The value of concrete in present society cannot be underestimated. We can see concrete structures everywhere, such as buildings, roads, bridges, and dams. There is no escaping the impact concrete makes on your everyday life. Concrete is a composite material which is made up of filler and a binder. Typical concrete is a mixture of fine aggregate sand, coarse aggregate rock, cement, and water. Cement and lime are usually used as binding materials, while the sand binder is mixed as fine aggregates and crushed stones, gravel, broken bricks clinker is employed as coarse aggregates. The concrete having cement, sand and coarse aggregates mix up in an appropriate percentage in addition to water is called cement concrete. In this kind of concrete, cement is used as a binding substance, sand as fine aggregates and gravel, crushed stones as coarse aggregates. An investigation relating to the use of byproducts to enhance the functions of concrete has been about for many years. In the recent years, the researchers have been made to use industry by products such as fly ash, silica fume, ground granulated blast furnace slag, glass cullet, etc., in concrete production and civil applications. The potential uses of industrial byproducts in concrete or as a partial aggregate substitution or as a partial cement substitution depending on their chemical composition and grain size, The utilization of these materials in concrete comes from the environmental constraints in the safe disposal of these products. Big interest is being focused on the environment and safeguarding of natural resources and recycling of waste materials. Various industries are producing a significant number of products which incorporate residues such as reclaimed aggregates, reclaimed asphalt pavement, foundry sand, copper slag, fly ash, glass cullet, polyethylene terephthalate, high density polyethylene HDPE, unplasticized polyvinyl chloride UPVC, plasticized polyvinyl chloride PPVC, low density polyethylene LDPE, polypropylene PP, polystyrene PS, expanded polystyrene UPS.

Temperature controlling is one of the most important process variables in the process control. In this paper describes the design and implementation of a Wireless Sensor Networks WSN based on XBee technology to monitor the history and current temperature information of remote locations. In this work, the microcontroller is used to compute and compare the value of current temperature and the set point values. LCD is used to display the result data. This result data is also sent to the microcontroller where the operator controls the whole process. Then, the signal passes to the relays to On Off case of the fan for maintaining the correct temperature.
