A Review on Introducing Fibers in Concrete for Blocks, Pavers and Kerbstone

Abstract:

At present, concrete blocks serve as the primary construction material in civil engineering due to their convenient material selection and impressive compressive strength. However, their limitations in terms of low tensile strength, poor toughness, and susceptibility to cracking hinder their progress. To enhance the flexibility and resilience of concrete, incorporating fibers is a viable method to develop a composite material. Concrete blocks, pavers, and kerbstones are widely using in construction applications. However, this is susceptible to cracking, especially under heavy loads or in harsh environmental conditions. Pine needles is a promising new material for reinforcing concrete. This is strong, durable, and sustainable. Pine needle is a promising material for reinforcing concrete blocks, pavers, and kerbstones. It has been shown to enhance a wide range of concrete valuables, containing tensile strength compressive strength, flexural strength, toughness indices, and energy absorption. This makes it a better choice than other reinforcement materials, such as millet husk ash, PET bottle, sheep wool, and coconut-fiber rope, which have only been shown to improve certain properties. Based on the literature review, wheat straw should be the first choice for reinforcing concrete due to its superior performance. Fibers, following certain treatment or recycling processes, [specified material] has been documented for its utilization in various forms as construction materials. Consequently, the objective of this literature review is to provide a comprehensive overview of the potential of waste fibers in the production of concrete blocks, pavers, and kerbstones. This entails a specific focus on scholarly articles published within the last decade in highly regarded journals.
