Pine Needle Reinforcement in Concrete: A Sustainable Approach for Enhancing Mechanical Properties

Abstract

Abstract
 
This experimental study investigates the feasibility and potential benefits of incorporating pine needles as a sustainable alternative in concrete mixtures. Pine needles, abundantly available renewable resources, were considered for their potential as partial replacements for conventional aggregates or additives in concrete. The research aimed to assess the effects of varying pine needle proportions on the mechanical, thermal, and durability properties of concrete.The experimental procedure involved the preparation of concrete mixtures with different percentages of pine needle substitution. The properties evaluated included workability, compressive strength, tensile strength, durability against abrasion, water absorption, and shrinkage. Test specimens were subjected to comprehensive testing according to ASTM standards to ascertain the impact of pine needle incorporation on concrete characteristics. This paper discusses the findings, analyzes the implications of incorporating pine needles in concrete, and highlights the potential for sustainable construction practices. It further addresses the challenges faced and provides insights into the feasibility of using pine needles as an eco-friendly and effective additive in concrete production. The outcomes of this experimental investigation contribute to the on-going efforts towards more sustainable and innovative approaches in the construction industry.
