SNF-C Product Description
Basic Information
SNF-C, also named SNF18%&22% powder, is a mainstream High Range Water-Reducing Admixture and universal concrete water reducer in construction industry. SNF-C is divided into 18% and 22% powder grades by sodium sulfate content. Both grades of SNF18%&22% powder are standard naphthalene-based water reducing materials. As a core concrete water reducer, SNF-C fits most civil construction works. SNF18%&22% powder with steady quality acts as regular High Range Water-Reducing Admixture for stock preparation.
Product Overview
SNF-C and SNF18%&22% powder are produced via sulfonation, condensation and spray drying, classified as anionic High Range Water-Reducing Admixture and common concrete water reducer for infrastructure. SNF-C includes 18% low-sulfur high-performance powder and 22% cost-effective powder. SNF18%&22% powder serves key high-standard projects and ordinary residential buildings separately. SNF-C greatly improves concrete workability. As classic concrete water reducer, SNF18%&22% powder cuts mixing water effectively, being preferred High Range Water-Reducing Admixture for road, bridge and precast component projects.
Main Features
Superior water reduction: As professional High Range Water-Reducing Admixture, SNF-C and SNF18%&22% powder have stable water reducing rate, enhancing concrete density and compressive strength as reliable concrete water reducer.
Dual-grade targeted matching: 18% SNF-C resists crystallization and steel corrosion without pipe blockage under low temperature; 22% SNF-C features high cost performance, and SNF18%&22% powder satisfies both high-end and ordinary construction demands.
Wide cement compatibility: This concrete water reducer, SNF-C and SNF18%&22% powder, is compatible with Portland cement, fly ash cement and slag cement without negative reaction.
Cost saving & easy operation: Adding SNF-C High Range Water-Reducing Admixture reduces cement consumption. SNF18%&22% powder dissolves quickly and prevents concrete segregation and bleeding.
Stable storage performance: SNF-C powder keeps uniform texture against caking with long shelf life in dry storage. SNF18%&22% powder maintains stable physical and chemical indexes as concrete water reducer.
Application Method
Dosage standard: As general concrete water reducer, SNF-C and SNF18%&22% powder are dosed at 1.0%~2.5% of cement weight. Fine tune dosage for 18% SNF-C in premium projects, and adopt standard dosage for 22% SNF-C for optimal economy.
Feeding method: SNF-C High Range Water-Reducing Admixture can be added directly in dry powder form or dissolved in water before mixing. Delayed feeding maximizes dispersion effect of SNF18%&22% powder.
Pre-test adjustment: Conduct small batch test before formal use of SNF-C to confirm optimal dosage of SNF18%&22% powder due to raw material and temperature difference, securing stable performance of concrete water reducer.
Storage rule: Keep SNF-C in dry and ventilated warehouse to avoid damp caking which weakens High Range Water-Reducing Admixture function. Choose 18% SNF18%&22% powder preferentially for low-temperature construction.
