Recently admixtures had made a major importance in the concrete manufacturing. These admixtures materials ranged from blood in the history to the recent retarding agents. In this paper analysis of properties of concrete using safety matches powder as admixture is studied and verified the strength of concrete and temperature emitted due to chemical reaction to the normal Portland cement. Using safety matches powder the temperature emitted due to exothermal reaction of concrete has reduced. This gives better results hence we can use this safety matches powder as an admixture where the reacting temperature and the emitting temperature place a crucial role in construction and maintenance.

Chemical admixtures are the ingredients in concrete other than Portland cement, water and aggregate those are added to mix immediately before or during mixing. These admixtures are primarily used to reduce the cost of concrete construction, to modify the properties of hardened concrete, to ensure the quality of concrete during mixing, transportation, placing curing and to overcome certain emergences during concrete operations. In this paper analysis of properties of concrete using potassium power as admixture is studied and verified the strength of concrete and temperature emitted due to chemical reaction to normal Portland cement. Using potassium powder the temperature emitted due to exothermal reaction of concrete has reduced. Thus gives better results hence we can use this potassium powder as an admixture where the temperature and the emitting temperatures place a crucial role in construction and maintenance.

Concrete admixture is added to enhance the properties of concrete to make its function as required. In this paper analysis of properties of concrete using of glass powder as admixture to concrete is studied and verified the strength of concrete and temperature emitted due to chemical reaction to the normal Portland cement. Using of glass powder as admixture the temperature emitted due to exothermal reaction of concrete has reduced. As glass has property of absorbing high temperature. This gives better results hence we can use this glass powder as an admixture. Where the reacting temperature and the emitting temperature place a crucial role in construction, and as glass powder is rigid and non-crystalloid solid this increase bond strength in concrete to increase its strength.

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.

Ingredients other than cement, water& aggregates that import a specific quality to either plastic(fresh)mix or the hardened concrete (ASTMC 496) is called concrete admixture. In this paper analysis of properties of concrete using banana peel as admixture is studied and verified the strength of concrete and temperature emitted due to chemical reaction to the normal Portland cement. As banana’s peel is rich in natural fiber and it is well known source of potassium. The flexural strength of concrete by using banana peel powder as admixture has increased, but considerable lesser compressive strength has increased. The percentage of transmission temperature and reduction time of temperature has decreased; hence it is clear that the exothermal reaction in concrete has been reduced by using dried banana peel powder as admixture.

Concrete Hardening

Due to the Portland cement chemical reaction, which always takes place in a hardening concrete, a certain amount of heat is released. This heat should be quantified, as it can harm or aid the concrete itself, depending on the concrete components, structure element, ambient and building site conditions. There are number of possible setups for the monitoring of heat of hydration, two of which have been applied in the case presented in this paper. Four concretes were monitored with the use of the two stated techniques for 24 hours. First technique used is thermo-vision camera which monitored the surface, and the second is thermosensor - used for monitoring of interior of fresh concrete hardening mass. The potential of the applied setup lays in the ease of installation, low price, and possibilities of mass application, which could substantially aid the monitoring and prevent concrete failure.

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.
