Cementing Sodium Chloride (NaCl) Accelerator Sodium chloride (NaCl), commonly known as salt, can be used in low concentrations to accelerate the setting of cement. In high concentrations, NaCl retards the setting of most cements, improves bonding of cement to shales, and minimizes damage in zones sensitive to freshwater.

Cementing
Sodium Chloride (NaCl)Accelerator
Sodium chloride (NaCl), commonly known as salt, can beused in low concentrations to accelerate the setting ofcement. In high concentrations, NaCl retards the setting ofmost cements, improves bonding of cement to shales, andminimizes damage in zones sensitive to freshwater. Adefoamer should be added to dry blends or to mixing waterto minimize foaming and air entrainment.
Features
Sodium chloride is a crystalline solid additive used in oilwellcementing applications. NaCl will not accelerate aseffectively as calcium chloride (CaCl2); however, NaCl maybe more readily available. NaCl salt is applicable over atemperature range of 50° to 500°F (10° to 260°C).
