TL;DR: In this paper, the effects of FA addition on the compressive strength f cm and fracture toughness of plain concrete are presented, and the results of the K Ic S and the f cm are convergent qualitatively.
124 citations
TL;DR: It can be concluded that composites with 20% addition of FA are characterized by low permeability and therefore high durability, in matured concretes the smallest cracks occur in composite with the 20% FA additive.
104 citations
TL;DR: In this paper, the fracture toughness during Mode I loading of concretes containing the 0, 20% and 30% addition of class F fly ash (FA), was investigated. And the results of the research show the usefulness of the Digital Image Correlation (DIC) method in experiments of that type.
96 citations
TL;DR: In this paper, the authors presented the results of compressive strength and fracture toughness tests of concrete composite modified with the addition of siliceous fly ash (FA) using the Digital Image Correlation (DIC) system.
79 citations
TL;DR: In this article, the optical and contactless DIC technique was used for the examination of fracture processes in concrete with fly ash under shear loading, and the results showed that unmodified concrete are characterised by greater brittleness, whereas composites made on the basis of the binary binder behave as quasi-plastic materials in the fracture process.

TL;DR: An overview of a diverse range of fibers, their properties, functionality, classification, and various fiber composite manufacturing techniques is presented to discover the optimized fiber-reinforced composite material for significant applications.
Abstract: Composites have been found to be the most promising and discerning material available in this century. Presently, composites reinforced with fibers of synthetic or natural materials are gaining more importance as demands for lightweight materials with high strength for specific applications are growing in the market. Fiber-reinforced polymer composite offers not only high strength to weight ratio, but also reveals exceptional properties such as high durability; stiffness; damping property; flexural strength; and resistance to corrosion, wear, impact, and fire. These wide ranges of diverse features have led composite materials to find applications in mechanical, construction, aerospace, automobile, biomedical, marine, and many other manufacturing industries. Performance of composite materials predominantly depends on their constituent elements and manufacturing techniques, therefore, functional properties of various fibers available worldwide, their classifications, and the manufacturing techniques used to fabricate the composite materials need to be studied in order to figure out the optimized characteristic of the material for the desired application. An overview of a diverse range of fibers, their properties, functionality, classification, and various fiber composite manufacturing techniques is presented to discover the optimized fiber-reinforced composite material for significant applications. Their exceptional performance in the numerous fields of applications have made fiber-reinforced composite materials a promising alternative over solitary metals or alloys.

TL;DR: The increasing demand for green concrete has been spurred by demand for high quality concrete products, desire of nations to reduce green-house gas emission, need for conservation of natural resources and limited landfill spaces as mentioned in this paper.
221 citations
TL;DR: In this paper, the crack propagation behavior of the filled and unfilled crack is studied and compared by testing rock-like specimens subjected to uniaxial compression, where crack propagation paths are described where crack is classified into four types, namely the original, secondary, wing and anti-wing cracks.
168 citations
TL;DR: In this paper, the effects of roller compacted concrete (RCC) characteristics on their fracture behavior in both pure mode I and II are experimentally investigated, and the fracture toughness results revealed concrete mix specifications had a noticeable impact on the cracking initiation of RCC and the effect of substituting of waste materials with natural aggregates was found to be negative, although their behavior was still comparable to those obtained for control mixes.
144 citations
TL;DR: In this article, the effect of nano silica on the short term severe durability performance of fly ash based geopolymer concrete (GPC) specimens was investigated, and four types of GPC were produced with two types of low calcium fly ashes (FAI and FAII), and ordinary Portland cement concrete (OPC) concrete was also cast for reference.
