Abstract

In order to study the effects of fly ash and mineral powder on the properties of recycled concrete,the effects of different mixtures of fly ash and mineral powder on the compressive strength,flexural strength,carbonization resistance and sulfate attack resistance of recycled con-crete were studied experimentally.The results show that the performance of recycled concrete can be significantly improved by adding fly ash and mineral powder,and the optimal mixture content of fly ash and mineral powder is 20%.At 90 days,the compressive strength and flexural strength of the concrete are increased by 2.96%and 2.31%compared with ordinary concrete,respectively.The strength reduction coefficient of 20%fly-ash and mineral powder mixed recycled concrete is the best,which is 11.79%.It shows that the addition of fly ash and mineral powder can improve the durability of recycled concrete.
