Protection of concrete against physical, chemical and mechanical effects is directly associated with the properties of materials mixed into its compound and mixture. Among them, cement has a distinctive role. When cement is investigated both as a compound of the concrete and the paste, it is quite significant in terms of durability, service life and aesthetics. The greatest problem of cement usages is cracks negatively affecting both the subjective properties and the properties of aggregate used with it. The type and amount of cement used in a concrete, physical and chemical properties, hydration process, mixing method and technique, its relation with aggregate and water and additives depending on the time factor, have an effect both on functionality and visual performance. In this study, key words such as adherence, workability and cracking were taken into the center by dwelling on the cement subject, and the possible problems were offered a solution in terms of cause and effect relationship.
