Analysis of Homogeneity Quality and Limit of Harmful Substances of Three Polycarboxylic Acid Superplasticizers
According to the standard method of GB/T 8077-2012,the homogeneity of standard typeand limit of harmful substances,early strength type and slow setting type polycarboxylic acid high performance water reducing agent was tested.The content of chloride ion was determined by ion chromatography,pH value was determined by pH meter,sodium sulfate content was determined by resistance high-temperature furnace,and residual formaldehyde content was determined by spectrophotometer.The content of released ammonia was determined with a basic burette,and the quality of polycarboxylic acid series high performance water reducing agent used in this area was analyzed.
