Sodium Thiocyanate is an organic sodium salt which is the monosodium salt of thiocyanic acid
Sodium thiocyanate (NaSCN) is used in concrete as a setting/strength accelerator, mainly in cold weather. Sodium Thiocyanate is an organic sodium salt which is the monosodium salt of thiocyanic acid. It contains a thiocyanate.It is an odorless white solid. Sodium thiocyanate is the chemical compound with the formula NaSCN.
Application
Sodium thiocyanate (NaSCN) is used in concrete as a setting/strength accelerator, mainly in cold weather.
Here are general industry guidelines (not a site-specific prescription):
Recommended Dosage (General)
-
0.2% – 1.0% by weight of cement
-
Typical effective range: 0.3% – 0.6%
Example
If cement = 100 kg
-
Minimum: 200 g (0.2 kg)
-
Common use: 300–600 g
-
Maximum (do not exceed): 1 kg
How to Use
-
Dissolve sodium thiocyanate completely in mixing water
-
Then add to the concrete mix
-
Ensure uniform mixing
Construction Industry : Sodium thiocyanate is used in the cement industry as an initial strengthening agent. The chemical enhances and strengthens bonding and acts as a grinding helper. Also, the use of sodium Thiocyanate prolongs the lifespan of cement. When preparing concrete, the chemical aidsin accelerating hardening. So, it’s a critical setting accelerator in concrete admixtures.
Dosage
Benefits
-
Faster initial and final setting
-
Improved early strength
-
Useful in cold climates or when early demoulding is required
Important Warnings
-
Do NOT overdose → can reduce long-term strength
-
Not recommended for RCC / prestressed concrete
(may increase corrosion risk of steel) -
Avoid combining with chloride-based accelerators
-
Always do a trial mix before site use
If you tell me:
-
PCC or RCC?
