Novel micro-encapsulated phase change materials with low melting point slurry: Characterization and cementing application
The lower heat of hydration and temperature rise of slurry were required for hydrates formation cementing, the traditional experimental methods often result in a great reducing in the application performances. Therefore, the organic and inorganic composites were applied to develop a novel cement slu...
