Vulcan Aids Quarry Optimisation

Maptek Vulcan helped Titan Roanoke reduce waste and produce low alkali cement, while complying with stringent new emissions regulations.

The Titan America Roanoke Cement Company in Troutville, Virginia operates an open pit quarry specialising in limestone and shale production. Cement products are distributed to regional construction industries.

Since 2011, Titan Roanoke has focused on reducing waste from stripping, and at the same time producing low alkali cement for customers.

Low alkali cements are Portland cements with a total content of alkalis not above 0.6%. This is particularly beneficial where concrete is at risk of deterioration, for example when in contact with soil, groundwater or seawater.

Low alkali cement is also recommended when reactive aggregates are used to reduce the effect of alkali-silica reaction which can result in expansion leading to cracking.

Challenge

Recently proposed EPA regulations in the USA will require cement companies to drastically reduce sulphur emissions.
