Title: Freeze-Thaw Durability Specification for Highway Concrete
Author: Ocampo, Joseph
Date Created: 2022
Subjects--Topical: Civil engineering
Description: The Super Air Meter (SAM) is a new method of testing that correlates to how well concrete can resist damage from freeze-thaw stresses. This test is a modified Type B pressure meter that undergoes a set of sequential pressure steps. The equilibrium...

Title: Hydration of Binary and Tertiary Fly ash and Quicklime Blended Cement Paste System
Author: Ojaruega, Akpovona
Date Created: 2018
Subjects--Topical: Civil engineering
Description: The hydration kinetics in blended cementitious systems with fly ash are quite different from those in conventional cementitious systems. The pozzolanic nature of fly ash not only reduces the rate of hydration in cement-fly ash blends, but also rea...
