Urea
Urea is a chemical compound with the formula CO(NH₂)₂. It is a colorless, odorless, and highly soluble solid. It is also widely used in agriculture and industry. In fertilizers, it provides plants with nitrogen, an essential nutrient for their growth.
Automotive-grade urea, also known as diesel exhaust fluid (DEF), is a high-purity solution of 32.5% urea and 67.5% deionized water. It is primarily used in Selective Catalytic Reduction (SCR) systems in diesel vehicles, especially those with newer, more environmentally friendly engines.
Sodium Carbonate
Sodium carbonate is an inorganic compound with the chemical Formula Na2CO3 is a white, odorless, water soluble salt commonly known as soda ash or washing soda. Density is 2.54 gram/cm3
The glass industry is the largest consumer of sodium carbonate. Also used in soaps-detergents, printing-dyeing and paper-textile industries.
Sodium Hydroxide
Sodium hydroxide with the chemical formula Na+OH- also known as caustic soda and sodium hydrate, is an inorganic, highly alkaline and corrosive chemical compound.
It is widely used in making of wood pulp and paper, soap manufacturing, extracting alumina from bauxite, textile industry, in water treatment to pH control and removal of heavy metals.
Cement
Cement is a finely ground powder, is primarily made from limestone, clay, shells, and silica. When mixed with water, it undergoes a chemical reaction called hydration, which makes it harden and gain strength.
Cement is graded based on its compressive strength (measured in megapascals or MPa) at 28 days of curing. The grades are:
32.5 Grade Cement (general, construction),
42.5 Grade Cement (residential buildings),
52.5 Grade Cement (bridges, high-rise buildings)
