ABSTRACT Calcined titanium gypsum was investigated by the ways of XRD (powder X-ray diffraction), XRF (X-ray fluorescence) and TG-DTA (thermogravimetric–differential thermal analyses). It was employed as raw material for making lightweight materials. The influence of cement, amount of water/solid (W/S) ratio, water-reducing agent, citric acid content and the hydration age on the gypsum blocks was investigated. The results showed that the optimum W/S ratio, cement content and water-reducing… 

Preparation and Characterization of Lightweight Wall Materials Based on a Binder Mainly Including Phosphor-gypsum

In this paper, the specimens of phosphor-gypsum (PG) based binder and the specimens of its lightweight mortar (LM), further the specimens of its lightweight wall materials (LWM) were prepared using

The study on the effect of flotation purification on the performance of α-hemihydrate gypsum prepared from phosphogypsum

The mechanical strength of high strength gypsum prepared from PG concentrate was significantly better than that of raw PG, indicating that flotation purification can effectively improve the performance of PG.

Laboratory Evaluation for Utilization of Phosphogypsum through Carbide Slag Highly-Effective Activating Anhydrous Phosphogypsum

Carbide slag was used as an activator to improve the activity of anhydrous phosphogypsum. Carbide slag could greatly improve the mechanical strength of anhydrous phosphogypsum than K 2 SO 4 . The



Utilization of phosphogypsum as raw and calcined material in manufacturing of building products

Use of industrial byproducts as alumina sources for the synthesis of calcium sulfoaluminate cements.

When examined through differential thermogravimetric and XRD analyses, a synthetic CSA clinker showed a hydration behavior almost similar to that of an industrial CSA cement containing the same amount of gypsum.
