ATEK-QL(A)
Alkaline liquid set accelerator for sprayed concrete

Description
ATEK-QL(A) is a liquid accelerator for wet shotcreting.
For NATM shotcrete system and used generally for subway construction or most kinds of tunnel constructions.

Use

• Most of all sprayable concrete constructios.
• Rock wall, slope protection.
• Mine system.
• Other sprayable concrete

Features

• Makes prompt congelation, solidification.
• Raises the compressive strength by use of refined raw materials.
• Low rate of rebound loss.
• Non chloride, no corrosion on reforced rods.
• Initial Setting time is quick more than the other accelerators.
  
  

Technical data

Application

• ATEK-QL(A) should be injected by compressed air.
• Injections are to be made by hose and air pressure adjusting pressure controller for continuous mixture.
• It is advisable that utilizing our superplasticizer ATEK-PC will efficiently help lowering W/C and smooth pumping.
• Ideal concrete temperature prior to application is 15°C

Caution

• It is a high alkaline material.
• Be cautious not to contact with skin
• Prepare pure water near the job site
• Keep storing tank warm as viscosity gets higher when temperature is low
• Do not mix with other accelerators. Mixing aluminate system with silicate system will harden

Storage

• If stored in tightly closed original containers under the given conditions, ATEK-QL(A) has a shelf life of 1 YEAR
• Store the product in closed container at a temperature between-20°C and +50°C. (But setting time is poor, If you do not heating).

Packing

• ATEK-QL(A) is availabe in 200 LSTEEL or PE drums and 1000L PE tanks.
