Structural Behavior of Small-Scale Masonry Panel with Fiber Reinforced Mortar under Compressive Load

Abstract

The use of fiber reinforced mortar for structural retrofitting/new construction of masonry structures has become increasingly popular in the last years. A preliminary study on the mechanical performances under compression of masonry panels is performed by selecting three different mortar types. The panels were composed of mortar and clay bricks; the mortars adopted are the following: i) commercial type mortar, ii) traditional mortar and iii) traditional mortar with the addition of a cellulose-based industrial non-hazardous waste. In particular, the study proposes the use of deink paper sludge as mortar filler as an example of sustainable end-of-life reuse. Using the collected experimental results involving the mortars and clay brick form a regression analysis on compressive strengths was performed in order to evaluate the influence of the deink paper sludge on the compressive behavior of the panel.

Cement-Based Mortars with Waste Paper Sludge-Derived Cellulose Fibers for Building Applications

“…For instance, the mortar incorporating 1% of cellu- It is worth mentioning that a dimensional analysis of the ground paper sludge was performed by the authors in a previous experimental campaign. Further information about this aspect can be found in [24].…”

Mechanical and Physical Characterization of Papercrete as New Eco-Friendly Construction Material

“…Therefore, waste paper and paper sludge also deinked are suitable to become a future building material in the concrete industry for lightweight applications thanks to its low cost and high recycle paper content [10][11][12], presenting also different properties such as the ratio of the virginrecycled paper used as the raw material, the ratio between organic (non-recovered cellulose) and inorganic (principally, kaolinite and limestone) components. Recently, experimental investigations [13] of masonry panels composed of mortars including cellulose fibers from deinked paper sludge were conducted in order to evaluate the influence of paper sludge on the compressive behavior of panels.…”
