Cement and Concrete Composites, 2021 Abstract The ASTM C311 strength activity index test is a potentially flawed test because inert materials are known to be able to pass the test. The early age of testing, low fly ash replacement levels, variable water-to-cementitious materials ratio, and low strength limits all contribute to the inability of the test to successfully distinguish inert ...

Verification of specific grinding parameters and strength activity index of glass and clay brick
Pollack Periodica, 2015 The aim of this paper is to verify activity index (pozzolanic reactivity) of finegrained waste glass and clay brick. First part of this work consists from milling process with variation in milling parameters (time, grinding ratio) and determination (analysis) of the grain size distribution.

Strength Activity Index of Air Quenched Basic Oxygen Furnace Steel Slag
Journal of Iron and Steel Research International, 2015Abstract Air quenched basic oxygen furnace steel slag (BOF-SS) is processed at very high cooling rate, which is expected to have different cementitious properties from conventional slowly cooled BOF-SS. For this purpose, the strength activity indexes of air quenched and slowly cooled BOF-SS are investigated.

Interpreting the Strength Activity Index of Fly Ash with Machine Learning
Advances in Civil Engineering Materials, 2022ABSTRACT Fly ash from the coal combustion at electric plants is commonly used for partially replacing portland cement in concrete production. Because of the varying nature of the coal source and the different processing protocols, different fly ashes exhibit wide ranges of physical and chemical characteristics, resulting in distinct ...

Pozzolonic activity and strength activity index of bagasse ash and fly ash blended cement mortar
Materials Today: Proceedings, 2021Abstract Assessment of Pozzolonic activity of certain industrial waste is important due to an increasing need of cementitious material. This study was undertaken to widen the scope of using pozzolanic waste like fly ash and bagasse ash as a supplement to cement.
