A cement mortar composition and a manufacturing method thereof are provided to obtain strong construction material having deodorizing function which keeps warm evenly and effectively controls humidity and temperature. A cement mortar composition comprises 100kg of cement, 1kg of sepiolite, 1 kg of bio-stone, 1kg of perlite, 1kg of meteorite, 1kg of smectite and 100g of silver solution. The silver solution is made by electrolysis or by a process comprising steps of: adding 100g of 1N nitric acid to 100g of silver in a solubilization bath, followed by heating at 80deg.C; adding 500g of potassium carbonate while drying the mixture, and stirring the mixture for removing gas from the reaction concurrently with adding potassium carbonate until total amount of the potassium carbonate in the solution reaches 1,000g; adjusting pH of the mixture to 5; drying the mixture until small particles of silver salt appear; adding 500g of iron oxide to 200g of the silver salt and filtering the mixture; adding glacial acid and calcium carbonate powder to the mixture; and neutralizing the mixture until pH reaches 7. The manufacturing method of the cement mortar composition comprises steps of: grinding 1kg of sepiolite, 1kg of bio-stone, 1kg of perlite, 1kg of meteorite and 1kg of smectite in a ball mill until the particle size reaches 100 mesh or less; and mixing the prepared mixture with 100kg of cement, 100g of silver solution and 10kg of water while stirring the mixture.
