PERFORMANCE CONCRETE

The conventional concrete mix, called Performance Concrete, is proportioned similarly to the “mix stack” shown below. These are produced exclusively by our business unit Performance Precast Company.

“Performance Concrete” is an ‘optimized mix’ design with precisely controlled gradation.  This results in concrete that is both sustainable and resilient.  Strengths range from 4000-8000psi.

Substituting 50% slag cement for Portland cement reduces greenhouse gas emissions by more than 40%
