Literature Survey on the Application of Wood Chips as Partial Substitution for Fine Aggregates in Concrete

The use of wood chips as a partial replacement for fine aggregates in concrete has gained attention due to its potential for enhancing sustainability and reducing waste. This literature survey examines various studies focused on incorporating wood chips into concrete mixtures, highlighting their effects on the mechanical properties, durability, and environmental impact of the concrete. Wood chips, derived from forestry residues or reclaimed wood, are explored for their feasibility as a substitute for traditional fine aggregates. Research indicates that while wood chips can improve the workability and thermal insulation properties of concrete, they often result in reduced compressive strength and increased water absorption compared to conventional mixes. The survey also reviews methods for mitigating these drawbacks, such as adjusting the water-cement ratio and using additives. Additionally, the environmental benefits of using recycled wood chips, including waste reduction and lower carbon footprint, are discussed. This overview aims to provide a comprehensive understanding of the current state of research and identify future directions for optimizing the use of wood chips in concrete applications.
