Effect of accelerated carbonation on the microstructure and physical properties of hybrid fiber-cement composites

Carbonation takes place in the fiber-cement composites through the diffusion of carbon dioxide (CO2) through the unsaturated pores of the cement matrix, and through its reaction with the hydration products of the Portland cement (mainly calcium hydroxide and CSH phases). The use of this technology in the fiber-cement production consists of an interesting procedure to prematurely decrease the alkalinity of the cement matrix, which is potentially...
