The document summarizes an experimental investigation into the strength and analysis of basalt fibre concrete. Cubes and cylinders were cast using M25 grade concrete with local materials and varying proportions (0.5%, 1%, 1.5%) of basalt fibres to determine the optimum fibre ratio. Testing showed basalt fibre concrete had higher toughness and impact strength than plain concrete. Addition of basalt fibre changed the failure mode from brittle to ductile. Basalt fibre improved tensile strength and flexural behavior at higher fibre ratios. Compressive and split tensile testing of specimens indicated basalt fibre concrete strengths were higher than plain concrete, with 1.5% fibre ratio performing best.

Optimization of percentages of steel and glass fiber reinforced concreteeSAT Journals
Abstract Cementitious matrices are the fragile materials that possess a low tensile strength. The addition of fibers randomly distributed in these matrices improves their resistance to cracking, substantially. However, the incorporation of fibers into a plain concrete disrupts the granular skeleton and quickly causes problems of mixing as a result of the loss of mixture workability that will be translated into a difficult concrete casting in site. This study was concerned on the one hand with optimizing the fibers reinforced concrete mixes in the fresh state, and on the other hand with assessing the mechanical behaviour of this mixture in the hardened state, in order to establish a compromise between the two states . In this paper optimization of fibers by using different percentages in steel and glass fiber reinforced concrete of grade M 70 have been studied.

This document discusses different types of fiber reinforced concrete, including slurry infiltrated fiber concrete (SIFCON) and slurry infiltrated mat concrete (SIMCON). SIFCON involves pre-placing dry fibers in a mold and infiltrating them with cement slurry, allowing for higher fiber volumes between 5-30% compared to 1-2% in traditional fiber reinforced concrete. SIMCON uses continuous fiber mats reinforced with cement slurry. SIMCON provides inherent strength from the fiber mat configuration and utilizes fibers with higher aspect ratios.

The document discusses fibre reinforced concrete (FRC), which involves adding small fibres to concrete to improve its properties. Steel fibre reinforced concrete is the most common type of FRC. It improves tensile strength, flexural strength, impact resistance, ductility, and crack control compared to normal concrete.

While fibres improve properties, they are not a replacement for steel reinforcement in structural applications. FRC is useful as a supplementary material to improve performance.

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.

Studying the effects of Fibers and Mineral Admixtures on High Strength ConcreteAM Publications
This paper investigates on analyzing the effects of use of fibers and mineral admixtures in the mechanical
properties of high strength concrete. This study involves the use of different mineral admixtures like fly ash, ground
granulated blast furnace slag, silica fume along with steel fibers. It also includes determination of mix proportioning with
different mineral admixtures and steel fibers, determination of water binder ratio, determination of basic properties of

to explore the feasibility of arriving at an optimum mix using a combination of fibers with two or more mineral
admixtures, so as to increase the properties at minimum cost.
