I tested my 4,000psi concrete mixed with 25% poly strength booster.
It did actually improve the damage resistance. Unlike regular concrete there was no chipping or spalling on the back side of the block after the first shot.
It seems like a pretty small improvement for what it would cost to go full scale. The cost of going full scale would add an additional $75 per yard to the cost of the concrete.
Bottom line, does 25% poly strength booster make your concrete stronger?
It would appear that it does.
Is it cost effective?
Probably not.
