Abstract

The possibility of the use of three chemicals, namelya mix of mono and di ammonium phosphate (50:50), a mix of mono ammonium phosphate and BORAX (90:10), and a solution of 13% ammonium phosphate as fire retardants in materials used in the construction of GATHERING HALLS was studied. Wood (Picea) samples were prepared according to JISA, 322 Standard. To make wood samples FIRE RETARDING they were impregnated while employing HOT AND COLD BATH as ell as DIPPING methods. Fire retardation was achieved in STUFF and SPONGE while employing DIPPING method. Wood samples became the most FIRE RETARDING when treated with the mixture mono and di ammonium phosphate, (50:50) in cold and hot bath. These samples exhibited the most physical and mechanical strength when subjected to cmpression forces parallel to grain. Least volumetric contraction was observed in samples treated with AMMONIUM SULPHATE. STUFF impregnated by mono and di ammonium phosphate were more resistant to fire. Samples impregnated with AMMONIUM SULPHATE took the longest time to reach the fire point.The resulting Flame lasted least after torch removal from the sample in the case of SPONGEsimpregnated with mono and di ammonium phosphate.
