Abstract
Trends in the Addition of PET and Natural Fibers to the Concrete- Steel Reinforcement System
Highlights
The construction industry consumes large amounts of raw material and energy, contributing greatly to environmental pollution, mainly favoring the release of greenhouse gases (GEI) [1]
It is known that the corrosion of reinforcing steel embedded in concrete is one of the main causes of its deterioration, it is an electrochemical process and for many years efforts and arduous studies have been directed in search of improving the electrochemical and mechanical properties of the concrete-reinforcing steel system
The results were as follows: reference specimen, compressive strength of 31.14 MPa, bending strength 5.02 MPa, tensile breaking resistance of 2.08 MPa, while specimens with 2%, 3% hemp with 12 mm length reported compressive strengths of 34.28 MPa, 34.67 MPa, at flexion of 5.47 MPa, 5.82 MPa and tensile breakage of 3.71 MPa and 4.10 MPa. This represents a 10-15% increase in mechanical properties directly related to the presence of natural fiber of 2%, 3% replacing the fine aggregate in concrete
Summary
The construction industry consumes large amounts of raw material and energy, contributing greatly to environmental (atmospheric) pollution, mainly favoring the release of greenhouse gases (GEI) [1].
