Impact of carbonation and fiber hornification on the performance of fiber-cements

The present study evaluates the effect and advantages of the combined use of two treatments on fiber-cement composites: 1) accelerated carbonation on the cement matrix and 2) hornification of commercially used unbleached pine pulp (Pinus radiata D. Don). The premise of the study was to develop a com...
