Every recommendation starts with your cement, aggregate, temperature, target slump and strength. Standard grades can be adjusted for project-specific requirements.
Water-Reducing Type
SNF naphthalene-based superplasticizer is a concrete water-reducing admixture in the Qiandao New Materials range. The brochure presents two SNF options: FDN-I and FDN-II (slow-setting). Their dosage ranges, setting behavior, air-content limits, strength ratios, and performance descriptions differ, so the selected grade should be tested with the intended cementitious materials and construction conditions.

Water-Reducing Type
PCE polycarboxylate superplasticizer is a concrete water-reducing admixture in the Qiandao New Materials range. The brochure presents two PCE options: SY-PA and an ultra-early-strength, high-dispersion grade. Their published dosage guidance, water-reduction values, strength ratios, and performance descriptions differ, so select and trial the grade for the intended cementitious system and construction conditions.
