Research on the Mechanical Properties of Recycled Aggregates from Alkali-Activated Slag Cement
The recycled aggregate is a recycled material,and compared with the natural aggregate,it has differences in mechanical properties.In order to further enhance the performance of aggregates,this paper uses water glass as an alkali activator to explore the mechanical properties of the recycled-aggregate cement-stabilized material prepared by slag cement and recycled aggregates,and analyzes the mechanism of the compressive strength,splitting strength and compressive rebound modulus of cement-stabilized materials under the action of alkali activation.Through experimental results,it can be seen that the cement content determines the strength of concrete to a large extent,and that the addition of alkali activators effectively improves the mechanical properties of concrete,with the most significant effect on the improvement of compressive strength.
