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 ...

Establishing a reproducible protocol for measuring index active extension strength
Journal of Hand Surgery (European Volume), 2016The goal of this study was to establish a reproducible protocol to measure active extension strength in the index finger. The secondary objectives consisted in correlating the independent or associated index extension strength to the other fingers force of contraction of the extensor indicis propius with hand dominance. The population studied consisted

The rapid construction activity in Malaysia has increased the demand of concrete. One of the key ingredients in concrete is cement. The production of cement emits carbon dioxide (CO2) which is harmful to the environment. To overcome this issue, waste materials such as eggshell powder (ESP) and silica fume (SF) are incorporated in concrete as partial ...

Validating variation in radio-signal strength as an index of aquatic fauna activity
Australian Journal of Zoology, 2010Studying biological rhythms of activity and determining the external factors that influence behaviour of animals can be challenging in many aquatic habitats. We investigated the validity of using variations in radio-signal strength to quantify changes in activity of radio-tagged aquatic fauna on a small spatial scale under controlled conditions in the ...

Verification of specific grinding parameters and strength activity index of glass and clay brick
Pollack Periodica, 2015The 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.

Palm oil clinker powder (POCP) is an agro waste material that is often overlooked due to its low pozzolanic reactivity and contaminated with impurities and organic carbon. Therefore this study was proposed to enhance the pozzolanic reactivity of palm oil clinker powder through a chemical pre-treatment process.
