Physical Origin of Temperature Induced Activation Energy Switching in Electrically Conductive Cement

Advanced Science, EarlyView.
The temperature‐induced Arrhenius activation energy switching phenomenon of electrical conduction in electrically conductive cement originates from structural degradation within the biphasic ionic‐electronic conduction architecture and shows percolation‐governed characteristics: pore network opening dominates the low‐percolation regime with downward ...

Morphology, mechanical properties, and biodegradability of all‐cellulose composite films from oil palm empty fruit bunch

SPE Polymers, 2020
Palm oil plantations are very important in that they supply vegetable oil globally. However, increased production of palm oil prompts the accumulation of large lignocelluloses residues in the form of oil palm empty fruit bunch (OPEFB).

Influence of size reduction of fly ash particles by grinding on the chemical properties of geopolymers [PDF]

, 2018
Chemical properties of geopolymers were evaluated from the reduction of fly ash particle size by grinding. X-ray diffraction determined that at early curing ages new crystalline phases appear in the matrix of the geopolymer and they remain for 28 days ...

Outline of a Washing Treatment to Improve Electric Arc Furnace Slag Environmental Behavior

steel research international, EarlyView.
This study evaluates a water‐washing treatment for electric arc furnace slag to reduce the leaching of hazardous elements (Cr, Ba, Mo, and V), enabling its reuse. The process effectively decreases leachate concentrations. Using the treated slag as a substitute aggregate in concrete reduces greenhouse gases emissions by 42.5% compared to landfilling ...

Experimental evaluation of reinforced concrete columns produced with natural perlite aggregates under cyclic loading

Structural Concrete, EarlyView.
Abstract A total of four reinforced concrete (RC) columns were tested to compare the structural capacities of RC columns produced by natural perlite aggregates and conventional concrete. The structural performance of the RC columns made from natural perlite aggregates was compared to conventional RC columns regarding the same concrete strength levels ...

Reviews on the Properties of Aggregates made with or without Geopolymerisation Method [PDF]

, 2013
Aggregates are popular for use in concrete and lightweight concrete applications. Recent research shows that the by-product materials such as fly ash can be used as raw material in producing aggregates and lightweight aggregates.
