Abstract:
The purpose of this investigation was to develop conductometric methods for several problems related to portland cement pastes and mortars. Problems investigated Include: (I) the setting phenomena during the first 3 hr; (2) the excess water tendency in sand-water mixtures; (3 ) measurement of internal stratification effects in cement pastes i.e., the relative vertical movement of constituents of a plastic mass as caused by capillary and gravitational forces, and (4) an attempted correlation of the electrical conductivity and the 28-day compressive strength of mortar mixes.
