nitrateAmmonium Nitrate How they are manufactured? Ammonium nitrate is made commercially by passing ammonia gas (NH3) and a water solution of nitric acid (HNO3) through a pipe. The ammonia combines with the nitric acid to form ammonium nitrate. The formula for this reaction can be written as NH3 + HNO3 → NH4NO3. Large amounts of heat are released during the reaction‚ so the pipe and supporting equipment must be very strong. The solution of ammonium nitrate in water is allowed to evaporate‚ leaving

developers say that concrete is safer. 2-foot thickness of concrete provides an outstanding resistance of fire. Moreover‚ it can resist very high temperatures for long intervals of time without any loss in the structural integrity. Concrete requires fireproofing treatment in order to meet fire codes. Additionally‚ Reinforced concrete can resist winds with speed 200mph and more. Also it showed an outstanding behavior in earthquakes.
