Mining is a very demanding sector: the imperatives of productivity and profitability are constantly challenged by the nature of the rock structure. More than in any other sector, the rapidity with which concrete can be placed and its durability in an extreme environment are determining factors. With their specific properties, Imerys Aluminates cements and derived products achieve exceptional levels of performance, often indispensable to mining operations.
There are three forms of Kerneos products used in the mining industry:
1. Binders, used to manufacture fast-setting mortar and concrete with exceptional durability in an aggressive environment.
2. Pre-formulated mortar and concrete, used to obtain specific properties.
3. Reagents in a very wide range of products formulated by chemists specialising in mining applications to meet a whole range of diverse needs.
Aluminous cements are used in a wide range of applications where their specific properties can be particularly beneficial:
The aluminous cement based-products manufactured by Kerneos may be applied by various techniques, according to needs and the applications concerned: onsite pouring, dry or wet spraying, long-distance pumping, injection into solid rock, etc.
Similarly, the kinetics of setting and hardening may vary over a wide range of time as required, from near instant setting to setting over more than 24 hours.
Calcium aluminate concrete minimizes maintenance and operating interruptions, improving the cost efficiency ratio.
Thanks to calcium aluminate cement and concrete, and especially Ciment Fondu®, mining engineers throughout the world have been able to find cost-effective solutions to a wide array of complicated situations where the performance offered by standard Portland cements is insufficient:
Kerneos offers a range of products tailored to the specific needs of the mining industry. These products vary from country to country and according to the application.
Among the most common:
