This study experimentally investigated the effects of adding polypropylene fibers on the properties of concrete. Concrete cubes and cylinders were made with polypropylene fiber contents ranging from 0% to 2% and tested at 7 and 28 days. The following conclusions were drawn:
1. Compressive and tensile strengths increased with higher polypropylene fiber content, with the maximum strengths achieved at 2% fiber content.
2. Split tensile strengths also increased with fiber content, improving by up to 22% with 2% polypropylene fibers compared to plain concrete.
3. The results indicate that polypropylene fibers can improve the mechanical properties of concrete, with strengths increasing with higher fiber dosage

Slurry infiltrated fibrous concrete (SIFCON) is a recently developed construction material using steel fibres and cement matrix. The matrix consists of cement slurry and infiltration is usually accomplished by gravity flow. SIFCON is the combination of cement, fibre and water with some admixtures. SIFCON has both high strength as well as large ductility. The properties of SIFCON are achieved through an optimized combination of matrix properties, fibre content and interface characteristics between fibre and matrix. This experiment is carried out to study the compressive strength, flexural strength of SIFCON. The results are then compared with that of Conventional Concrete and Fibre Reinforced Concrete.
Pervious concrete is a concrete composite material consisting of coarse
aggregate, cement and water. Because of the absence of fine aggregate in the mixture,
the aggregates are bonded together at its points of contact by cement paste, resulting
in a high percentage of interconnected voids that, when functioning correctly, permit
the rapid percolation of water through the concrete. In this work, polypropylene
monofilament and fibrillated fibres are selected as raw materials in three varying
percentage. 0.2% of fiber is added by the total volume of concrete and a new method
for determining the permeability of pervious concrete that provides better design
methodology is used. The experimental test values of permeability are discussed and
validated using Avizo software. The mix design is done for the water to binder ratio of
0.30. Coarse aggregate of 10 mm and 4.75 mm are selected in order to reduce the
void content as per the ACI 522R-06 codal provision. The addition of polypropylene
fibers shows enhancement in mechanical properties of the pervious concrete as
expected

A review of the effect of basalt fibre lengths and proportions on the mechani...eSAT Journals
Abstract
During the past few decades, the concrete construction field has seen a growing interest in the advantages that fibre reinforcement has to offer. Between the different types of fibres available, basalt fibre is considered a promising new material to use. It has extremely good strength characteristics and thermal resistance, high resistance to an alkaline environment, and is cheap product, making it an excellent material to reinforce concrete. In view of the significance of basalt fibres for concrete, and because different lengths and proportions of basalt fibres have an effect on the mechanical properties of concrete, it is proposed to review the effect of using different basalt fibre lengths and content on the mechanical properties of concrete. The mechanical properties of concrete reviewed are compressive strength, tensile strength, flexural strength, permeability, workability, and unit weight. This paper has for the first time reviewed the current literature related to the effect of using basalt fibres of different proportions on the mechanical properties of concrete, provided future researchers with the information and facts needed to compare their work, and identified the best basalt fibre length and content combination that demonstrates an improvement in the mechanical properties of concrete. From reviewing the literature, it was found that most authors agreed that the mechanical properties of concrete improved significantly when using basalt fibres with a length between 12mm and 24mm, and content between 0.1% - 0.5% by total volume. In this context, the length and content of basalt fibres in concrete becomes an important parameter for the mechanical properties of concrete.
Keywords: Basalt Fibres, Compressive Strength, Tensile Strength, Flexural Strength, Elastic Modulus, Workability, Permeability, Unit Weight.
In the world of high performances, we need a different type of concrete to fulfill our expectations. Here is a type of concrete which the world needs to complete their engineering work immaculately.
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
