Strength Tortuosity - Porosity Relation in Locally Types of Porous Media (Experimental Model)

Abstract

The experimental model of five types of porosity media (fine sand, gravel, sand, porcelanite and composed media) was conducted to determine the relationship between tortuosity and porosity. The red colour (Carmoisine E122) was used as a tracer. The results have good agreement with an empirical relation based on performing regression analysis on test result through the use of the trial version 9 of data Fit software of Oakdale Engineering computer programs. The proposed empirical equation was correlated as a function of three basic variables of media characteristics; porosity (n), shape factor (φ) and sphericity factor (P) by τ = 1 + C1 ∗ pφ(1 - nc2
