粉煤灰在再生混凝土中的应用与研究

 系统研究了在再生粗骨料取代率为50%的情况下，采用粉煤灰等量取代水泥、超量取代水泥和粉煤灰代砂法3种情况来配制再生混凝土。通过实验，分别测定了再生混凝土的强度及和易性，最终得出在不同取代情况下，粉煤灰的不同取代量对再生混凝土强度以及和易性的影响，为粉煤灰在再生混凝土中的应用提供理论依据。

Research and Application of Fly Ash in Recycled Concrete

In this paper，it was introduced that the case that under 50% replacement of recycled coarse aggregate（RCA），the recycled concrete was prepared by 3 methods of fly ash equally replacing cement，fly ash excessively replacing cement and fly ash replacing sand.The strength of the recycled aggregate concrete and mixtures peaceability were test. Eventually it is concluded that the strength and mixtures peaceability of recycled concrete were affected by different circumstance under the different amount of fly ash，and a theoretical basis in the impact of fly ash in the application of recycled concrete is provided.
