Abstract
The rapid development of the concrete industry consumes many natural resources and has many negative impacts on the environment. Large numbers of research attempts are focused on finding alternatives to cement and sand for use in concrete mixes to improve the sustainability of concrete. Wollastonite microfibers comprise a calcium metasilicate minerals with a wide range of sources and can be used as cement substitutes in cementitious composites, which has attracted worldwide attention in recent years. This paper presents the state-of-the-art research on the properties of cementitious composites containing wollastonite microfibers as partial cement replacement from the following aspects: setting time, workability, mechanical properties, shrinkage, durability, microstructural properties, environmental and economic analysis, and future prospects. The literature review confirms the feasibility of using wollastonite microfiber as a partial substitute for cement in cementitious composites, but this research still needs to be further studied and discussed.
