Mechanical properties, durability and environmental assessment of low-carbon cementitious composite with natural fibrous wollastonite.

Cementitious composite is one of the most widely used construction materials around the world, but cement production is accompanied by energy waste and CO emission. Wollastonite, a natural fibrous silicate mineral, can be a potential supplementary cementing materials (SCMs) for cementitious composite owing to its similar calcium silicate system, and it has an eco-friendly and convenient production process. Furthermore, its unique fibrous structure can possibly act as reinforcement for the cement matrix.
