Magnetic resonance imaging of ¹H, ²³Na, and ³⁵Cl penetration in Portland cement mortar

Cano, F.D.J. / Bremner, T.W. / McGregor, R.P. / Balcom, B.J.

The first magnetic resonance imaging profiles of chloride content in low- and high-permeability Portland cement mortar have been obtained using a novel material science imaging technique. The penetration of water as well as chloride and sodium ions, into mortar specimens was monitored for a period of 72 h. Marked differences in penetration depth were observed in low- and high-permeability mortar. These preliminary experiments show significant differences between the extent and nature in the penetration of chlorides compared to water and sodium.
