Abstract

In this paper, frost-resistance durability of high performance concrete (HPC) prepared with repeatedly recycled concrete aggregates was experimentally investigated by measuring mass, relative dynamic modulus of elasticity and compressive strength before and after freezing and thawing cycles. Three types of HPC were made with the 2nd generation recycled concrete aggregate (RCA) and natural aggregate concrete (NAC) were also casted as control concrete, with target value of compressive strength 40 MPa. The results demonstrate that apparent density of the 2nd generation RCA was above 2350 kg/m3 and water absorption was 8.7%. Scaling of the 2nd generation RAC (RRAC) was observed after 150 freezing and thawing cycles. The loss ratio of compressive strength of RRAC was below 20% when subjected to 300 freezing and thawing cycles. This study confirms the feasibility of preparing HPC with repeatedly recycled concrete aggregates based on frost durability and encourages facilitating the application of construction and demolition waste.
