NOVELTY - Encapsulating inorganic phase change material particles, comprises (i) acidifying and alkalizing diatomite particles, (ii) absorbing phase change material into the treated diatomite, forming phase change material/diatomite complex, placing it on qualitative filter paper to obtain inorganic phase change material package, and (iii) coating the inorganic phase change material package using graphene oxide to obtain an inorganic phase change material package with film coating. USE - The method of encapsulating inorganic phase change material particles is useful for large-volume high-strength concrete (claimed). ADVANTAGE - The method solves the problem of the existing large-volume high-strength concrete in the application process, prone to thermal cracks, reducing the performance of components, safe bearing capacity, durability and service life; reduces overall temperature of the concrete, high compressive strength, no obvious cracks are generated, and well combined with the cement-stone interface.
