Abstract null null The durability of the basalt fiber-reinforced polymer (BFRP) bar in an alkaline environment is a major problem that prohibits its use as reinforcement in a marine concrete structure. One potential remedy is to reduce the alkalinity of the concrete. For evaluating the feasibility of this technique, the mechanical durability of BFRP bars was investigated in a simulated seawater sea sand concrete environment using accelerated degradation tests. The interlaminar and transverse she...

Abstract Extensive studies have been conducted on seawater sea-sand concrete (SSSC) in recent years due to the shortage of freshwater and river-sand in many coastal areas. This paper reviews the properties of seawater and sea-sand and their effects on hydration, microstructure and properties of concrete. The relationship between mixture proportion and the hardening properties and durability of SSSC is discussed and optimization of mixture proportion for better performance of SSSC is studied. The...

Abstract The fiber-reinforced polymer (FRP) composites are currently widely used in infrastructure construction, and the study on the dynamic performance and temperature sensitivity is still under investigation. Understanding the effects of strain rate and temperature on the tensile behaviour of FRP composites is vital to design the composite structures under harsh conditions (earthquake, explosion, or impact). Therefore, this study comprehensively reviews tensile performance of FRP composites u...

Abstract Replacing metallic materials (typically carbon steel bars) with fiber reinforced polymer (FRP) composites to reinforce marine concrete structures can effectively resolve the corrosion issue of carbon steel due to external chloride ions and moisture. However, the corrosion-free nature of FRP material cannot guarantee its desirable durability in the marine structures. In order to better understand the durability performance of FRP composites, this paper summarizes the quasi-static tensile...

Abstract Utilization of coral aggregates (CAs) for concrete production can effectively resolve the shortage of raw materials for construction in remote islands and reduce the energy consumption due to the shipping from the mainland. However, the porous nature of CAs and contained salt will affect the mechanical and durability performance of the concrete. This study aims to first summarize the characteristics of CAs and properties of coral aggregate concrete (CAC) and then propose future research...

Abstract Natural protection offered to living beings is the result of millions of years of biological revolution. The protections provided in fishes, armadillos, and turtles by unique hierarchal designs help them to survive in surrounding environments. Natural armors offer protections with outstanding mechanical properties, such as high penetration resistance and toughness to weight ratio. The mechanical properties are not the only key features that make scales unique; they are also highly flexi...

Abstract This study investigates the influence of textile layers on the uniaxial tensile performance of the basalt textile reinforced concretes (BTRCs). The tensile tests were conducted on BTRCs reinforced by three, four and six numbers of basalt textile layers. It was found that the textile reinforcement would enhance the tensile strength, ultimate strain, and total energy absorption of the BTRCs, but also reduced the first crack stress and strain of the cement matrix. Meanwhile, the formation ...

Abstract Textile reinforced concretes (TRCs) have many extraordinary features that make them a future-ready material exposed to complex environmental situations. However, current knowledge related to TRCs under mechanical loading and environmental conditions is not fully explored as compared to conventional fiber reinforced concretes. The present work investigates the quasi-static pullout performance of single-yarn and textile type (AR-glass and basalt fiber) reinforced cement mortars under diff...

Abstract This paper presents a review of the deterioration of concrete under seawater attack with particular interests in field exposure. The research reported in the literature has shown that salinity of seawater in different areas varies considerably but the type of ions and their proportion are similar. Because of this variation, laboratory studies should use specific artificial seawater to simulate on field environments. The phase changes induced by chloride, magnesium and sulfate ions conta...
