A simple concrete mix design, natural materials

A great concrete mix design that we have used on many occasions in the Rio Grande Valley of Texas...

This mix design works great with a boom pump (L&G Pumping)

1/2" topsize aggregate, 1788#
sand, 1485#
Cement #1, 317#
Fly Ash, 106#

On site may add h2o to slump at 5-7"

Remember, mix designs vary by area and source of ingredients, so this should only be used as a guide.
