Cement-based materials used at radioactive waste disposal sites are required to possess long-term stability. However, when these materials come in contact with groundwater, calcium leaching from the solid occurs, and the material becomes porous. The

Concentration and Molecular Weight of Superplasticizer Contained in Pore Solution Extracted from Hardened Cement Pastes

Autor: Masahito Shibata, Morihiro Mihara, Hideki Fujita, Kazuko Haga

Publikováno v: Journal of Advanced Concrete Technology. 6:389-395

There are concerns about the possible increase in the solubility of radionuclides due to the presence of superplasticizers proposed to be added to cementitious materials in a radioactive waste repository. The concentration and molecular weight of a p
