Which item is included in pre-construction compliance before concrete work?

• A. Mix design report
• B. Shrinkage test report
• C. Material compliance report
• D. All of these

Answer: (D)

In pre-construction for concrete, you submit submittals that establish how the concrete will perform before any work starts. The mix design report lays out the exact proportions, paste materials, aggregates, water-cement ratio, air content, and any admixtures, showing that the batch will reach the required strength and workability. Material compliance confirms that every component—cementitious materials, aggregates, admixtures, and water—meets specified standards and comes from approved sources. The shrinkage test report provides data on how the mix will shrink as it dries, which is essential for planning control joints, curing methods, and reinforcement to prevent cracking. Because each document covers a different aspect of meeting the project specs—strength and workability, material quality, and long-term dimensional behavior—all of these are included in pre-construction compliance before concrete work begins.
