• Usage Process

1. Drilling – initial step is to drill holes where you want use it.
   Distance between holes - 7-12inches(depend upon the type of stone and concrete)
   diameter of holes – 35-40mm
   hole depth - 95% of the length you want to break. (minimum 1.5ft)2. \

2. Mixing- proper mixing of powder into water in calculative way. (5kg in 1.6 ltr water)

3. Pouring- pouring the mixture into the hole 

• Safety Measures-

• safety googles must be worn during the whole operation

• wear gloves while filling the holes

• keep the material away from the water before use

HOLE DESIGNING FOR EXCELLENT RESULTS
MORTAR effectiveness depends on the placement, diameter and depth of the holes drilled in the material. The drilling must be done in relation to the job to be performed. The design OF HOLE should be done according to the AREA WHERE IT HAS TO APPLIED, secondary.
The hole design refers to the hole diameter and hole distance. For hole diameter between 30 to 50 mm, the hole spacing (distance between holes) should be in accordance with the following formula:
A = K x D
where, A - hole spacing (in mm), D - hole diameter (in mm) and K - cracking coefficient.

K value of rocks and concrete

Material to be cracked	K value	Steel contained (Kg/m3)
Soft virgin rocks	10 - 16	n/a
Medium hardness virgin rocks	8 - 12	n/a
Hard virgin rocks	5 - 10	n/a
Plain concrete	10 - 16	0 - 30
Reinforced concrete	8 - 10	30 - 60
	6 - 8	60 - 100

 K Value changes with the geometry and shape of rock or concrete

Lesser the free surface, smaller the K value	Greater the free surface, larger the K value

Hard STONE(GRANITE)	38 - 42	25 - 40	30 - 80	105%	18 - 25
Rock cutting	30 - 40	20 - 40	(0.6 - 0.9) A	75%	12 - 18
Plain concrete	38 - 42	20 - 30	(0.6 - 0.9) A	80% - 85%	12 - 18
Reinforced concrete	38 - 50	15 - 30	(0.6 - 0.9) A	90% - 95%	18 - 25

 

Note: Before PERFORMING with a test break, reference should be made to 'Hole Design for Rock' or 'Hole Design for Concrete' links (on the left) to assist in your special needs for successfully planning a CRACK design.

Estimating Quantity Required

Once the hole design is fixed, it is simple to figure out how much EXPANSIVE MORTAR you need. The formula is:

C = Kg/m3 x Number of Holes x Depth of Holes

General coverage: Normally one 44 lb (20 kilograms) box of SILENT CRACKING AGENT can fill up to 35 linear feet (about 10 meters) of 1½ inches
(3.8 centimeters) diameter holes. (Might not have to fill up every hole depending on application.) As a thumb rule: Each 5-kilo bag will fill 8 linear feet of 1½" hole, 10 linear feet of 13/8" hole, or 11 feet of 1¼" hole.
