“…Therefore, further research is required to understand current climate change effects on concrete performance. Among many possible solutions to enhance concrete performance, one solution of improving performance of concrete mixture in terms of durability, toughness, and mechanical strength is using fiber-reinforced concrete (FRC) [24][25][26][27][28][29][30][31]. …”

Abstract:Recently, the manifestation of global warming-induced climate change has been observed through super typhoons, heavy snowfalls, torrential rains, and extended heat waves. These climate changes have been occurring all over the world and natural disasters have caused severe damage and deterioration of concrete structures and infrastructure. In an effort to deal with these problems due to extreme and abnormal climate changes, studies have been conducted to develop construction technologies and design guidelines. Nevertheless, study results applicable to construction sites continue to be ineffective and insufficient. Therefore, this study proposes ways to cope with climate change by considering the effect of concrete curing condition variations on concrete material performance. More specifically, the 3-, 7-and 28-day compressive and split tensile strength properties of concrete mix cured under various climatic factors including temperature, relative humidity, wind speed, and sunlight exposure time were evaluated to determine whether the concrete meets the current design requirements. Thereafter, a performance based evaluation (PBE) was performed using satisfaction probabilities based on the test values to understand the problems associated with the current mix proportion design practice and to identify countermeasures to deal with climate change-induced curing conditions.

“…The initial cross-section dimension of rope is taken in calculation of its stress. Rope of 36 mm diameter is having a tensile strength and ultimate elongation of 15.3 MPa and 190%, respectively, (29). It is important to note that the rope undergoes an elongation of 163% at peak load (first rupture).…”

“…The concept of finding flexural toughness is taken from Richardson et al (28). Coconut fibre rope is tested in Avery machine to determine its tensile strength and modulus of elasticity (29). CFRC interlocking blocks were also tested in compression testing machine for their compressive strength, elastic modulus, compressive toughness and Poisson's ratio (30).…”

Earthquake-resistant and economical housing is the most desirable need in rural areas of developing countries. These regions often suffer significant loss of life during a seismic event. To enable an efficient and cost-effective solution, a new concept of construction, i.e. a wallette of interlocking blocks with movability at the interface and rope reinforcement, is investigated. The novel interlocking block is made of coconut fibre reinforced concrete (CFRC). The reason for using coconut fibre is their highest toughness amongst natural fibres. This paper describes the in-plane behaviour of the interlocking wallette under earthquake loadings. The wallette response is measured in terms of induced acceleration, block uplift, top maximum relative displacement and rope tension. The applied earthquake loadings cannot produce any damage in the structure, i.e. blocks and/or ropes. The response of the wallette is explained in detail along with correlation of materials aspect with structural behaviour. RESUMEN: Uso de hormigón reforzado con fibras de coco para construcciones sismo resistentes.En las zonas rurales de los países en desarrollo, entre las características principales que deben reunir las viviendas es que sean tanto económicas como sismoresistentes, ya que en estas zonas la pérdida de vidas humanas debido a los terremotos es aun elevada. A fin de hallar una solución que cumple con estos requisitos de manera técnica y económicamente efectiva, se ha investigado un nuevo concepto constructivo: un murete de bloques conjugados con movilidad en el interfaz y reforzado con cuerda. Este novedoso bloque conjugable está realizado en hormigón reforzado con fibra de coco (CFRC), elegida por su alta tenacidad, la mayor de entre las fibras naturales. El artículo describe el comportamiento dentro del plano del murete conjugado frente a las cargas sísmicas. La respuesta de esta estructura se ha medido en función de la aceleración inducida, el levantamiento de los bloques, el desplazamiento relativo máximo y la tensión de las cuerdas, determinándose que ni los bloques ni las cuerdas han resultado dañados por las cargas sísmicas aplicadas. La respuesta del murete se describe en detalle, relacionando las propiedades de los materiales con su comportamiento estructural.

This century has witnessed remarkable achievements in green technology in material science through the development of natural fiber reinforced composites. The development of high performance engineering products made from natural resources is increasing worldwide day by day. There is increasing interest in materials demonstrating efficient use of renewable resources. Nowadays, more than ever, companies are faced with opportunities and choices in material innovations. Due to the challenges of petroleumbased products and the need to find renewable solutions, more and more companies are looking at natural fiber composite materials. The primary driving forces for new biocomposite materials are the cost of natural fibers (currently priced at onethird of the cost of glass fiber or less), weight reduction (these fibers are half the weight of glass fiber), recycling (natural fiber composites are easier to recycle) and the desire for green products. This Review provides an overview of natural fiber reinfocred composites focusing on natural fiber types and sources, processing methods, modification of fibers, matrices (petrochemical and renewable), and their mechanical performance. It also focuses on future research, recent developments and applications and concludes with key issues that need to be resolved. This article critically summarizes the essential findings of the mostly readily utilized reinforced natural fibers in polymeric composite materials and their performance from 2000 to 2013.
