“…Several fibre types in concrete manufacturing more excellent resistance to impact, abrasion and destruction. A higher length of steel or synthetic fibres can completely replace reinforcement or steel in certain situations [ 79 ]. Artificial and natural fibres give various concrete properties.…”

“…With superior durability, steel fibre is used in many construction applications. Steel fibre for concrete is a piece of the low-carbon steel wire with a diameter of 0.7–1.2 mm at a length of 25 to 60 mm [ 79 , 98 ]. In section, it can be round or triangular, and in configuration resemble an arc or bracket, or have a wavy shape.…”

“…When designing the FRFC composition, it needs to take into account the shape of the fine aggregates. The aggregates rounded shape reduces the likelihood of ordering of the fine aggregates and thereby increases the spreadability [ 79 ]. High values of slump lead to enhance in the average density of FC and the volume of materials used in production.…”

Fibre-Reinforced Foamed Concretes: A Review

et al. 2020

Foamed concrete (FC) is a high-quality building material with densities from 300 to 1850 kg/m3, which can have potential use in civil engineering, both as insulation from heat and sound, and for load-bearing structures. However, due to the nature of the cement material and its high porosity, FC is very weak in withstanding tensile loads; therefore, it often cracks in a plastic state, during shrinkage while drying, and also in a solid state. This paper is the first comprehensive review of the use of man-made and natural fibres to produce fibre-reinforced foamed concrete (FRFC). For this purpose, various foaming agents, fibres and other components that can serve as a basis for FRFC are reviewed and discussed in detail. Several factors have been found to affect the mechanical properties of FRFC, namely: fresh and hardened densities, particle size distribution, percentage of pozzolanic material used and volume of chemical foam agent. It was found that the rheological properties of the FRFC mix are influenced by the properties of both fibres and foam; therefore, it is necessary to apply an additional dosage of a foam agent to enhance the adhesion and cohesion between the foam agent and the cementitious filler in comparison with materials without fibres. Various types of fibres allow the reduction of by autogenous shrinkage a factor of 1.2–1.8 and drying shrinkage by a factor of 1.3–1.8. Incorporation of fibres leads to only a slight increase in the compressive strength of foamed concrete; however, it can significantly improve the flexural strength (up to 4 times), tensile strength (up to 3 times) and impact strength (up to 6 times). At the same time, the addition of fibres leads to practically no change in the heat and sound insulation characteristics of foamed concrete and this is basically depended on the type of fibres used such as Nylon and aramid fibres. Thus, FRFC having the presented set of properties has applications in various areas of construction, both in the construction of load-bearing and enclosing structures.

“…An effective method is the use for the materials of protective structures a fiber reinforced concrete, which potentially has a high impact resistance (Klyuev et al 2018;Lesovik et al 2018;Urkhanova et al 2018;Fediuk et al 2017Fediuk et al , 2018aFediuk et al , 2018bFediuk et al , 2019Abrishambaf 2017;Yoo 2016).The distribution of stresses in the concrete matrix, provided by the dispersion reinforcement leads, to a certain extent, to the growth of the whole complex of physical and mechanical properties and performance characteristics of the composite: both compressive and tensile strengths, crack resistance, impact endurance (Lesovik et al 2019;Ganesh et al 2018).…”

Composite binders were prepared as novel compositions, on the basis of which fiber reinforced self-compacting concretes (FRSCC) with high rheological, mechanical, dynamical, and impermeability behaviors are created. Rice husk ash, quartz sand, and limestone crushing waste within CEM I and different ratio of superplasticizer were investigated as components of composite binders. Central Composite Face Centered method was used to design the number of experiments and randomizations and then screened by Response Surface Methodology. The validity of models was projected by ANOVA. Replacement of cement by waste composite binders as a supplementary cementitious material has a positive effect on mechanical properties of FRSCC from 30% to around 35% of cement replacement. Adding the superplasticizer improved the performance of FRSCC in all aspects in the given range. Increasing the waste composite binders decreased the vapor permeability and effective diffusion coefficient of FRSCC by improving the hydration rate and decreasing the pores of the concrete matrix. Designed FRSCC has the potential to be used as a material for protective structures, because it is able to provide comprehensive protection against the dynamic effects and penetration of gases.

“…In the case of distributed fibers their distribution in the matrix is more uniformly and short fibers tend to take random orientation. However, even in these systems, fiber distribution is rarely completely uniform, and random fiber orientation is far from ideal [16][17][18][19][20][21][22][23].…”

The article deals with the application of combined reinforcement of fi-ne-grained concrete with steel wave and polypropylene fibers. High-density packaging of the mixture components was used to improve the strength and deformation characteristics. In order to reduce the cost of fibre concrete, composite binders were developed. Rational selection of filler and the use of a steel wave fiber gave the opportunity to get the fibre concrete with tensile compressive strength – 84.8 MPa, the tensile strength in bending – 19.8 MPa on technogenic sands of the Kursk Magnetic Anomaly. With combined reinforcement by steel and polypropylene fiber on technogenic sands of the Kursk magnetic anomaly fibre concrete with a tensile compressive strength – 82.8 MPa, in bending – 19.1 MPa was developed. With the same strength charac-teristics the developed mixture of fibre concrete based on combined re-inforcement due to reducing the amount of steel fiber at cost is lower by 25% compared to the composition on steel fiber and the same com-posite binder.
