Paper Title:
Experimental Study on Frost Resistance Durability of Concrete with Intensified Recycled Aggregates
  Abstract

In order to study high performance recycled concrete, the recycled concrete is prepared through the double admixing technology, i.e. mixing of high-quality mineral admixture and high-efficient water reducer. It is modified with the recycled aggregates soaked in and intensified by chemical grouts. The mass loss rate and relative dynamic elastic modulus of the recycled concrete are measured through fast freeze-thaw test, and a model for predicting the life of the recycled concrete under freeze-thaw conditions is built. The experiment results show that it is an efficient way to intensify recycled aggregates through being soaked in chemical grouts. The recycled concrete prepared with recycled aggregates intensified by chemical grouts, high-quality mineral admixture and the high-efficient water reducer feature favorable frost-resistance.
