A byproduct of ongoing regeneration projects, recycled aggregates are typically materials that would have previously gone to landfill but that are now processed to be reused as an alternative to traditional aggregates. Why use recycled aggregates? eco friendly and cost effective by reducing the impact on the environment, reducing materials sent to landfill [.]

This paper presents the experimental results of pullout tests conducted to determine the bond characteristics of concrete using aggregates made from the recycling of concrete waste from demolished buildings. Factors such as water–cement ratio (0·5, 0·4 and 0·3), bar diameter (ø = 10, 12 and 16 mm), embedment length (2·5ø, 5ø and full depth of specimen) are considered.
