ABSTRACT:
The setting or hardening reaction of binders and cements of the types which are alkali-activated or acid-activated is controlled by forming a paste of the binder or cement and a salt which, under electrolysis forms the activating agent, placing the paste in a mold, providing two electrodes, one of which may be the mold, in contact with the paste, and passing an electric current between the electrodes to generate the activating agent by electrolysis.
