Dear All,

Compliments of the season to you all.

Please we changed our cement additive limestone source, the new limestone contains higher level of SO3, and due to this, our cement SO3 is going higher (SO3 analysis using XRF). 

Please do I need to change my Gypsum consumption to cater for this or the limestone SO3 does not take part in ettringite formation.

Please I do not have the setting time results yet (and i need to take a decision to prevent customer complaint).

Please kindly give your expert opinion with reasons.

 

Thanks
