Abstract

This paper assesses for the first time the effect of accelerated carbonation and hornification treatments on fiber-cement composites, both combined and independently. In order to improve the mechanical performance and durability of the material, the influence of each treatment over matrix and fiber is analyzed along time. The results indicate that hornification treatment yields greater dimensional stability improving the fiber-matrix interface and greater Specific Energy of the composites, while accelerated carbonation generates denser matrices, which increases Modulus of Rupture. After accelerated aging, the combined effect of both treatments improved the mechanical performance compared to the rest of the samples. In addition, cellulose material is preserved, showing the potential efficiency of both treatments combined on fiber/matrix. (C) 2019 Elsevier Ltd. All rights reserved. (AU)
