Carbon fibre material has a wide range of applications, as it can be formed at various densities in limitless shapes and sizes. Carbon fibre is often shaped into tubing, fabric, and cloth and can be custom-formed into any number of composite parts and pieces. While carbon fibres have been used in cement slurry and concrete, textile-reinforced mortars (TRM), fibre-reinforced cementitious mortars (FRCM) or fabric reinforced cementitious matrix (FRCM) may prove to be an engineering breakthrough.

= History =

Since 2000, textile-reinforced mortars have been explored as a potential replacement for fibre reinforced polymer (FRP) methods of reinforcing concrete. Generally, TRM has demonstrated its ability to strengthen concrete and masonry structures in a manner that offers protection from seismic activity. With the addition of thermal insulation materials, TRM may prove to be a valuable for building envelope energy retrofit purposes.

= KICT TRM =

In 2018, researchers from the Korea Institute of Civil Engineering and Building Technology (KICT) led by Dr. Hyeong-Yeol Kim, began developing a structural engineering method that combined a carbon fibre grid with cement mortar to create a new type of textile-reinforced mortar. In November 2020, a patent for the technique was granted.

Carbon fibre sheets have historically been used to strengthen structurally deficient concrete structures. However, the KICT TRM sheets are typically applied with adhesives that can become dangerous in the event of fire. Second, the sheets do not work well if applied on wet surfaces (they may even fall from the structure if they become too wet).

== Thin panels ==

TRM produced through the KICT method is manufactured in thin precast panels made from a carbon fibre grid and a layer of cement mortar. It can then be applied as cast-in-place construction.

Using this technique, thin TRM panels (approximately 20 mm-thick) are put on the surface of the structure. The space between the panel and the existing surface is filled with cement grout which acts as an adhesive.

The carbon fibres and the cement mortar are highly resistant to fire and are generally considered noncombustible materials. This method can be applied during any weather conditions and the panels will stay in place even if water is trapped between the surfaces.

== Test results ==

Tests conducted by the research team indicated that the failure load of concrete structures strengthened with the TRC panel increased by at least 1.5 times compared to that of a conventional structure.

The durability test and analysis of the TRM panel indicates that the lifespan of the panel is more than 100 years. This increase can be attributed to the cement mortar, developed by KICT, which contains 50% ground granulated blast furnace slag, an industrial byproduct generated at ironworks.

== Applications ==

This method of construction using TRM panels may be suitable for building facades or repairs. It could also be used as strengthening materials for other applications, such as highway facilities, car parks or other structures where there is exposure to weather extremes.

== Production ==

The cement mortar used in the KICT process is generally less expensive than conventional mortar. This may reduce construction costs by about 40% compared to existing carbon sheet attachment methods.
