Chemical admixtures are used in concrete for various purposes such as water reducing, plasticizing, air entraining, bonding, viscosity modifying, colouring, corrosion inhibiting, permeability reducing, accelerating or retarding the initial setting time, and shrinkage reducing. The use of chemical admixtures in concrete helps to improve workability of fresh concrete and durability properties of hardened concrete as well as reducing the total cost of concrete production. In this study, three different types of chemical raw materials (calcium nitrate, triethanolamine-TEA and calcium chloride) will be used in the production of chemical admixtures, which will be used in concrete with three-four different dosages. Day 1, 3 days, 7thday and 28thday, 56th day, 90th day compressive strengths of concrete will be determined and also fresh properties of concrete will be analysed. Effect of admixtures can reduce setting time when it is used along with different dosages. That’s why its effect will be checked with different dosages of different admixtures
