Abstract
Phosphogypsum (PG) is a naturally occurring part of the process of creating phosphoric acid. The raw phosphate is treated by sulphuric acid, deside the main product phosphoric acid, phoso-gypsum and small quantity of hydrofluoric acid are obtained. The aim of this work is to study the possibility of using granulated blast furnace slag (GBFS), PG and (OPC) for preparation of supersulphated cement (SSC). The hydration, strength development of the hydration products of SSC are characterized in hydrated pastes cured in tap water up to 90 days. Some selected samples are examined by XRD and DTA techniques to show the main hydration product.
