摘要：
In order to study the frost-resistant durability of recycled concrete, This test of freezing and thawing cycle were conducted to normal concrete specimens, recycled concrete specimens and include 2% LJ115 liquid anti-freezing mixture recycled concrete specimens respectively by quickly freezing method at +/- 20 +/- 2 degrees C. On the basis of this,to the four kinds of specimens, analyse the mass loss rate and the dynamic modulus of elasticity. The result indicates that the frost-resistant durability of include antifreeze recycled concrete had improved greatly, even more than the normal concrete.
