Effect of FlyAsh Resource Reuse on Mechanical Properties of Concrete under Dual Carbon Target

Regarding the influence of different dosages of fly ash on the mechanical properties of concrete, in this paper, combined with the dual carbon goal, a new type of fly ash concrete was prepared by changing the dosage of fly ash, and three kinds of fly ash dosage were studied. The physicochemical properties (including XRD, SEM) and the effect on the compressive strength of concrete were comparatively studied. The results show that compared with ordinary concrete, the new fly ash concrete has obvious advantages in mechanical properties. It can not only meet the specific strength requirements, but also show higher strength than ordinary concrete under long-term standard curing. Therefore, the new type of fly ash concrete belongs to high-quality concrete, which is worthy of research and promotion.
