English Abstract

This paper investigates the application of two probe electric resistivity method as an early age concrete durability indicator and its relationship with the most commonly used durability indicator, compressive strength.

The experiments were conducted under laboratory environment on a particular cement paste at the same water cement ratio and sand cement ratio.

Temperature and curing conditions were kept the same.

The results show that both the resistivity and compressive strength increases during the early age of hydration.

The time against resistivity graph follows a logarithmic trend for this particular cement mix whereas the relationship between compressive strength and time is linear.

The relationship between these two properties follows an almost linear increasing trend.

A simplified linear equation has been proposed for predicting the strength gaining of mortars for this cement mix using its early age resistivity values.
