Cement is the major ingredient of concrete having adhesive and cohesive properties and when it is combined with water, it forms a paste that is used for attaching and binding the other ingredients of concrete. The property of cement highly affects behavior of the concrete. When cement is stored, it loses its fineness property, which is important in hydration and strength development of concrete. In order to investigate the impact of moisture absorption of cement due to storage time, cements were collected from cement factory and stored for 1 month, 2 months and 3-month time. Then the materials were tested for cement and concrete properties. Laboratory results show that, fineness of the cement which was checked by sieve analysis and the percentage of the residue was 18% which is greater than 10% as recommended by IS standard; setting time of cement increases; slump results were collapse and compressive strength decrease by 22% after 3 months storage of cement. Finally, it was concluded that when the cement was stored for longer time, its properties affected due to moisture in the air.
