Experimental Study on Durability Of Recycled Coarse Aggregate Concrete

摘要

The experiments on carbonation resistance、freezingthawing cycle、 impermeability and durability under multi-factors conditions of recycled aggregate concrete are researched, the carbonation speed、 freezing-thawing resistance and impermeability durability of the recycled aggregate concrete and the ordinary concrete are compared. The preliminary experimental research of freeze-thaw and antipermeability composite durability of recycled aggregate concrete has carried on, the results show that the superposition damage of recycled aggregate concrete is more sensitive, and the damage is greater.
