WK90388 - New Test Method for Standard Test Method for Determination of Microstructural Development of Mortar Cubes using the Bulk Electrical Resistivity Measurements

Work Item

ASTM WK90388

New Test Method for Standard Test Method for Determination of Microstructural Development of Mortar Cubes using the Bulk Electrical Resistivity Measurements

1. Scope

This test method covers the determination of the bulk electrical resistivity of hardened mortar cubes conditioned in lime-saturated water in order to provide a rapid indication of the development of microstructure, prior to testing for compressive strength.

Keywords

bulk resisitivity; mortar cubes; bulk resistivity index

Rationale

To provide a performance method for assessing an index of the resistance of different cementitious materials to ingress of aggressive fluids by the development of microstructure.
