摘要

According to the technical requirements for concrete under normal condition and admixtures in large dam of Guizhou Silin Hydropower Station, several groups of admixtures and formula are designed and studied in combination with the climate of Silin Hydropower Station. The best formula is ultimately selected to meet the needs of construction. The results show that high efficiency water reducing agents with retardation setting are characterized by low dosage, high water-reducing rate and extra-long setting retarding time. The concrete doped with the products is characterized by good cohesive for its appearance and full wrapping. Its properties are able to fully meet the technical requirements between concrete under normal condition and admixtures Silin Hydropower.
