Tunneling - Shotcrete Additives

Apral

Apral is an accelerating admixture for shotcreting works without affecting the final mechanical strength. It is an alkali-free product based upon an aluminium oxide-in-water solution.
It is suitable for use in both wet and dry mix shotcrete and provides faster setting times to shotcrete for use in tunnelling, mining, dams, shaft sinking, slope protection and in general construction applications when there is a need to accelerate the set times of sprayed concrete. It is also suitable for cold weather conditions.

Important note: The Bekaert-Maccaferri joint venture: In October 2014, we entered into a global sales and distribution JV with Bekaert. The resulting joint venture, BekaertMaccaferri Underground Solutions will serve underground construction markets on a worldwide basis, except in mainland China and Hong Kong, Argentina, Brazil, Paraguay, Peru, and Uruguay, where Bekaert and Maccaferri will continue to operate independently.
