NCA (Non-Choride Accelerator) FAQ

Category: Set Accelerators

Q. What other effects will this product have on my concrete?

A. You may notice a slight increase in slump, since the product has some water reducing properties as well.

Q. Can I use less than one bag per yard?

A. Yes, you just need to experiment to get the right dosage for your particular needs.

Q. Can I use more than three bags per yard?

A. There's no point. More than 3 bags per yard will not give any faster acceleration.

Q. Will it change the final strength of my concrete?

A. No.

Q. Will NCA promote the corrosion of steel in concrete?

A. No, unlike the commonly-used calcium chloride, Fritz-Pak NCA will not promote corrosion or efflorescence.

Q. When I use powdered calcium chloride I notice that the water or the calcium chloride gets hot, but it does not happen with NCA. Why?

A. The heat released by calcium chloride when it dissolves solution is called heat of solution and is not related to the concrete setting up faster. The heat of solution of NCA is much less than the heat of solution of calcium chloride. That is why it is also a safer product.

Q. Will Fritz-Pak NCA have any affect on colored concrete?

A. No. NCA will not cause colors to segregate, the way calcium chloride tends to do in concrete containing integral color.
