Abstract - Water hyacinth is a freshwater weed that
regions. Water hyacinth is a fascinating aquatic plant. However, it's important to note that water hyacinth can be considered an invasive species in certain areas. Due to its fast growth rate, it can quickly cover water bodies, blocking sunlight and depleting oxygen levels, which can harm native plants and aquatic life. Despite its invasive nature, water hyacinth has some potential uses. It can be utilized in the field of construction.
grows in most frost-free regions of the world. Although it is often used as a water ornamental due to its beautiful flowers, it is considered to be one of the most problematic aquatic plants due to its negative impacts. In Assam, it is seen in abundance in almost every river body of the state. Concrete is a widely used artificial material made up of aggregates that are bonded together with a fluid cement. Once the cement solidifies, it forms a solid mass that resembles rock. It is the second most commonly used building material worldwide, following water. This project has been done to test the compressive, flexural, and split tensile strength of concrete by partially replacing cement with water hyacinth. Concrete was casted in the form of a beam, cube, and cylinder with varying percentages of water hyacinth ash (WHA), i.e. 0%, 5%, 10%, and 15% for 7, 14, and 28 days. The prepared samples were tested in a Universal Testing Machine(UTM) in the laboratory. The final results of the test were compared to those of conventional concrete. It was found that the highest strength was achieved at a 5% WHA replacement for M30 grade. After comparing the concrete and WHA replacement concrete, it was concluded that using a 5% ratio of WHA to replace cement in concrete is the optimal solution.
Concrete is a vital construction material known for its strength, durability and versatility. It is widely used in building foundations, floors, walls, highways, and bridges due to its reliability and cost-effectiveness in construction projects. As compared to the other materials in concrete, cement is the most costly material. Enormous amount of carbon dioxide are released during the cement manufacturing process which causes harm to the ecosystem in various ways. Studies and research projects have demonstrated that using locally accessible materials, like fly ash and egg shell etc. can replace cement in whole or in part, and this approach has been effective in satisfying the demand for concrete in construction projects. This research work studies the impact of water hyacinth ash in concrete mixes, which determines the optimal proportions that enhance the performance of concrete while reducing the environmental footprint.

1.1 Objective
1.INTRODUCTION The aquatic weed water hyacinth produces roughly two tons of material per acre and grows very quickly. Waterway destruction, fish habitat degradation that results in fish death, decreased oxygen dissolved in water, increased water loss from evapotranspiration, preventing mosquitoes from having a place to breed, and deterioration of swimming and fishing water quality are just a few of its detrimental effects on the environment. However, it harms the ecosystem in a number of ways. It can destroy waterways, harm fish by deteriorating their habitat and reducing the oxygen dissolved in water. India has implemented several strategies to manage and mitigate the spread of water hyacinth. These measures include physically removing the plant by hand, introducing insects that feed on the plant for biological control, and in some cases, using herbicides. Despite the progress made, water hyacinth remains a significant problem in many
