The Experimental Study of Early-Age Strength and Elastic Modulus of Concrete
Based on large numbers of experiment results, this paper carries out statistical analysis and proposes the probability distribution properties of the random process of strength and elastic modulus and their coefficient of variation, and develops a new prediction model of early-age strength and elastic modulus and their coefficient of variation respectively. The model can provide good prediction of the development of mechanical properties of concrete structures in aging, and it is important to evaluate the concrete structure safety and reliability in the construction period.
