Abstract
Many concrete constructions have reached the end of their service life or have been damaged by natural disasters and will create a great amount of waste concrete at a future date. At the same time, societies around the world continue to consume a large amount of natural aggregate. To reduce the environmental impact of this impending force, a need has arisen to develop a use for recycled aggregate (RA) and to develop a recycled aggregate concrete (RAC) with enhanced performance. Recycled aggregates from waste concrete have been used as filler in road construction and in low-level applications due to material deficiencies such as large water absorption capacity and irregular shapes, which influence the workability of concrete. This study evaluates the performance of RAC with atomic polymer technology (APT). It considers different degrees of APT and performs a series of concrete shrinkage, mechanical property, and dynamic tests. A wave propagation test, also performed, uses embedded smart piezoelectric sensors and actuators. The outcomes of this study identify the effect of APT on RAC properties, promote the widespread application of recycled concrete in engineering, improve the sustainability of RAC structures, and provide viable long-term health monitoring techniques for RAC structures.
