AI Technical Summary
Existing technologies for preparing recycled concrete involve excessive water usage due to the pre-wetting of recycled aggregates, which affects the workability and strength of the concrete. Furthermore, excessive moisture interferes with the interaction between cement and aggregates, reducing the performance of the concrete.
The surface wetting water absorption rate method is adopted. By testing the difference in water absorption rate between the saturated surface dry state and the water-saturated state of the recycled aggregate, the surface wetting water consumption is calculated. This controls the water saturation of the recycled aggregate, avoids the impact of excessive water consumption on concrete performance, and improves compressive strength.
By rationally controlling the amount of water used, the mechanical properties of recycled concrete were improved, the compressive strength was enhanced, and the reliability and durability of the concrete were ensured.
