Abstract:The influence and mechanism of porous structure on the deformation failure of cement sheaths under hydraulic pressure is still unclear. To solve this problem, a net slurry cement sheath and a liquid silicon cement sheath were prepared by using a cement material and a liquid silicon suspension. The distributions of the pore radius and spatial location were analyzed using computed tomography scanning and statistics to obtain their probability density distribution functions. Based on the distribution functions, t… Show more
“…2), 14,15 whereby the pores can have different sizes and shapes and affect the properties of the material. 16 The pore structure in concrete can be roughly divided into two types: capillary pores and gel pores. Capillary pores are small, interconnected cavities that transport liquids and gases in the concrete.…”
Typical coatings incorporate organic groups as carrier of hydrophobicity and polar groups at the solid interface, which are weak points in the interaction with water. In contrast, REOs are shielded from interactions with the environment.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
