preservation of
murals. It is a mixture of Dengban soil, sand, and plant fiber. Two different natural
fibers, hemp fiber and cotton fiber, were reinforced to earthen plasters in the same
percentage to evaluate the influence on hygrothermal performance. The two types
of earthen plasters were studied: one containing hemp fiber in the fine plaster
(HFP) and the other containing cotton fiber in the fine plaster (CFP). Specific heat
capacity, dry thermal conductivity, water vapor permeability,… More >
