MIT students fortify concrete by adding recycled plastic

Oct 25, 2017Concrete is, after water, the second most widely used material on the planet. The manufacturing of concrete generates about 4.5 percent of the world's human-induced carbon dioxide emissions. Replacing even a small portion of concrete with irradiated plastic could thus help reduce the cement Get price

TiO2 and ZnO powder affect photocatalytic activity of

Such additives ranged from 0 to 1.2wt.% in the cement paste, while the water/cement ratio (0.45) and superplasticiser (0.45 wt.%) remained invariable. Thus, pure blends and binary or ternary mixtures were studied. Nano-TiO 2 is the strongest influent factor to rheology Get price

Microstructural and photocatalytic characterization of

Abstract: A route for the in paste synthesis of TiO 2 loaded cement is described. TiO 2 sols are blended with fresh cement paste as an alternative process to add photocatalytic functionality to cement. The modification of cement paste structure after the addition of TiO 2 sols is analyzed by XRD, SEM and TGA. As a particular microstructural feature, TiO 2 containing calcium silicate hydrate (C Get price

Photocatalytic Purifiers: Are They Worth the Cost?

It is worth noting that the Molekule tech differs from other photocatalytic devices. The devices they produce use a specialized surface to improve the rate of reaction, which substantially increases the speed at which different agents can be destroyed. I'm lumping them in with photocatalytic purifiers, but there are key differences to recall. Get price

Concrete road lobby promotes TiO2 to eat fumes

A Study on Influence of Zinc Oxide in Cement Composite

In this research, the influence of zinc oxide (ZnO) on the phase compositions and crystalline structure and microstructure of cement composite was studied. ZnO powder (0.5-1 wt% of cement) was used as an additive material. The Portland cement and ZnO powder were blended and mixed with water at the ratio constant (W/C) of 0.4. Then, the paste was cast into the molded for 24 hours. Get price
