| Abstract: | Based on sulfonating agent of sodium sulfite with seven crystal water,sodium sulfite,sodium bisulfite and sodium metabisulfite,selfheating productive technology was adopted to synthetize sulfonated acetone-formaldehyde superplasticizer and the method of single factor assessment was applied to study impact of the four kinds of sulfonating agent on the sulfonated acetone-formaldehyde superplasticizer.With the test results,the sulfonated acetone-formaldehyde synthetized by sodium sulfite with seven crystal water performs the better property on cement paste dispersibility and fluidity loss. |
