Trend in civil construction: use of unconventional materials
Posted: Mon Dec 23, 2024 5:55 am
The exorbitant increase in the cost of inputs, especially steel, has led to the need for debate about new materials and new construction processes. What is the new trend in civil construction?
The aim of this article is to shed some light on this debate, particularly with regard to the use of unconventional materials applied to concrete structures, such as FRP (fiber reinforced polymer).
Technical Committee 303 reveals new trend in civil construction

For those who work in teaching, research and extension, this is not a buy smart number issue. An example of this is the Technical Committee 303 IBRACON/ABECE, which was created in 2015, with the mission of promoting the integration of the various sectors of the use of non-conventional materials for reinforcing concrete structures (structural reinforcement, non-metallic reinforcement and fiber-reinforced concrete), aiming at the integration of the projects and materials sector ( ABECE ).
This committee brings together several researchers, product suppliers, designers and construction companies. It deals with four specific working groups. They are:
Fiber reinforced concrete structures – with technical standard already published since the beginning of 2021.
Non-metallic reinforcement for use in concrete structures – with recommended practice already published for reinforced concrete structures with fiber reinforced polymer (FRP) bars.
Ultra-high performance concretes reinforced with fibers – with practical results expected to be published at the next IBRACON (Brazilian Concrete Institute) congress.
Reinforcement of structures with externally applied elements.
Technical committees are very important for the development of technical standards in Brazil. FRP, for example, does not yet have a published technical standard, but it is already being developed by Technical Committee 303. This is a practice already recommended in Brazil, and there are international standards on FRP, such as Canadian standards that provide guidelines for the design of structures using this reinforcement ( CSA S806 ).
