Study of the performance and microstructure of magnesium phosphate cement-based concrete
The magnesium phosphate cement-based concrete (MPC) stands out for its improved mechanical performance and unique microstructure. Understanding how curing age, fiber type, and fiber dosage influence these characteristics is essential for the development of sustainable and reliable construction materials. Research has shown that the addition of specific fibers can significantly optimize the compressive strength as well as the ductility of the concrete, achieving impressive strength values. This study aims to analyze these impacts and evaluate the results obtained during different curing phases.
Impact of curing age on MPC concrete
The variation of curing age plays a key role in the performance of MPC concrete. Studies have revealed that extending the curing time helps to enhance the mechanical properties of the concrete, particularly compressive strength and tensile strength. At specific ages, concrete can achieve exceptional performance. For instance, after 28 days, the compressive strength can exceed a critical threshold, thus ensuring the durability and longevity of structures. This phenomenon is largely attributed to the microstructural evolution that occurs during the curing phase.
Influence of fiber type and dosage
Research results indicate that the fiber type used in the mixture has a significant impact on the performance of MPC concrete. For example, steel fibers and basalt fibers are distinguished by their abilities to improve crack resistance. The addition of fibers in specific volumes has shown a notable improvement in mechanical characteristics, contributing to the cohesion of the material. Incorporation rates must be carefully evaluated to optimize benefits without compromising the workability of the mixture, which is crucial for the implementation of the concrete.
