THE RIGHT MIX FOR THE JOB Finding the perfect concrete mix is also vital to staying on schedule , as every other operation hinges on floors and load-bearing walls that have gained enough strength to keep moving forward .
“ We poured the structural deck typically at 2:00 a . m ., and by 3:00 p . m . that afternoon we poured columns and sheer walls — then by noon the next day we tensioned the post-tension slabs ,” says Duke . “ We had to have 3750 PSI on the concrete within 24-30 hours in order to make schedule . We also had to not just make the strength in the timeframe , but finish it .”
