Chemistry pros need help with formula

[Pugilist]

hello all
I am trying to make a block solid detergent that is a presoak. However the sodium carbonate component will swell after it hardens. It is blended with water. Does anyone know how to prevent this?

Thanks

Hello,
Here is my formula:
2 lbs water
Trisodium Phosphate .2173 lbs
Sodium tripoly phosphate heavey 2.173
Dense soda ash 4.21
Sodium sulfate anhydrous 3.17
Nonpheny ethoxylate (np9) .1086
Calsoft L-40 .3423

Blend in a disperser (1800 rpm) this will take on a wet cement consistency
pour into jar. Product will then harden. However after about 8 hrs the product will swell.
I may need to use light ash.
Any insight would prove useful
