Utilization of fly ash in massive concrete structures ? temperature evolution and multiscale modeling
Original language description
Massive concrete structures generally suffer from excessive hydration heat which results in formidable high temperatures. Fly ash presents a powerful method of reducing the amount of Portland clinker, resulting in lower temperatures and lower autogeneousshrinkage. In this paper, we demonstrate application of fly ash in Czech structures built from concretes C8/10 - C25/30 since 1960s up today. Temperature evolution is validated via multiscale model that further leads to a nomogram for general concrete massive structures. The nomogram predicts maximum concrete temperature depending on the type and the amount of a binder, added fly ash, member thickness, initial concrete temperature and ambient temperature. Performance of massive concrete structures containing fly ash demonstrates suitable utilization of fly ash in large quantities.
