A Detailed Review of Equations for Estimating Elastic Modulus in Specialty Concretes
Publication: Journal of Materials in Civil Engineering
Volume 35, Issue 6
Abstract
Current code equations for estimating concrete elastic modulus are largely developed for normal strength concretes and based on general empirical relationships with concrete compressive strength. With the growing number of specialty concretes being used and investigated (ultrahigh-performance concretes, self-consolidating concretes, fiber-reinforced concretes, etc.) a detailed review of existing literature related and the applicability of existing elastic modulus estimation approaches may be helpful for both design engineers and researchers. This paper provides a comprehensive review of concrete elastic modulus estimations, including a review of the applicability of code-based calculations and alternative modulus equations developed from more recent experimental data. From the synthesized literature, it is concluded that design code elastic modulus estimations are inadequate, particularly for concrete mixtures containing fibers or large recycled-material volume replacements.
