I have some gallon containers of AKKRO-7T Liquid Bonding Admixture. Asking $30 per gallon OBO. Here are a few things it does.
Increases flexural and tensile strength
Improves bond strength
Reduces shrinkage
Resists water penetration
Protects against freeze-thaw damage
Does not re-emulsify when exposed to water
