Abstract
This study was designed to solve the problem of magnesium hazards due to potash extraction in the salt lake
region. Using basalt fiber (BF) as the reinforcement material and magnesium oxychloride cement (MOC) as
the gelling material, a BF/MOC composite material was prepared. Firstly, the effect of BF addition content on
the basic mechanical properties of the composites was investigated. Then, through the salt spray corrosion test,
the durability damage deterioration evaluation analysis was carried out from both macroscopic and microscopic
aspects using mass change, relative dynamic modulus of elasticity (RDME) change, SEM analysis and FT-IR analysis. Finally, a GM(1, 1)-Markov model was established to predict the durability life of composite materials by
using durability evaluation indicators. The results show that: when the BF content is 0.10% (by volumetric content), the composites have the best mechanical properties and resistance to salt spray corrosion. However, when
the volume of BF content exceeds 0.10%, a large number of magnesium salt crystallization products are observed
from the microscopic point of view, and the corrosion of the main strength phase of MOC is more serious. The
prediction results of the GM(1, 1)-Markov model are highly identical with the raw data. In addition, using the
change of RDME as a predictor, RDME is more sensitive to environmental factor compared to the change of
mass. Predictions using the change of RDME as a threshold indicate that MOC-BF0.10 has the longest durability
life, which is 836 days. The model is important to promote the application of MOC composites in the salt lake
region and to promote the healthy development of green building materials.
