Selection of Concrete Mix Design Types for Petrochemical Structures

摘要

The selection of concrete mix design types affects the performance and constructability of petrochemical projects. There are many concrete mix design types that may be required for industrial projects including: controlled low-strength material, cellular concrete, self-consolidating concrete, high performance concrete, and chemical-resistant concrete. Each of these mix designs has unique properties and each has a specific use for petrochemical projects. Petrochemical structures have distinctive loading and durability demands due to their exposure to harmful chemicals and interaction with large mechanical equipment and piping systems. Revamp and retrofit projects should be done while the facility is in operation to minimize business interruption. If concrete work has to be done during a shutdown then the work must be done in a short duration. Specifying the proper mix design, therefore, is critical to the performance and constructability of a petrochemical structure.
