Soundless Cracking Agent
For demolishing concrete and rock
WITHOUT NOISE.VIBRATION FLY ROCK.GAS.
HSCA is a noncombustible and non-explosive material. It
is safe and convenient in transportation, storage and operation.
HSCA is a silent demolition agent which does not cause annul
Vibration, Noise, flyrock, ash and hazardous gas during
demolition.
Demolition.
Demolition and cutting are allowed to be used according
to working scheme.
HSCA can gain a high yield for mining of granite, marble
etc. It is very easy.
To crush & remain reinforced concrete structures on
demand during demolition. Easy to operate at job site.
HSCA is a kind of in organic material consisted of calcium,
silicon, iron and aluminum in the form of powder.
Expansive pressure (Map)
Expansive pressure of HSCA
The HSCA slurry should be poured into hole drilled into
rock or concrete. The expansive Pressure can be introduced
in the hoes in 2-3hours after filling, making Rocks, granite
and white marble crack.
The cracks further spread and become wider and wider with
time as to root out easy to rocks etc.
To keep dry in storage about a year of time of efficacy
can be reached.
APPLICATION OF HSCA
Mining and cutting of marble and granite. For mining of
marble and granite, the yield is 2-3 times higher with HSCA
than by current explosion method. Because of non-vibration
crush, the yield is also doubled.
Crushing and demolition of structures of concrete and reinforced
concrete HSCA can be applied in the field where cracking
by mean of explosive is not suitable. While crushing and
demolition is carrying. Workshop and traffic near operating
site is still.
CRACKING DESING OF HSCA
Hole diameter and hole space. Hole diameter 30-50mm.
Hole space in accordance with the following formula.
A=KD
Where, A-hole space (mm)
D-diameter (mm)
K-cracking coefficient

OPERATION OF HSCA AT JOB SITE
Drilling: drill hole with a air drill according to the requirements
of design. Stirring devices: 10-20 liter plastic or metal
barrel.
Mixer: allow small amount of HSCA to mix by hand, but need
using rubber glove. Measuring water devices: measuring glass
protector, rubber glove, protective glasses.
stirring: pour about 1.5litre clean water into a container
and add one bag of HSCA slowly (pour water 30% of HSCA by
weight) then mix well with a mixer until it becomes a slurry
of good fluidity . Filling: First of all, clean up the holes
before filling .
HSCA slurry should be poured into hole within 10 minutes
after mixing with water . For horizontal holes, a grouting
pump and a plug for stopping up are required, or fill the
holes with thick paste of HCSA.
Cracking and cutting time:
The cracks appear in 2-3 hours after filling, depending
on air temperature of rocks and concrete. The cracks further
spread and become wider and wider with time.
Points for attention.
For safety, protective glasses is needed when working. After
filling, do not look at any hole closely and directly. Keep
dry in storage. Make a choice among the types of HSCA products
and use one which is suitable to working temperature.
