Concrete mixes

Post by MrFixIt1977 » Wed Jul 10, 2019 3:47 pm

I have access to loads of blasting abrasive “silica sand”. Can I use this as an aggregate, along with 1” clear gravel, in a concrete mix for a frost wall? Is it beneficial or detrimental to strength and durability over regular cement sand? I was thinking a 3:2:1 mix.

Thanks!

Blasting Abrasive ( silica sand ) should be ok for your mix most blasting sand is washed & grades Sand.
If the sieve size is with in standards for concrete mix requirement there is not a problem.
