Temperature tracking system is designed to simulate the actual curing concrete structure temperature history experienced. By the test standard curing conditions at 20℃

50℃ constant temperature and variable temperature curing conditions

early age compressive strength of different strength levels fly ash concrete is measured. According to the compressive strength of concrete at early age of the two main factors: temperature and age

the calculation model of compressive strength of fly ash concrete is established and analyze the model parameters with introduction of equivalent age theory. The compressive strength of fly ash concrete structures is predicted by measuring temperature field with computational models. The results show that the compressive strength of fly ash concrete calculation model can accurately calculate the compressive strength of fly ash concrete structures

which can effectively guide the engineering application of fly ash concrete.
