Effect of Admixing Fly Ash on Cementing Characteristics of Magnesium Oxychloride Cement
Investigations pertaining to the effect of admixing
different amounts of fly ash on setting characteristics and
compressive strength of magnesium oxychloride cement has been
carried out in this paper. For this purpose, two different dry mix
compositions (1:0 and 1:1) of magnesia and dolomite were
prepared and 5 %, 10 %, 15 % and 20 % fly ash were added in
dry mixes. The dry mixes were then gauged with 24 °Be
concentration of magnesium chloride gauging solution. It was
observed that initial and final setting times of cement blocks tend
to increase with increasing amount of fly ash in dry mix. MOC
cement blocks of 1:1 composition admixed with fly ash displayed
good cementing characteristics.
