Thesis (M. Eng.)--Massachusetts Institute of Technology, Dept. of Civil and Environmental Engineering, 2013.Cataloged from PDF version of thesis.Includes bibliographical references (p. 37-38).Since its development in the early 1970's, researchers have continued to push the limits of concrete mixtures through the creation of ultra-high performance concretes. The use of this class of materials has allowed designers to build lighter and stronger structures, and in some cases has allowed the construction of concrete members that do not require reinforcement. However, as designers consider integrating and adapting these high performance materials into their structures, they should be aware of the diminishing returns on the modulus of elasticity when increasing the compressive strength of the mixture. While these UHPC mixtures have many desirable qualities in relation to strength, durability, and longevity, designers should still be aware of the pitfalls that result in the relationship between the compressive strength and modulus of elasticity.by Daniel Scott Abrams.M.Eng
