EFFECT OF SHEEP WOOL FIBER ON FRESH AND HARDENED PROPERTIES OF FIBER REINFORC...IAEME Publication
Fiber reinforced cementitious composites are gaining attention in construction industry because of the high strength, ductility and energy absorption capacity. Concrete production is still under consideration to improve the sustainability and environmentally safety. Therefore, natural fiber reinforced concrete is the good alternative. Although sheep wools are producing a huge amount of waste, which can be utilized as building material in concrete if properly recycled. The addition of sheep wool in concrete mix was not very new, it has been used for insulation purposes. In this research the mechanical properties of sheep wool fiber reinforced concrete (SWFRC) were investigated. Total sixty cylindrical specimens and prisms were tested in this experiment to assess the fresh and hardened properties of SWFRC. The aim study was fulfilled by the results obtained from the split tensile test and flexural test. The weak tensile strength of concrete was enhanced by the addition of high tensile sheep wool and the cracks bridging effect of smooth and elastic fibers were worked to enhance the ductility and flexural capacity of concrete. Meanwhile, the compressive strength reduction due to addition of sheep wool in concrete can be minimized by proper treatment, which must need to investigate correspondingly
Use of Fiber is one of the vital and emerging trends in Construction Technology. Fiber can be considered as an alternative in the use of an air entraining agent providing sufficient freeze thaw protection and moreover as a reinforcing material. Fiber reinforced materials are composite materials that typically consist of strong fibers embedded in resin matrix. It is a composite obtained by adding a single type or a blend of fibers to the conventional concrete mix. The fibers provide strength and stiffness to the composite and generally carry most of the applied loads. The matrix acts to bond and protect the fibers and to provide for transfer of stress from fiber to fiber through shear stresses. Fibers can be in form of steel fibers, glass fibers, natural fibers, synthetic fibers, etc. The mechanism by which fibres produce resistance to freezing and thawing is that fibres introduction reduces water absorption of the concrete increasing penetration resistance to de-icing salts. Reduced water absorption is a function of the fibres to reduce plastic shrinkage cracking, reducing the ability of water to permeate into the bleed in a concrete. So this research paper describes experimental studies on the use of coconut fibre as enhancement of concrete.
Study on properties of sisal fiber reinforced concrete with different mix pro...eSAT Journals
Abstract
The present research was designed to check the workability and strength properties of sisal fiber reinforced concrete with different mix proportions and different percentage of fiber addition. The materials were chosen to improve the various strength properties of the structure to obtain sustainability and better quality structure. Short discrete vegetable fiber (sisal) was examined for its suitability for incorporation in cement concrete. The physical property of this fiber has shown no deterioration in a concrete medium. Fibers were brushed, lined up and cut to obtain 4cm length. Degree of workability of concrete mix with 0.2% super plasticizer and water cement ratio 0.45 had good workability with slump value 53mm and compaction factor 0.88, which is effective, was obtained. Materials were hand mixed with 0.5%, 1% and 1.5% addition of fiber in M20 and M25 mix design and casted in cubes and cylinders. The obtained specimens were subjected to tests aimed to check the compressive, tensile and flexural strength. An increase in compressive strength by 50.53% and tensile strength by 3.416% was observed for 1.5% addition of fiber in M20 mix design respectively. An increase in compressive strength by 52.51% and tensile strength by 3.904% was observed for 1.5% addition of fiber in M25 mix design respectively.

Effects of coconut fibers on the properties of concreteeSAT Journals
Abstract
The materials chosen for structural up gradation should not pollute the environment and endanger bioreserves. They should be accessible to the ordinary people and be low in monetary cost. Coconut fiber is an abundant, versatile, renewable, cheap, lignocellulosic fiber and more resistant to thermal conductivity. The aim of investigation is to study the possibilities to use the coconut fiber in addition to the other constituents of concrete and to study the strength properties. A literature survey was carried out, which indicates that the detailed investigation of coconut fiber concrete is necessary. In the present study the deformation properties of concrete beams with fibers under static loading condition and the behavior of structural components in terms of compressive strength for plain concrete(PC) and coconut fiber reinforced concrete(CFRC) has been studied.
The testing of various material constituents of concrete was carried out according to the Indian Standard specifications. To identify the effects on workability and mechanical strength properties due to the addition of these coconut fibres, workability tests such slump, vee – bee, compaction factor test, Flow table tests, and the mechanical strength tests on standard specimens such as compressive strength, split tensile strength, modulus of rupture were conducted on the different aspect ratio. The standard cubes, cylinders and beams for conventional concrete and coconut fiber reinforced concrete were prepared and tested under compression testing machine and flexure testing machine respectively. The suitability of CFRC as a structural material is studied, in comparison with conventional concrete.

Study of Flexural Strength and Flexural Modulus of Reinforced Concrete Beams ...Premier Publishers
This study was carried out to investigate the effects of raffia palm fibre on some mechanical behaviour (flexural strength, flexural modulus, water absorption rate and density) of concrete. A concrete mix ratio of 1:2:4 was used for the concrete beams production, while a water to cement ratio (w/c) of 0.5 was adopted. In the study, three different fibre lengths (10, 20 and 30 mm) and three different fibre content (volume) by mass of fine aggregate (1, 2 and 3%) were considered. According to the results of the preliminary test carried out on the fine aggregate, it had a silt content of 1.6%, a moisture content of 8.3%, and a specific gravity of 2.95. Flexural properties of the beams were tested in accordance with ASTM recommended procedures after 28 curing days. Results obtained showed that fibre volume had significant (p ≤0.05) effect on the flexural strength and flexural modulus of the beams. The flexural strength and flexural modulus decreased linearly as the fibre volume increased from 0% to 3%. According to the results, the fibre reinforced beams were more ductile, when compared to the unreinforced concrete beams. In addition, the densities of the beams decreased with increase in the fibre volume; while their water absorption rate increased with increase in the fibre volume. The low densities and brittleness of the reinforced beams (at low volume) made them good building materials, especially when heavy weight beams are a problem, provided the beams are not exposed to high moisture levels.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.
