MWCNTs dispersion adopting GA and its application towards copper tailings-based cementitious materials.

Hydrophobic carbon nanotubes are hardly to disperse in water and prone to agglomerate when poured with Copper Tailing-Based Cementitious Material (CTCM). Multi-walled carbon nanotubes (MWCNTs) + Arabic Gum (GA) dispersions were prepared by a novel method of synergistic optimization of concentration, controlling low-frequency ultrasonic time and setting the ambient temperature with non-toxic anionic surfactant GA as surfactant. The results of UV-Vis spectroscopy showed that the high stability MWCNTs + GA dispersion with low aggregation area (< 1.

High performance C-A-S-H seeds from fly ash-carbide slag for activating lithium slag towards a low carbon binder.

In this work, one-step synthesis of high-performance C-A-S-H (calcium alumina silicate hydrate) seeds from low-calcium fly ash (FA) and carbide slag (CS) by 7 days of mechanochemical mixing was proposed and used to activate lithium slag (LS) cement. The results showed that the seeding effect of C-A-S-H seeds was increased with the increasing Ca/Si (i.e.

Photocatalytic properties, mechanical strength and durability of TiO/cement composites prepared by a spraying method for removal of organic pollutants.

TiO/cement composites were prepared by a spraying method to degrade organic pollutants. After coated with waterproof liquid, pure cement pastes/mortars were sprayed with TiO suspensions with different TiO contents and spraying times. Photocatalytic properties, mechanical strength and durability were studied.
