| 摘要： | A test of concrete maturity and durability was conducted on a segment of US Route 33 during a road reconstruction project in Nelsonville, Ohio. Three different mixes were compared: Mix A had 30%blast furnace slag and used no.57 aggregate; Mix B had 30%blast furnace slag and used no.357 aggregate; and Mix C was a standard ODOT mix with no slag and no.57 aggregate. Sections of 1000 ft (305 m) were constructed using each mix. Half of each section was cured using wet burlap and the other half was cured using a spray-on membrane. In one slab in each half section, thermocouples were installed at the center and at one corner to monitor temperatures during curing. Small batches of each mix of concrete were also made in the laboratory and cured in a climate controlled chamber. |
