Concrete Admixture – Alkali-Free Accelerator for Shotcrete (MNC-Q2)

 

Alkali-Free Accelerator for Shotcrete

(MNC-Q2)

Description

MNC-Q2 is a high-performance alkali-free concrete accelerator for sprayed concrete. It is a liquid form which dosage can be varied as according to the designed setting and hardening times.

Application

MNC-Q2 is suitable for all applications, where high and early strength, good final strength and extremely thick layers are required.

• Temporary and permanent rock support in tunnels.
• Rock support in mining.
• Poor ground conditions.
• Tunnel linings, cement ground injection and foam concrete which need acceleration of cementitious grouts.

Features

• Quick setting property allowed with rapid work progress and construct thick sprayed concrete linings via layered application during one construction sequence. Initial setting time is 2 min to 5 min, final setting time is 3min to 10min.
• Good adhesiveness, one spray layer can be 8 mm to 150mm.
• High strength and concrete performance durability.
• Easy handling as well as facilitating accurate addition to concrete.
• Very low dust production with good working environment.
• Lower handling cost.
