- Scope
- Compared with the high-performance water reducing agent in GB8076, the technical indicators of pressure bleeding rate were added to the tested concrete properties, the technical indicators of residual formaldehyde content were added to the general performance, and the chloride ion content, total alkali content, and sulfuric acid were added. Limit requirements for sodium content indicators; technical requirements for water reduction rate, air content, and compressive strength ratio have been improved; and low air entrainment type and high air entrainment type have been added to the classification. Compared with the high-performance water-reducing agents in TB/T3275 and TB10424, the water-reducing rate, bleeding rate ratio, pressure bleeding rate ratio, slump change over time in 1 hour, compressive strength ratio, chloride ions, Technical requirements for alkali content and sodium sulfate content; and added technical indicators for residual formaldehyde content.
