Low Heat Cement | Cement Australia

Low Heat Cement is designed to provide a lower 'heat of hydration' in concrete. This attribute makes it ideal for mass concrete pours where the rate of temperature rise and the maximum temperature achieved must be controlled in order to reduce the risk of thermal cracking. This technology delivers improved later-age concrete strength.

Waste Heat Recovery in the Cement Process

Typically, cement plants do not have significant low ­ temperature heating requirements, so most waste heat recovery projects have been for power generation. The amount of waste heat available for recovery depends on kiln system design and production, the moisture content of the raw materials, and the amount of heat required for drying in the raw mill.
