Calcium carbonate whisker is an emerging class of inorganic fiber having tremendous properties and vast applications. Calcium carbonate whisker is extensively used as a filler due to its tremendous properties including low price, simple preparation requirements and ease of availability. As a filler, it increases the physical and chemical properties such as heat resistance, strength and modulus. Its unique properties are seeking the attention of researchers for utilizing it as a filler in various applications. In this paper, different basic preparation techniques of calcium carbonate whisker such as metathesis reaction, sol-gel, carbonation, gravity crystallization and urea hydrolysis are described briefly. In addition to this, the review focus on research advancements achieved in the utilization of calcium carbonate whisker in different applications such as friction materials, paper making, reinforcing composite materials, cement, mortar and concrete. Calcium carbonate whisker is mostly used for enhancing the properties of cementitious materials. In this review, a special emphasis is given to the role of whisker in cementitious materials such as cement, concrete and mortar.
