This document is a technical specification section (Section 701) from the South Carolina Department of Transportation (SCDOT) detailing standards for Portland cement and Portland cement concrete for structural construction projects. The document provides comprehensive guidelines for materials, mix design, construction methods, measuring, batching, and mixing of concrete, with specific requirements for cement types, water sources, aggregates, admixtures, and concrete classes ranging from 2500 to 5000.

The specification covers detailed technical requirements such as acceptable cement types (including Portland, blast-furnace slag, and limestone cement), water quality standards, aggregate characteristics, air entrainment specifications, and precise measurement tolerances for ingredients. The document includes a pricing structure for concrete by class and structure type (roadway, retaining walls, culverts), with payment calculated at 100% of the contract unit bid price upon completion of the initial surface finish. Price reductions are outlined for non-conforming concrete cylinders, with reductions ranging from 0% to 50% depending on the strength percentage achieved during testing.
