Three new concrete mix designs have been developed for addition to Spec C-230 for use in the underpinning work. After discussing the pro-f portioning and qualification of mixes C-6C-H and E-5C-H (with superplas-ticizer) and mix E-5C (without superplasticizer), Dr. Iandsman concurred with CPCo's use of these for the underpinning work.
