GK-10A Anchoring Capsule

Cement based materials

未标题-1.jpg

DESCRIPTION	GK-10A anchoring capsule is made from high strength materials as aggregate, cementitious materials as binder, supplemented by inorganic of high flow micro-expansion anti-segregation and organic other substances. It has no corrosion effect on steel structure and has excellent features of advanced technical formulation, stable performance, easy application, large anchoring force and stable development of later strength, etc.
USES	GK-10A is widely used in rock bolt support in mines, hydraulic tunnels, underground workshops, highway traffic, etc; as well for special construction needs, such as leakage stoppage in emergency.
CHARACTERISTICS	GK-10A has advantages of following: * High reactivity: setting faster, strength develop faster and anchoring force reliable; * No shrinkage: limits expansion offset contraction, ensure effective contact with the rock; * Chlorine-free: develops early strength without chlorine; * Encapsulation: limits the loss of grouting holes or flowing water conditions.

APPLICATION
RECOMMEND DOSAGE	/
USING METHOD	1. Select suitable diameter of cementitious anchoring capsule based on the requirements of design, and check whether it is spoiled by moisture. 2. Immersion: The single-hole design should be carried out in the use quantity of one-time immersion, while water depth ≥30cm, and general immersion time of 30—90s, which should be determined by testing. 3. Put the soaked anchoring capsule into the bolt hole one by one, and ensure fulfill.
NOTES ON APPLICATION	1. Once unpacked to use, the inner packing bags of the remaining products should be tied tightly to prevent moisture. Pay special attention to moisture-proof storage of batch products. In case of dampness, the anchoring capsule drum will become hard, which will affect the anchoring force and even fail. Therefore, the moisture-affected anchoring capsule should be used after testing, otherwise it will affect the spraying quality and construction safety.
	2. There should be no water and residue in the anchoring hole, otherwise it will affect the anchoring force and the anchoring quality.
