KEM CRETESET 100 AF
Alkali Free, Liquid High Performance Set Accelerator for Wet-mix Sprayed Concrete
Ref : CA/SA-V2-1215
Description
KEM CRETESET 100 AF is a high performance alkalifree set accelerator for sprayed concrete. It is a liquid admixture whose dosage can be varied to the desired setting and hardening times.
Uses
KEM CRETESET 100 AF is suitable for all applications where high early strength, good final strength and thick layers are required:
Temporary and permanent rock support in tunnels
Rock support in mining In poor ground conditions
Slope stabilization
Also suitable for acceleration of cementitious grouts, such as used in TBM tunnel linings, cement ground injection and foam concrete backfill operations
Advantages
KEM CRETESET 100 AF is the ideally suited accelerator for wet mix sprayed concrete for rock support because:
The quick setting property allows rapid work progress and the ability to construct thick sprayed concrete linings via layered application during one construction sequence.
The unique product formulation provides continual early-age strength development whilst also achieving excellent long-term strength and durability.
KEM CRETESET 100 AF is a liquid product and thus provides easy handling, as well as facilitating accurate addition to the concrete.
Very low dust production and therefore a good working environment.
KEM CRETESET 300 P
Alkali- free non caustic & non toxic high performance powder accelerator for drymix shotcrete
Ref: CA/SA-V1- 0713
Description
KEM Creteset 300 P is a high performance alkalifree, non caustic and non toxic accelerator for the use in drymix shotcrete processes. It is a powder additive whose dosage can be varied to the desired setting and hardening times.
Uses
KEM Creteset 300 P is suitable for all applications where high early strength, high final strength and large thickness are required:
For temporary and permanent rock support.
For final lining (one pass lining).
For repair works.
In tunnels.
In mining.
Advantages
The quick setting properties allow:
Overhead layer thicknesses of 100 -150 mm in a single application.
Rapid work progress.
The unique formula:
Provides good early strength development
Limits the decrease of final strength
Improves durability as compared to mixes with traditional accelerators
