With the promotion of carbon neutral policies, 1,2 stricter regulations have been issued regarding environmental protection during the production of different kinds of materials. 3,4 The continuous basalt fibers (CBFs), 5,6 produced by the natural basalt rock, 7 have been regarded as "The 21st-century non-pollution green materials" 8 because no …
This increases cement clinker production. The composition of limestone as the main raw material required in the manufacture of clinker is 81%. Basalt is used as an alternative raw material because it contains SiO2, Al2O3, and Fe2O3 with a total of >70%. It meets the chemical requirements of ASTM C618 as a substitute material for cement making.

Basalt is an igneous rock that developed during the cooling of magma during the earth's early eras. A pozzolana is a substance capable of interacting with calcium hydroxide (Ca (OH) 2) in the presence of water at room temperature to produce cementitious compounds (as C-S-H gel) []. In recent years, many researches were investigated that the use supplementary …
