A study on behavior of reinforcement concrete beam using the recycled concrete

Abstract

The demand for concrete materials in construction becomes huge due to the development of the economy and urbanization in Vietnam. Recently, recycled aggregate concrete has been studied for partly replacing natural stone of concrete in the worldwide. It could save cost for land filling, and con-serve the national resources such as river sand and aggregate. Recycling concrete gives the benefit for environment. However, it may affect to the strength and performance of the construction containing the concrete waste. The paper is a discussion based on the experiments of reinforcement concrete beams with and without recycled concrete. Testing results are simulated by the ATENA program on exploring the behavior of beams. The analysis and experiment results show that replacing 20% of natural stone with re-cycled aggregate concrete does not affect both the bearing capacity and performance of beams.
