Concrete is among one of the principle materials that are used in civil engineering. In addition to numerous benefits, concrete suffers from disadvantages such as low tensile strength, low dynamic and flexural loading capacities and is also susceptible to formation and propagation of cracks. Fibrous technology eliminates or mitigates the weaknesses associated with conventional concrete. Extensive conducted researches in the field of fibrous technology in recent years have vividly demonstrated the technical merits of fibrous concretes. Addition of synthetic fibers in general and macro fibers in particular to concrete is on increase. The potential of fibrous concrete can be fully exhausted by close collaboration of civil and textile engineering disciplines. Thus this research tries to establish a sound relationship between the expectations of civil engineers and the requirements of fibrous concrete with various aspects of textile engineering. The corn stone of this project is thus based on defining the merits of s concretes reinforced with synthetic micro and macro fibers, optimization of fiber physical and mechanical properties in terms of polymer selection, selection of fiber production criteria, method of adding fibers to concrete and comparison of fibrous concrete with conventional type. Tailor-made fibers produced using principles of fiber engineering were used to produce concrete samples. Production of the required fibers is the unique advantage of this project over the previous ones in which readymade fibers had to be used. The various tailor-made staple fibers were added to concrete matrix at different fiber volume fraction. Experimentally obtained results were studied using statistical, analytical, numerical and the new focused ion beam (FIB) image processing methods. It was observed that tensile strength of the fibrous concrete is influenced by factors such as surface appearance, number and the mechanical properties of the added fibers. Results clearly point to the paramount influence of the surface characteristics of the fibers on enhancement of flexural strength of the fibrous concrete. Hydrophilicity of the polyester fibers tended to increase both tensile and flexural strength of the concrete samples. This due to the fact that fiber hydrophilicity in alkaline condition results in formation of dimple on the surface of the fibers as the result of which fiber to matrix adhesion is improved, despite the unavoidable reduction in mechanical properties of the fibers imposed by alkalinity environment of the concrete. It was found that the energy absorption capacity of the fibrous concrete is intensely increased. This was attributed to the fact that contact area between the added fibers and the concrete matrix increases due to reduction of the cross-section area of the fibers which in turn increases fiber specific surface area. Additionally it was found that as far as crack formation and propagation are concerned, sample that were reinforced with micro polyester fibers were superior to the samples that were reinforced with both micro and macro polypropylene fibers. Based on the simulation carried out using finite element method (FEM) it was concluded that experimental and model generated results are highly compatible
