As building industry evolves, stronger more durable and increasingly specialized products are in demand fiber reinforcement took an important role, fiber reinforcement to meet requirement changed with material composition and patterns such as fiber mesh, micro fibers, macro fibers, etc. In this paper analysis of properties of concrete using nylon fiber as fibre reinforcement admixture is studied and verified the strength of concrete to the normal Portland cement. Using nylon fiber the compressive strength and flexural of concrete has increased to very limited extend. As the friction between concrete and nylon fiber is very less, so it gives very less interlocking between concrete.

The tremendous increment of demand on concrete made admixture one of major component. As admixtures help in enhancement of concrete physical and chemical admixture. In this paper analysis of sea shells as chemical admixture is studied and verified the strength of concrete and temperature emitted due to chemical reaction to the normal Portland cement. As sea shells contain calcium carbonate, CaCo3 as major composition, as calcium is one major component that helps in densifying and hardening of bones in all living things. The flexural and compressive strength has gradually increased; the transmission temperature and reduction time of exothermal reaction has reduced. Hence seashell acts as great admixture.

Aggregate in concrete acts as structural filler, these place a crucial than simple statement implies it is the material that the cement paste coats and blind together. Now a day’s using river sand is prohibited by government, as these cause soil erosion. In this paper analysis of properties of concrete using manufacture sand as course aggregate is studied and verified the strength of concrete and temperature emitted due to chemical reaction to the normal Portland cement. Using manufacture sand as course aggregate the temperature emitted due to exothermal reaction of concrete has reduced. Although the compressive strength of the concrete has reduced compared to normal concrete where no admixtures were used to enhance the properties of concrete.
