Analysis of anhydrite gypsum effects on quality of cement

2016-10-25  As it is well known, the workability property of cement solutions depends on reaction rate of C3A with water and to justify this, retarder raw materials are used. In cement industry, natural gypsum (CaSO4·2H2O) is the most effective raw material for this purpose. In the natural gypsum sources, anhydrite gypsum can often be encountered, so its effect on cement’s quality parameters must be focused on [1-3]. Furthermore, in the many different literatures, the usage of industry wastes which contain CaSO4 on cement production is likely to be seen. Application of phosphogypsum can be given as an example for this case. Phosphogypsum is a raw material which is produced from orthophosphote as a byproduct and contains CaSO4 as a dust form. Remainder of phosphor and fluoride can be completely separated by washing and chemical ways. However, the gypsum in the phosphogypsum

Analysis of Phosphogypsum’s Physical and Chemical

The phosphogypsum (PG) sample produced as the waste of the phosphoric acid fertilizer plant from Guizhou, China was studied for its properties and as a material for anhydrite cement. The impurity content, type and distribution, as well as thermal behavior and solubility of the PG were carefully studied by XRD, DTA techniques and gravimetric determination.

Project Report on CEMENT PLANT USING CLINKER

2020-12-4  Clinker, when added with gypsum (to control the setting properties of cement and ensure compressive strength) and ground finely, produces cement. Clinker can be stored for long periods of time in a dry condition without degradation of quality, hence it is traded internationally and used by cement manufacturers when raw materials are found to be scarce or unavailable.

Synthetic Gypsum an overview ScienceDirect Topics

Gypsum board manufacturers are increasingly relying on “synthetic” gypsum as an effective alternative to natural gypsum. It is estimated that roughly 45% of the gypsum used by U.S. manufacturers in 2010 was of the synthetic variety. Synthetic gypsum and natural gypsum have similar general chemical compositions (CaSO 4 ·2H 2 0). The vast majority of the synthetic gypsum used by the industry is a
