Computational Model of Fly Ash Concrete Compressive Strength Based on the Equivalent Age
摘要
Abstract
Temperature tracking system is designed to simulate the actual curing concrete structure tem-perature 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 estab-lished 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 mod -els.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 engineer-ing application of fly ash concrete .关键词
