Synthesis and application of modified melamine superplasticizer

Modified melamine superplasticizer was synthesis by use of calcium of molasses and melamine plasticizer. FTIR infrared spectrometer was carried out for its structural analysis. Comparative tests of modified melamine superplasticizer, melamine plasticizer and FDN plasticizer on the water-reducing ratio, bleeding rate and fluidity of cement paste were investigated. Results showed that modified melamine superplasticizer has high water-reducing ratio. And cement paste with modified melamine superplasticizer has low bleeding rate and small loss of fluidity. The excellent adaptability between modified melamine superplasticizer and cement was indicated.
