Estimation of concrete durability factor
"This study identifies the coarse aggregate properties important to concrete Durability Factor (AASHTO T 161) and explores different ways of testing those aggregate properties. Much has been done previously to estimate Durability Factor (and D-cracking resistance in the field), but few studies have been able to generate an adequate estimation or method for identifying good and poor performing aggregates. this study looks at a broad range of coarse aggregates properties and the study's purpose is to test those coarse aggregate properties in order to develop an equation for estimating Durability Factor for a diverse range of aggregates. Data from the study revealed a somewhat strong single-variable correlation between Durability Factor and: Sodium Sulfate Soundness, Adsorption, Vacuum Saturated Adsorption, and Nominal Maximum Aggregate Size. Tests that contributed to multi-variable regression equations were: Nominal Maximum Aggregate Size, Los Angeles Abrasion, Methylene Blue, Adsorption, and Sodium Sulfate Soundness. Ultimately, five different regression equations were developed for different purposes (ease, statistical power, etc.)"--Abstract, leaf iii.
