摘要：
The effects of metakaolin (MK) and basalt fiber (BF) on the performance of gypsum-based composites were investigated. BFs 6 and 12 mm long were used in concentrations of up to 0.8 wt.%. Mechanical tests were conducted on both dry and water-saturated specimens. It was found that their flexural and compressive strengths increased with content of BFs to 0.6%. However, the mechanical and durability properties worsened with fiber addition up to 0.8%. The samples with the 6-mm-long BFs showed better properties than those with the 12-mm-long ones. The addition of MK improved the shrinkage behavior of the composites, which could hinder an early formation of cracks in them.
