FRACTURE ENERGY OF CONCRETE

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.

Concrete aggregates properties crushed by jaw and impact

Jan 01, 2019 Particle size distribution curves of recycled aggregates from building demolition concrete crushed by jaw and impact crushers. The jaw crusher produced 60% of coarse aggregates in weight, whereas the impact crusher produced 49% coarse aggregates. The proportion of particles finer than 0.15 mm is around 7–8% weight for both crushing mechanisms.
