Concrete Admixtures: Type_S
Concrete chemical admixture reference data — ASTM C494 Types A/B/C/D/E/F/G/S, ASTM C260 air-entraining, calcium nitrite corrosion inhibitors, VMA, SRA, and lithium nitrate ASR mitigation. Parameters include dosage range (mL/100 kg cement), water reduction (%), initial/final set time change (min), compressive strength effect at 1/7/28 days (%), slump increase (mm), air content change (%), and compatibility notes.
