Ready Mix Design Specialist

The Concrete Mix Specialist is responsible for developing, optimizing, and troubleshooting concrete mix designs to ensure they meet project specifications, quality standards, and performance requirements. This role works closely with production teams, quality control, engineers, and customers to deliver consistent, high‑performance concrete across all applications.

• Develop and adjust concrete mix designs for various strengths, slumps, and performance requirements.
• Evaluate material properties (cement, aggregates, admixtures, SCMs) to ensure compatibility and consistency.
• Optimize mixes for cost efficiency without compromising performance.
• Provide submittals submittal packages for commercial and FDOT projects.

• Perform and oversee fresh and hardened concrete testing (slump, air, temperature, strength, density, cylinders, etc.).
• Troubleshoot mix performance issues such as low breaks, high water demand, segregation, or finishability problems.
• Maintain detailed records of mix performance, test results, and adjustments.

• Provide guidance to batch plant operators, dispatchers, and field personnel regarding mix performance and batching procedures.
• Assist customers, contractors, and inspectors with mix-related questions and performance expectations.
• Conduct field visits to monitor concrete placement, finishing, and curing practices.

• Ensure mixes comply with applicable standards (ASTM, ACI, DOT, project specifications).
• Maintain mix design submittals, batch tickets, material certifications, and plant quality documentation.
• Coordinate with suppliers to verify material properties and certifications.

• Identify opportunities to improve consistency, sustainability, workability, and production efficiency.
• Support training for plant and QC staff on proper sampling, testing, and batching procedures.
• Stay updated on new admixtures, materials, and industry technologies.

• Experience in concrete testing, production, or quality control.
• Strong understanding of concrete materials, mix designs, and proportioning.
• Familiarity with ASTM and ACI standards.
• Ability to analyze test data and diagnose mix-related issues.
• Excellent communication skills for interacting with plant personnel, contractors, and inspectors.
• Proficiency with batching software or QC software (COMMAND, Sysdyne, BCM, etc.) is a plus.

• ACI Level I or II Field Technician
• ACI Concrete Strength Testing Technician
• DOT certifications (state-specific)
• Ready-mix or precast production experience
• Background in materials engineering, construction technology, or related fields

• Ability to work in plant and field environments.
• Comfortable performing physical tasks such as sampling, testing, and climbing silos or stockpiles.
• Availability for early mornings, occasional nights, or weekends as needed for pours or troubleshooting.
• Ability to use power tools and the ability to lift up to 50 pounds with assistance.
