ANHYDRITE BINDER CALCINED FROM PHOSPHOGYPSUM
The anhydrite binder calcined with the addition of 5% ground glass exposes the best physical and mechanical properties: the setting duration up to 13-38 min, the compressive strength of the dry samples is 30.74 MPa. INTRODUCTION Anhydrite cement is largely applied in the construc- tion industry in many countries.(PDF) Anhydrite binder calcined from phosphogypsum,The anhydrite binder calcined with the addition of 5% ground glass exposes the best physical and mechanical properties: the setting duration up toanhydrite binder calcined_Small Mobile Crushing Machine In,,ANHYDRITE BINDER CALCINED FROM PHOSPHOGYPSUM Anhydrite binder calcined from phosphogypsum Ceramics – Silikáty 54 (2) 152-159 (2010) 155 was 9.1-9.2. The specific surface area was 1900 m2/kg. The cristabolite, the lisetite, the vaterite,Characteristic properties of the anhydrite binder produced,,The formed specimens from this composition of the anhydrite binder calcined at the temperature 900°C reach the early compressive strength -13.14 MPa after 3 days.,Optimization of the activation process for natural anhydrite,Because the author found that PG calcined at 800 °C showed a good performance , , all the samples were calcined at 800 °C for three hours in a muffle furnace. Then, the A1P and A1F series were aged for one day at room temperature, milled for 15 min, and sealed in the bag. Finally, the anhydrite prepared from PG contains different content of converted phosphorusCalcined Gypsum Case,ANHYDRITE BINDER CALCINED FROM PHOSPHOGYPSUM. case 500-1200 C, the compounds C3S, C3A a.o. can be formed, which are in the composition of Portland cement. The calcium silicates, aluminates and aluminosilicates for example C2S, C3S, C3A, AS2 a.o. can be formed between gypsum or phosphogypsum and kaolin at high temperature. The X-ray
