Abstract:
The Tower A of Hongyun Building adopts raft foundation whose raft thickness is 4200 mm and the raft thickness outside the core tube is 3500mm. Considering such problems as anti-crack of large thick raft concrete, concrete curing, temperature monitoring and control, various measures are adopted on the aspects of concrete mixture proportion, quality of raw materials and concrete pouring temperature, to effectively prevent the generation of cracks.
