The outstanding mechanical properties of basalt fiber make it become attractive candidate in the soil reinforcement field. The impact of the above subject has influenced diverse investigations into the effects of MK and basalt fiber on the mechanical properties and reinforcing mechanism of cement soil under standard temperature curing condition.
The raw material for basalt fibre (andesitic basalt, andesite basalt, diabase and other volcanic rock) belongs to the family of inorganic nonmetallic silicates and is characterized by high Fe 2 O 3 or FeO content. The high Fe 2 O 3 /FeO content in turn leads to a high melt blackness coefficient, poor diathermancy, and the need for high crystallization temperature and …

To enhance the strength and toughness of geopolymers, a type of basalt fiber is incorporated into the geopolymer matrix as a reinforcing material. Basalt fibers chosen in this study are 3 mm in length and 7–15 μm in diameter. The physical properties of basalt fiber are shown in Table 3.
Basalt fiber (BF) is a natural fiber prepared entirely from volcanic rock. Its mechanical properties are superior to those of vegetal fibers, and similar or superior to those of glass fiber [25] . Sim et al. [26] reported that the reduction in strength of BF was less significant compared to that of carbon and glass fibers up to 600 ℃.
The raw material of basalt fiber is basalt, mainly composed of SiO 2 and Al 2 O 3. The SiO 2 content reaches 45% to 60% and has a composition similar to that of silicate cement. Although the surface of basalt fiber is smooth, it has a natural compatibility with cement .
Basalt fibers are obtained from basalt rocks that are formed in the earth's crust. Basalt rocks are found all over the world [63]. In the roman age, basalt stones were used as paving stones. In 1923, a French national, Paul Dhe extruded fiber from basalt and was subsequently awarded a US patent [63].
The low alkali resistance of basalt fiber limits its utilization in the strong alkaline environment such as cement and concrete as the reinforcing material. Adding additive in the basalt rocks is the feasible method to enhance the alkali resistance. However, it is necessary to develop the efficient additive for basalt fiber.
Zirconium-rich basalt fibers have excellent alkali resistance, however, due to the extremely high melting points of the zirconium sources used (ZrO 2 and ZrSiO 4), it is very difficult to incorporate them uniformly into the basalt melt.This may lead to a significant number of microcrystals in the prepared zirconium-rich fibers, which seriously reduces the mechanical …
