Abstract Scope |
Guaruman fiber is a natural lignocellulosic fiber (NFL) extracted from the stalk of an Amazon plant (Ishinosiphon Koern), in the northern region of Brazil. The present work investigates the addition of 2.5, 5.0 and 7.5 wt% of guaruman fiber, into cement for a reference mortar. The fibers were mercerized in NaOH solution for improved adhesion to a mortar matrix made with 1:1:6 ratio of ordinary Portland cement, lime and natural sand. Technical properties of mass density, consistency, incorporated air content and water retention were evaluated for the as-processed fresh state of the mortar reinforced with this NFL. The preliminary results in association with the relatively low mass density of the mortars incorporated with NaOH-treated guaruman fibers reveal a promising material to be applied as mortar for wall covering in civil construction, in a proportion of 7.5 wt%, which shows a great potential for the use of this fiber. |
