Research on the possibility of applying concrete using recycled aggregates from waste concrete to build rural roads

Many researchers over the world have pointed out the great economic and environmental benefits of using recycled aggregate from waste concrete to make concrete. In Vietnam, although the demand for concrete is increasing in both civil and infrastructure construction such as rural concrete roads, however, the use of waste concrete aggregate to make concrete still has not been adequately studied. With the experimental test, the authors have studied the change in the strength of concrete using large recycled aggregates, thereby clarifying the possibility of using this type of concrete in rural concrete road construction. The results show that, if the amount of recycled aggregate to replace natural aggregate is below 30%, the concrete strength achieved is slightly reduced compared to the control concrete. As the amount of recycled aggregate increases, the strength of the concrete decreases significantly but still can meet the strength requirement of concrete in rural roads.
