FRACT.AG ® is a highly expansive mortar to demolish and cut rocks and concretes. FRACT.AG ® swells when poured into a hole and develops a pressure higher than 8000 t/m2 on the hole walls. Thereby breaking them open. FRACT.AG ® is environmentally friendly because it releases no toxic fumes or harmful substances of any kind.
FRACT AG ® can be used in an almost unlimited range of applications and particularly to break, cut, or demolish rocks, concrete and reinforded concrete when explosives cannot be used for safety reasons. It is ideal for use in situations where surrounding buildings or other structures would be damaged by flying debris or shock waves. It maximises production time, product output and therefore prorofits, in quarrying and mining as it avoids are loss or dispertion. There is no need for shaft or pit evacuation during blasting.
FRACT.AG ® can be used on any type of rock formation,
concrete, reinforced concrete or tiled structure in:
‘excavating foundations;
levelling rocks for road works;
excavating trenches for pipe laying;
underground excavations;
marine and submarine excavations;
removing boulders;
demolition of concrete or reinforced concrete ploes,
towers, walls, wharves, etc.;
* demolition of foundations;
‘© demolition of breakwaters/jetties;
‘* demolition of tiled and refractory structures;
FRACT.AG @ provides the most technically suitable and
cost-effective solution in:
* restricted demolition of rock and concrete structures
where nearby structures must be protected from.
shock waves generated by explosions;
* pre-splitting of rock formations, to create isolated
blocks that can then be more easily demolished;
* cutting blocks of marble and granite more economically than with the traditional helicoidal wire-cutting method;
* ecxavations and demolition of rock formations or
cement/concrete structures where the use of
explosives would be expensive due to long
operating times, special transport, storage and
handling precaustions and the need to comply with
public safety regulations.
FRACT.AG @ is a powder that must be thoroughly
mixed with clean water before use, in a ratio of 30%
the overall weight. Put the required amount of water
into a large container (1.5 liters for each 5 kg
package)., gradually add the powder to water stirring
all the time to abtain a smooth, lumpfree mortar. Tou
the mortar into the prepared holes within 5 to 10
minutes.
‘Slope horizontal holes to allow an easy pouring of
FRACT.AG ® (should some of the mortar leak out of : hole, stop it with a piece of spft sponge).do not plug the holes, Cover them only in a event of rain using a waterproo sheet. The holes must be perfectly dry before pourin in the mortar. If there is heavy leaking, slits or crack: it is advisable to place a polyethylene sheath into the hole and before filling it with the mortar. The distance between the holes varies depending on the size of hte hole (from 32 mm diam. to 50 mm diam.) and the pype of material to be demolished or cut.
‘Anyone can use it, in any situations, becuase FRACT.AG @ is perfectly safe, soundless and nonhazardous. It does not leave debris or dust, nor does it form gas or cause any shack waves. Unlike explosives, no permit is repuired to use FRACT.AG ® . Unskilled labour can be very easily trained to use FRACT.AG ® in a short time. Demolition or cutting operations using FRACT.AG © can be interrupted at any time; simply remove the product from the hole by boring another hole into the existing one.
* Production can be significantly increased as it
can be continuously conducted safely.
* Stopping width can be easily
controlled as there is no nal ieee
waste to deal with. Mining -
operations can be conducted
in working environment
unhampered by flying debris
making cleaning-up
unnecessary. 3
* Efforts are concentrated on ¥
exploiting the oreor precious
stone-bearing reef - a factor
which is most important in B
marginal situations.
* The product is ideal for the —_
mining of emeralds and other precious stones,
as brittle material is not destroued or broken up.
* FRACT.AG @ has a shelf-life of 2 years, thus
obviating problems associated with out-of-date
material as may be the case with explosives and
detonator fuses.
* We believe hoisting operations can be
minimised, significantly reducing electricity and
maintennance costs.
* Mines employing only FRACT.AG ® would not
need to evacute personnel from the shaft before
blasting. Labour can therefore be more
productively and cost-effectively employed, ths
safeguarding jobs.
* Because of the all-round saving particularly in
the areas of labour, winching, electricity
maintenance and cleaning, many marginal mines
could avoid closure via the use Of FRACT.AG ®.
* Mine safety is promoted becuse there is no
danger of underground fire caused by explosives
or igniter cord - There is no post-blast caused by
misfires - Mine safety is further enhanced since
the disturbance of the surrounding rock is
minimal as there is no concussion or vibration
and there are no blasting accidents.
* Heavily faulted areas are mineable.
Six types of FRACT.AG ® are available on the market:
‘* RED - For temperatures near 5° C (ab.41° F)
* GREEN - For temperatures from 5° to 20° C
(41° to 68°F)
* YELLOW - For temperatures from 20° to 35° C
(68° to 95°F)
'* GOLD - For temperatures from 35° to 50° C
(95° to 122°F)
* BLUE - For temperatures from 50° to 60° C
(122° to 140°F)
‘SILVER - For temperatures from 60° to 70° C
(140° to 158°F)
FRACT.AG ® C was designed to solve some of the minor snags encountered when using expansive mortar FRACT.AG ® in powder form. The product is conveniently supplied ready-mixed in plastic-wrapped cartridges and as such there are no limitations to its use in any working environment. Currently 6 types of FRACT.AG @ C are available: ‘* RED - For temperatures near 5° C (ab.41° F) ‘* GREEN - For temperatures from 5° to 20° C (41° to 68°F) ‘* YELLOW - For temperatures from 20° to 35° C (68° to 95°F) '* GOLD - For temperatures from 35° to 50° C (95° to 122°F) * BLUE - For temperatures from 50° to 60° C (122° to 140°F) ‘* SILVER - For temperatures from 60° to 70° C (140° to 158°F)
Mixing is not necessary thereby eliminating the Possibility of using the wrong amount of water, since it will only absorb the required amount. It can be used anywhere without taking special measures )i.e. roofs or walls holes). Reaction time is quicker therefore it demolishes or cuts faster.
Cartridges are available in 100 cartridge - boxes. Each cartridge is 28 mm in diameter, 22 cm long and contains 200 gr of FRACT.AG @. they must be used in 32034 mm diameter holes. 100 cartridges are enough for a length of 14 to 16 meters of holes.
The distance between the centres of the holes in rock or non-reinforced concrete should be 30 to 60 cm, depending on the diameter of the hole. With reinforced concrete, the distance should be 20 to 30 cm. The smaller the diameter of the hole, the closer the one hole can be to another (eg: diam. 32 = 30 cm; diam. 35 = 40 cm; diam 40 = 45 cm.). For the best possible use and to obtain best results, it is advisable to carry out preliminary tests with FRACT.AG @ before starting work. Large diameter holes positioned closer together accelerate breaking times. When using FRACT.AG ® with highly absorbent materials like concrete, the holes should be dampened before the mortar is poured, making sure howevber, that there is no presence of water.
