We are offering silent demolishers-novablast.
thank you very much for your enquiry for rock blasting.
we can take up complete contract or supply of rock cracking
chemicals which comes in 5 kgs packets with one box of 20 kgs
the usage instruction is as follows.
drilling
1. Drill holes using an air hammer drill and appropriate drill bit
specific to the rock type.
2. Holes should be drilled no further than 30-60cm (1 ft-2ft) apart.
Note. In reinforced concrete recommended no more than 20cm (8") apart.
3. Recommended hole diameter 38mm-50mm (1 1/2" - 2.0") . Depth would
be 70-90% of the way depending on the type of rock/material to
be removed.
mixing
1. For regular safety reasons and mixing small amounts by hand, it
is recommendable to use rubber gloves.
2. In a bucket, combine 1.5 liters of water to one 5kgs bag of
cracking material .or pour water and cracking material as a rate of 1.3
units by weight.
3. Mix well, using a drill and paddle is recommended . If mixing
with a stick or other method, make sure powder is completely dissolved into
the water.
mix to the slurry.
filling
1. Clean holes before filling using air hose remove excess dust from
drilling.
2. Cracking slurry should be poured into holes within 10-15 min, after
mixing. Do not fill to the top , only fill the holes about 15mm (1/2" to 1 )
from the top.
3. Mix well and pour into holes while agitating the hole to make sure
no air gaps are in the hole. Example; using a piece of rod or stick to poke
holes.
4. For horizontal holes, a grouting pump would be most reliable to
poor.
cracking or cutting time
the cracks appear in 40-60 min after filling , depending
on the weather, rocks, and concrete type. The cracks become wider within
time
(maximum 48 hours expanding time). no licence required
to use it
