Properties of gypsum composites with shavings

Abstract

Gypsum composites have been gaining increasing interest within last decades. Nowadays, the environment-supporting options are regaining more advocates. Among other solutions, organic fillers are of interest. The physical and mechanical properties of gypsum composites with shavings were tested and are described in the paper. The influence of gypsum mixture composition, the water/gypsum ratio and appropriate mineralization on the composite properties were examined. Present study focuses on the durability, thermal properties, natural radioactivity and susceptibility to biological corrosion of gypsum composites with shavings.

Effect of Fiber Loading on Mechanical and Flame-Retardant Properties of Poplar-Fiber-Reinforced Gypsum Composites

“…In recent years, there have been many attempts to study natural fibers as reinforcement for gypsum-based composites [ 15 , 16 , 18 ], and since natural fibers are environmentally friendly materials, renewable and fully recyclable, and meet the requirements of green building systems, they are commonly used to reinforce highly brittle matrices and are a major application area for construction materials [ 19 ]. Mainly including wood fibers, hemp fibers, hemp stalks, and cotton straw [ 20 , 21 , 22 , 23 ], natural fibers have been studied for reinforcing gypsum-based composites. Hou Zhiyi [ 24 ] et al conducted a systematic study on the mechanical properties of gypsum-based composites with added wood fibers (1, 3, and 5 wt%), and the results showed that the addition of 3-wt% wood fibers significantly improved composite mechanical properties.…”
