Overview

Textile reinforced mortars (TRM) have emerged besides fabric reinforced polymers (FRP) composites for structural strengthening in the construction industry due to their better compatibility with concrete and masonry materials and lower sensitivity to high temperature. This PhD project aims at manufacturing, testing, and modelling novel bio-TRM composites with reduced CO2 impact for strengthening masonry and concrete structures.

Textile reinforced mortar composites are particularly suited to strengthen unreinforced masonry structures such as heritage constructions and ordinary buildings subjected to seismic excitation. However, the market of these composites are currently dominated by synthetic fibres such as carbon, plastic and glass fibres, which have a high environmental impact and make it difficult for low-income countries to avail of this strengthening method. Contrary to synthetic fibres, natural fibres are affordable and readily available in most countries. The fabric manufacturing has a low CO2 footprint and the products are recyclable and biodegradable by the end of their life cycle.
While they have already entered the automobile sector as reinforcement for FRP composites, flax, jute and hemp are not yet used in the construction field.

This PhD project aims therefore at addressing two main goals:
1) Investigate new bio-TRM composites made with bio-based materials such as hemp/flax/jute and mortars containing waste materials. In particular assess the mortar/fabric bond, and the long term compatibility of reinforcement and matrix.
2) Test the composite mechanical properties in terms of tensile and bond behaviour with the substrate (masonry/concrete) and model the mechanical interaction between mortar and reinforcement.
