Geopolymer is a new trend in cement industry, traditional cement has prompted several problems related to health and environment due to cement dust and carbon dioxide. Geoplymer, however, has attenuated such problems due to the method of manufacturing and low emission of carbondioxide. This paper examines the ability to form geopolymer cement and the ability to use this cement in the formation of geopolymer concrete in the field. Various papers have been published with concern to the geopolymer cement set the curing in an oven is constraint to the geopolymer cement formation. During this paper are studied in air without any types of curing. Also the improvement of cement by meta koline as a source of aluminium and silica are studied. geopolymer cement based on the slag has been improved as it has been replaced with 10% metakoline. After optimizing the best mix of cement (slag and metakoline). The effect of geopolymer cement content is studied. Results have shown variation in compressive strength related directly to content of geoplymer strength. Water in geopolymer cement is not included in the reaction. So, throughout the paper the sea water is used as an alternative to fresh water. Results have shown an improvement in the compressive strength as compared to the presence of fresh water.
