Additives and Fillers in Concrete

Additives and Fillers in Concrete

Additives and fillers are integral to enhancing the properties of concrete. Pozzolans and blast-furnace slag are additives or admixtures due to their reactions with calcium hydroxide released during cement hydration. Fillers, which are finely ground and similar in fineness to Portland cement, improve concrete attributes such as workability density, and reduce capillary bleeding or cracking. Some fillers possess hydraulic properties or participate in benign reactions within the cement paste.

Background:

Spontaneous spreading (SS) is a solution-processed fabrication method for organic photovoltaics (OPVs).
Current SS methods face challenges in achieving uniform film thickness and homogeneous morphology.
Developing efficient and reproducible OPV fabrication is crucial for renewable energy advancements.

Purpose of the Study:

Utilized phenanthrene (PAT) as a solid additive to regulate interfacial tension and drying time.
Fabricated uniform SS films on a water surface for OPV active layers.

Main Results:

Achieved uniform SS-film formation on the water surface.
Phenanthrene (PAT) additive improved molecular packing and phase-separated morphology.
The resulting OPV device demonstrated a champion power conversion efficiency of 16.4%.

Conclusions:

Introduced solid additives for the first time in SS-processed OPVs to control film-forming kinetics and morphology.
Demonstrated a versatile and simple approach for fabricating solution-processable and reproducible OPVs.
