Useful:

• Chemical Classes: Metals -> Metals, Inorganic Compounds
• Canonical SMILES: C(=O)([O-])[O-].[Na+].[Na+]
• Inhalation Risk: A harmful concentration of airborne particles can be reached quickly , especially if powdered.
• Effects of Short Term Exposure: The substance is irritating to the eyes, skin and respiratory tract.
• Effects of Long Term Exposure: The substance may have effects on the respiratory tract. This may result in perforation of the nasal septum. Repeated or prolonged contact with skin may cause dermatitis.
• Chemical Properties and Applications in Cement Setting: Sodium carbonate is an organic sodium salt and a carbonate salt.; It is the disodium salt of carbonic acid with alkalinizing property.; Sodium carbonate, along with sodium phosphate, is commonly used for controlling cement setting and hardening.; It forms carbonic acid and sodium hydroxide when dissolved in water.; Sodium carbonate and sodium phosphate immediately precipitate in the presence of calcium ions, depositing on the surface of cement as one layer in cement paste.; Sodium carbonate accelerates cement hydration due to the interspace in the calcium carbonate-based layer facilitating ion dissolution.
• Applications in Cement Production: Sodium carbonate is used as an alternative to strong base activators in the preparation of one-part alkali-activated slag (AAS) cements.; It promotes cast-in-situ applications by simplifying the preparation process, leading to cost savings and reduced health and safety risks for handlers.; Na2CO3 can efficiently activate ground granulated blast furnace slag, resulting in compressive strengths of around 30鈥?40 MPa after 28 days of curing at ambient temperature.
• Applications in Food Preservation: Sodium carbonate has been shown to decrease the development of green mold (Penicillium digitatum) on lemons without negatively affecting their organoleptic characteristics.; Organic acids such as ascorbic, acetic, oxalic, tartaric, and lactic acid are commonly used in the food industry for their antimicrobial ability by lowering the pH inside and outside of microorganisms.
• Applications in Composite Materials: Sodium carbonate has been used as a treatment for natural coir fibers, enhancing composite properties such as tensile strength.; It removes amorphous compounds from fibers, improving composite properties, although it may reduce impact strength due to less fiber pull-out.; Sodium carbonate is compared to sodium hydroxide in terms of modifying fiber surfaces, with advantages including less degradation behavior towards fibers and eco-friendly nature, as well as shorter treatment times compared to sodium bicarbonate.
