Strengthening of Unreinforced Masonry with Fibre Reinforced Concrete

Unreinforced Masonry buildings are vulnerable because the walls and parapets aren’t securely tried to the floors and roof. In an earthquake, parapets can break away, walls pull apart and the floors collapse. This paper presents the experimental study performed on the flexural bond strength of unreinforced brick masonry prism. Different percentage (1%, 2%, and 3%) of Hooked Steel Fibre was used. One of the most geometrical parameters of fibres is their length, diameter and aspect ratio. Masonry prism will be cast and tested as per the guidelines are given in ASTM E518/E518-15. The results of the flexural bond strength test of prisms with and without fibre discussed.

Masonry Prism

Unreinforced brickwork (URM) is the most established development method. URM being weak can't withstand the parallel burdens amid a seismic region. Consequently, it is important to locate an appropriate low-cost technique to fortify existing brickwork structures. In this paper flexural bond strength test was conducted on the rectangular brick masonry prisms with two types of welded wire meshes (epoxy coated mesh with the spacing of 12mm and galvanized iron wire mesh with the spacing of 15mm). Masonry prisms were cast and tested as per the guidelines are given in ASTM E518 /E518-15 standards. The results of the flexural bond strength embedded masonry prism show greater when comparing the prisms with no mesh embedment.

Strength And Durability

The concrete microstructure can affect its macroscopic properties, such as the strength and durability, etc. Based on the experimental study of cube compressive strength of steel fibre reinforced concrete, splitting tensile strength, flexural strength, and using by mercury intrusion method to test the pore structure of steel fibrous, this paper analyzes the influence of fibre on concrete pore structure. And then on mechanical properties of concrete from microcosmic perspective.
