Research on fabrication of non-metallic fiber reinforced concrete used in sea and island construction

Abstract

Concrete is a brittle material with high compressive strength, tensile strength and low deformation capacity. In fact, concrete and reinforced concrete structures are often destroyed due to brittleness. To overcome this drawback, the research using a fiber-reinforced concrete in construction projects is receiving increasing attention. Short fibers such as metal fibers, synthetic fibers and natural fibers added to the composition of concrete will increase the tensile capacity, enhances the impact resistance of the structure, improving the durability and service life of the project. The research of non-metallic fiber reinforced concrete - an environmentally friendly material, to increase bending, tensile and impact strength, increase the corrosion resistance of concrete in aggressive environments...will increase the service life of the project. This paper introduces some research results that bring high economic and technical efficiency by using non-metallic fiber (Polyvinylal Alcohol Fiber) to manufacture fiber reinforced concrete for thin-walled precast components and construction in Vietnam’s island and coastal areas.
