Why silica fume is widely used in cement ALOY
2021-2-19 Why silica fume is widely used in cement? Silica ash is a highly reactive volcanic ash with very small particle size. The calcium hydroxide [Ca (OH)2] produced in combination with cement reacts. The small particle size means that the fumed silica fills the space between the cement particles, improving the rheology of the mixture and reducing
