This study was performed in the framework of a research program focused in the development of high tenacity polypropylene (PP) fibres for the reinforcement of cementitious composites. Precedent reports have demonstrated how micromechanical modelling was used to attain significant improvements with respect to the macroscopic properties of cementitious composites. These improvements have been bas...

Engineered Cementitious Composite (ECC) is a special type of HPFRCC designed using micromechanics concepts which take into account the mechanical interactions between fiber, matrix and interface in deformation processes under load. While the properties of ECC have been extensively investigated, the interaction between ECC and steel reinforcement has not been studied. This interaction is importa...

In this paper, the inelastic damage process in Engineered Cementitious Composites (ECC) in the high stress concentration zone adjacent to the head of an embedded anchor under tensile load was examined experimentally and numerically. An FEM model together with a tensile strain-hardening material model of ECC was developed to simulate the damage process leading to final failure. Experimental obse...

Fiber-reinforced cementitious composites (FRCC) have emerged as a promising alternative to traditional materials due their enhanced mechanical properties and durability [...]

Efficient maintenance and upgrading of a building during its lifecycle are difficult because a cementitious finish uses materials and parts with low disassembly properties. Additionally, the reuse and recycling processes during building demolition also present numerous problems from the perspective of environmental technology. In this study, an induction heating (IH) method was used to disassem...

Abstract Nanocellulose (NC) is a promising reinforcing material for cementitious composites, but its effect on the mechanical properties of hybrid engineered composites (ECCs) has not been studied. In this paper, we investigated polyethylene (PE)-steel fibre ECC reinforced with NC and dosages ranging from 0.1% to 0.4% compressive strength ECC. The optimum quantity best property was determined. ...
