In Vietnam although the demand for concrete Available online 31st Dec. is increasing in both civil and infrastructure construction such as rural 2020 concrete roads however the use of waste concrete aggregate to make Keywords concrete still has not been adequately studied. With the experimental test Concrete strength the authors have studied the change in the strength of concrete using large recycled aggregates thereby clarifying the possibility of using this Natural aggregate type of concrete in rural concrete road construction. The results show Recycled aggregate that if the amount of recycled aggregate to replace natural aggregate is Rural road below 30 the concrete strength achieved is slightly reduced compared Solid waste. 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.
