Low-Carbon and Fundamental Properties of Eco-Efficient Mortar with Recycled Powders.

Using recycled powders from solid waste is accepted as an effective strategy to realize the sustainable development of the construction industry. In our study, the cement was substituted by two kinds of recycled powders, i.e.

Preparation and Characterization of Zeolite/TiO₂ Cement-Based Composites with Excellent Photocatalytic Performance.

A zeolite/TiO₂ composite (ZTC) was applied to prepare a high-quality photocatalytic cement-based material (PCM). The acetone degradation experiment and micro measurements including XRD(X-Ray Diffractometer), SEM-EDS(Scanning Electron Microscope-Energy Dispersive Spectrometer), BET(BET Specific Surface Area Tester), FTIR(Fourier Transform Infrared Spectrometer) were conducted to characterize the photocatalytic efficiency and physicochemical properties of PCM, respectively. Results show that TiO₂ particles disperse on the surface of a PCM homogeneously and provide abundant active sites for photocatalytic reactions.
