Fabrication and Mechanical Behavior of Portland Cement Mortars Reinforced with Ichu Fibers

Abstract:

Reinforced Portland cement mortars were manufactured using a mixture of type I cement, fine sand, Ichu (in variable percentages) and water, it was possible to verify the influence of the addition of Ichu fibers on the mechanical response in uniaxial compression of the mortars studied. The mechanical results found revealed a systematic reduction of the maximum mechanical resistance by increasing the volume of Ichu fibers added in the studied mortar mixtures, on the other hand, a greater degree of deformation was evidenced in mortar mixtures with a greater quantity of Ichu fibers added, reaching deformation values of up to 10%. The maximum resistance values found were 0.4 to 3.6 MPa for samples with 16 and 4 Vol.% Of Ichu added, respectively. The microstructure of the mortars studied consisted of a continuous cement binder phase with sand particles and short Ichu fibers dispersed within the binder phase. The real density and average porosity of the mortars reinforced with Ichu was 2.59 g / cm3 and 41%, respectively.
