Abstract In today’s world the main emphasis is on green and sustainable development. River sand is one of the vital ingredient in the construction. Environmental concerns are being raised against uncontrolled extraction of river sand. But in presence of water it reacts with free lime and form hydrated products which helps in attaining good strength and also improving the durability. The arguments are mostly in regards to protect river beds against erosion and the importance having natural sand as a filter for ground water. So, prosopis juliflora wood powder is partially replaced with river sand. Keywords- Prosopis Juliflora, Natural Sand
I. INTRODUCTION Concrete is most widely used construction material in the world due to its ability to get cast in any form and shape. It also replaces old construction materials such as brick and stone masonry. The strength and durability of concrete can be changed by making appropriate changes in its ingredients like cementitious material, aggregate and water and by adding some special ingredients. Hence concrete is very well suitable for a wide range of applications. Prosopis juliflora wood powder is partially replaced 10%, 20% and 30% in place of natural sand. Prosopis juliflora (Seemai Karuvelam in Tamil) grows tremendously and spreads due to its mechanism to overcome adverse conditions of like drought and salt. This is facilitated by its high ‘proline’ content under stress conditions, which helps the plant to thrive where other species die. With deep penetrating roots, it can draw water from deeper layers. Though the species has played a role in changing land use and the livelihood security of huge populations of the world, due to poor management practices, it has colonized many important ecosystems, creating a negative pressure on biodiversity. Prosopis juliflora being invasive with negative impact to biodiversity and inhabitants, it has useful attributes also. This project involves the experimental investigation of strength properties of concrete by replacing PJWP with sand.
