Abstract
This dissertation presents a systematic literature review about the utilisation of ultrahigh-performance fiber-reinforced concrete (UHPFRC) to repair and strengthen
damaged concrete . There are two objectives of this review. First is to identify the
different cases of concrete deterioration and the corresponding utilization of UHPFRC
in the repair and strengthening applications. The next objective is to compare and assess
the effectiveness ofthe use of UHPFRCin differentrepair and strengtheningapplications
based on the available literatures. UHPFRC is a cementitious composite that has
compressive strength higher than 150 MPa. The high strength of the concrete is thanks
to its high cement content, making it suitable to be used as repair material. From the
Scopus database, there were 12 articles that had been identified for this review.
Systematic searching strategies was used to filter out irrelevant articles and the articles
are filtered again through quality assessment to further remove low quality articles. In
this review, the usage of UHPFRC that is used to repair different cases of concrete
deterioration were discussed. From the articles reviewed, it showed that UHPFRC is
already widely used for treating concrete damaged by corrosion, cracking and ASR.
Also, various kind of methods were used to apply the UHPFRC onto the damaged
concrete. Based on the studies reviewed, the effectiveness of the repaired concrete was
found to be acceptable.Although UHPFRChave high compressive strength, the selection
of repair material should be based on the deformation mechanism, site condition, and
client requirement because different repair materials come with different advantages and
disadvantages. Knowing these properties should be helpful to decide the most suitable
material needed for repair works.
