Abstract:
During construction of Houston’s new $300 million 69th St. complex wastewater and sludge treatment plant, the contractors experienced extended periods of 100 F (38 C) heat that necessitated extra care and measures during the placing of shrinkage-compensating Type K concrete. A gravel aggregate was used to reduce water absorption, large quantities of ice were used to control concrete temperature, high slumps were mixed at the batch plant to get the required slump at the site, and a communication system was set up to monitor conditions of the concrete as it arrived at the site and radio mix adjustments to the batch plant as required.
