FRACTURE ENERGY OF CONCRETE By Zdenek P. Bazant,l Fellow, ASCE ABSTRACT: The role that plastic-frictional energy dissipation in the fracture process zone plays in the work of-fracture method for measuring the fracture energy of concrete or other quasibrittle materials is analyzed, and a possible improvement of this method is proposed.

The 28-day period is an arbitrary specimen age – though chosen for many good reasons – for testing the compressive strength of concrete. Specification writing authorities chose 28 days as the standard specimen age to establish consistency for testing procedures throughout the industry (1). Such an arbitrary time frame, however, is not

This paper presents the results of a recent investigation on the performance of four recycled concrete aggregates (RCAs). The materials, obtained by crushing concrete with compressive strength ranging from 15 MPa to 75 MPa, were reconstituted to satisfy the grading requirements for a subbase material.
