Fiber-matrix interactions in cement mortar composites reinforced with cellulosic fibers

With the aim of gaining a better understanding of the phenomena responsible of the loss of durability of cement mortar composites reinforced with vegetable fibers, this paper focuses on the analysis of the fiber-matrix interactions. More specifically we analyze the effects of the vegetable fibers on...
