Fiber Reinforced Mortar Mixtures for the Reconstruction and Rehabilitation of Existing Masonry Structures

The aim of this study was to investigate the influences of different parameters on the performance of fiber reinforced polymer (FRP) masonry structures under debris flow using finite element models that were established using the software LS-DYNA. The overall structural responses under the impacts of viscous debris flows were analyzed based on an in-depth parametric study of some key factors (fiber types, relative impact positions, etc.). The results show that the diagonal and intersecting parallel types of FRP arrangements elicit better performances than horizontal types. Use of wider fiber cloths leads to the minimization of the structural response after its impact by debris flow. In addition, glass fiber reinforced polymer (GFRP) yields the best results among all studied materials in reducing local damage, while carbon fiber reinforced polymer (CFRP) yields a better overall structural response. Impact positions at the center of the wall are more unfavorable than those at the corners.

Basalt Fiber Reinforced Polymer

FRP strengthening technique provides a promising alternative for masonry structures. This paper presents research results of quasi-static tests investigating the in-plane mechanical behavior of RC-brick masonry walls with opening strengthened with basalt fiber reinforced polymer (BFRP). Two half scale RC-brick walls were constructed, one without any strengthening scheme served as the reference specimen, another one was directly strengthened with BFRP in mixed strengthening configuration. All specimens were tested under low frequency cyclic loading. BFRP can effectively improve the lateral strength of the wall by a factor of 0.16, and the improvement in the lateral deformation capacity was much significant. The seismic performance of the composite wall strengthened with BFRP can exceed the unreinforced reference, which verifies the effectiveness of BFRP strengthening technique to strengthening RC-brick composite masonry structures in seismically endangered regions.

Mechanical Performances

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.
