used in concrete as per the requirement or demand of the work. Concrete is hard rock mass, found good in compression and weak in tension. It means concrete effectively manage the compressive loads on it but if we found tension forces on it, it generally loose its strength. In order to resist tension forces, we used Reinforcements i.e. steel bars of specified dia as per the work requirements. Production of cement and natural resources are used large amount for the production of concrete which impact our environment badly with the emission of harmful gases. Many researchers have found numerous ways to reduce such impacts to certain level. In our study, we used waste materials i.e. Saw Dust which partially replace the fine aggregates up-to certain content effectively. Along with this replacement, we used Jute fibers which helps to enhance the tension behaviour of the concrete up-to certain content. The usage of these waste products helps to manage the waste products along with the re-usage of such materials for better future products. The combination of these two materials has shown the good results on the strength properties of the mix. Further studies, can also made on such combinations to have indepth study.
1.INTRODUCTION
2. LITERATURE
With the development of our country, different industries of country inturns grow. Construction industry plays very important role in the infrastructure development of the country. Construction of buildings, bridges, flyovers, under water construction, etc. is familiar areas of this industry. From very start of the agies, construction takes places in different forms. And with these modern approaches, construction industry reaches at great heights. As construction grows very rapidly, the materials required to fulfil these consumptions also inneed largely. With the demand of such materials, production of these increasingly.
Sriram et al. (2021) investigated the use of granite powder and sawdus as partial replacements for cement and fine aggregate in concrete. They found that using granite powder at 10% of cement by weight was the most effective in increasing compressive and flexural strength. The 10% ratio of granite slurry and sawdus had great compressive strength, tensile strength, and flexure strength compared to 20% and 30% ratios. This suggests that locally available granite slurry and sawdus can be a good partial replacement for concrete, improving compressive, tensile, workability, and flexure characteristics while offsetting the overall cost of concrete.
Abstract – In our day to day life, the technology takes
place of almost everything. Technology and its applications should be like Go Green. Many researchers have found that the replacing the cement and other ingredients in the concrete would reduce the global warming impact. In our study, we use saw dust which would partially replace the sand content with the addition of jute fibers. The saw dust in replacement of sand i.e. fine aggregates were used as 0 to 50% with an uniform increment of 10% along with addition of jute fibers as 0 o 2% with the uniform increment of .5%. samples were prepared using these replacements accordingly and used to determine the strength parameters of the concrete mix. Fresh and hardened properties of the mix were find out. In the conclusion of this study, it is generally find that the optimum strength gain is achieved at certain percentage replacements and additons to enhance the concrete parameters. The overall results of the study were within the permissible limits.
We have already known to this fact, concrete is heterogeneous mixture of cement which acts as binder, fine aggregates, coarse aggregates and most important that is water. Concrete is defined as hard mass prepared by mixtures of above mentioned ingredients in finite proportion as required. Sometimes, admixtures will be added in it enhance its properties upto certain levels. Several admixtures are available in the market and will be

Jang et al. (2022) studied sustainable self-compacting concrete (SCC) properties using activated jute fibers and mineral waste powder. They found that mineral powders and jute fibers significantly improved SCC processability and mechanical properties. The combination of 0.1% jute fiber and 75mm zeolite powder provided the best mechanical properties.
