Cement-Based Material - an overview | ScienceDirect Topics

D. Cusson, in Failure, Distress and Repair of Concrete Structures, 2009. Shrinkage strain (R < C) In cement-based materials, most of the shrinkage occurs when the cement paste dries out after setting and hardening.When shrinkage is restrained (Fig. 12.1b), permanent tensile stresses develop in the repair material and may cause cracking in the material itself, or delamination at the interface

Toward electrochemical synthesis of cement—An electrolyzer

Jun 09, 2020 · Fig. 1. Scheme for a low-emission, electrochemically based cement plant. An electrochemical decarbonation reactor powered by renewable electricity converts CaCO 3 to Ca(OH) 2 for use in cement synthesis. The decarbonation cell uses the pH gradient produced by neutral-water electrolysis to dissolve CaCO 3 at the acidic anode and precipitate Ca(OH) 2 where pH ≥ 12.5.
