Analysis for Organic Components of a New Variety of Dry Mortar

Values of ignition loss and moisture content of a new variety of dry mortar were determined and the total content of its organic components was found by the difference of the above mentioned values and was amounting to (w) 14%. By applying methods of sieving, liquid extraction, gravimetry, FTIRS and pyrolysis-GC-MS, 2% of polypropylene fibre, 8% of sodium lignosulfonate, 3% of copolymer of ethylene and vinylacetate and 1% of organic auxilliaries (containing mainly varies alkanes and dioctylphthalate) were found in the organic components.
