RISUsing Supplementary Cementitious Materials to Mitigate Alkali-Silica Reaction in Concrete with Recycled-Concrete Aggregate
Publisher: ASCE
Abstract: Recycled concrete aggregate (RCA) is a key tool for improving sustainability in the construction and demolition industries. The use of RCA in new concrete is, in part, obstructed by the dearth of research available on the ...
Mesoscale Numerical Study on Time-Dependent Nonuniform Steel Corrosion–Induced Damage in Recycled Aggregate Concrete Systems
Publisher: ASCE
Abstract: This study investigates the chloride transport and resulting corrosion-induced damage to reinforced recycled aggregate concrete (RAC) using finite-element simulations. A two-dimensional five-phase mesoscale-level time-dependent ...
Generation and Numerical Analysis of Random Aggregate Structures in Recycled Concrete Aggregate Systems
Publisher: ASCE
Abstract: A computational modeling procedure for generating a random aggregate structure (RAS) for recycled concrete aggregate (RCA) materials is proposed in this paper. The two-dimensional aggregate generation was based on a convex ...
