Mechanized sand is gradually replacing natural sand in engineering construction due to its abundant resource reserves, but its production process is prone to producing excessive mud powder, which has a negative impact on the mechanical properties of concrete.
Existing research has mostly focused on the optimization of curing for low clay content mechanism sand concrete.
However, there is still a lack of research on the long-term strength development of concrete under different curing systems for high clay content conditions, and the coupling mechanism between curing methods and clay powder deterioration effects is not yet clear.
The curing conditions directly determine the hydration process of cement and the compactness of the internal structure, which is an important way to improve the performance of high clay content mechanism sand concrete.
This article systematically analyzes the influence of curing methods on the strength of concrete at different ages by setting up multiple sets of curing control experiments, revealing the internal mechanism of action, in order to provide theoretical basis for the selection of curing schemes and performance control of high clay content mechanism sand concrete engineering.
