Hydration of medium reactive industrial magnesium oxide with magnesium acetate Thermogravimetric study

Van Der Merwe E.M.; Strydom C.A.; Botha A. (2004)

Medium reactive magnesium oxide reacts incompletely with available water to form magnesium hydroxide. To enhance the hydration of medium reactive magnesium oxide, the effect of magnesium acetate as hydrating agent was ...
Hydration of medium reactive magnesium oxide using hydration agents

Van Der Merwe E.M.; Strydom C.A. (2006)

Water, magnesium acetate, magnesium chloride, acetic acid and hydrochloric acid were used as hydrating agents for an industrially obtained MgO sample. The influence of these different hydrating agents on the pH of the ...
The influence of hydrating agents on the hydration of industrial magnesium oxide

Matabola K.P.; Van Der Merwe E.M.; Strydom C.A.; Labuschagne F.J.W. (2010)

BACKGROUND: The influence of different hydrating agents on the pH of the hydrating solutions, rate of hydration of MgO to Mg(OH) 2 and product surface area was studied as a function of temperature ...
Influence of hydration time on the hydration of MgO in water and in a magnesium acetate solution

Aphane M.E.; Van Der Merwe E.M.; Strydom C.A. (2009)

The time required for maximum hydration of MgO obtained from the calcination of magnesite was determined. The MgO samples were hydrated for different time intervals in both water and magnesium acetate. A thermogravimetric ...
Purification of South African phosphogypsum for use as Portland cement retarder by a combined thermal and sulphuric acid treatment method

Van Der Merwe E.M.; Strydom C.A. (2004)

PHOSPHOGYPSUM IS A BY-PRODUCT OF THE manufacture of wet phosphoric acid, and most of it produced in the world goes to waste. The impurities in phosphogypsum greatly restrict its industrial use in Portland cement. We have ...
Quantitative thermogravimetric analysis of binary mixtures: Magnesium hydroxide and magnesium acetate

Van Der Merwe E.M.; Strydom C.A. (2004)

Thermogravimetric analysis is used to determine the amounts of Mg(OH) 2 and Mg(CH3COO)2 in a mixture thereof. The application and suitability of different analysis methods are discussed. In the first method the mass losses ...
