Procedure with BETONAMIT®

BETONAMIT® | for vertical and downward drilled boreholes

Betonamit Gebrauchsanweisung rotFirst step is to drill boreholes with a diameter of 1Ľ”-1˝”. The optimal distance between each borehole is around 10 times its diameter, thus around 30-40 cm. The boreholes must be clean and dry. Now put the BETONAMIT® powder into the mixing countainer. Add 1.0 until max. 1.2 litres (per 5 kilogram) cold and clean water. Mix it with an agitator until it turns into a flowable, homogenic mixture. Fill the borehole directly with the mixture. The processing time should not exceed 5 minutes. No additional mechanical closure required. For special applications of over 40 mm it’s mandatory to consult the manufacturer.

Procedure with BETONAMIT® Special (malleable)

BETONAMIT® Special | For horizontal and upward drilled boreholes

Betonamit Spezial GebrauchsanweisungFor overhead works and horizontal boreholes, BETONAMIT® Special (malleable) comes to use. The only and major difference is that BETONAMIT® Special will not be fluid after mixing. It will present a malleable mixture so that you can fill horizontal and upward drilled boreholes without it running out.

Procedure with BETONAMIT® Special

  • Drill holes
  • Put the powder into a mixing cointainer
  • Add water (0.5 litres/2.5 kg)
  • Mix it well with the agitator until it turns into a homogenic, malleable mixture
  • Roll in into shape and fill the holes
  • Compress the mixture in the borehole with a stick
  • Repeat the procedure until the borehole is completely full

Due to the laborious processing, we recommend, when possible, to drill downwards and primarily use BETONAMIT® liquid.

Positioning the boreholes

Principle: The cracking always occurs in the direction of the lowest resistance. A larger borehole diameter means more force, shorter reaction time and wider cracking. A lesser spacing of the boreholes means smaller fragments and a shorter reaction time.

SEPARATING / SPLITTING

The holes are drilled in a line with a short spacing between them. Cracking occurs from hole to hole. In this way, objects can be relatively precisely separated resp. split.

SEPARATING / SPLITTING

BREAKING UP

The boreholes are drilled offset in several rows to obtain the smallest possible fragments. The more boreholes, the smaller the fragments. Cracking occurs criss-cross.

BREAKING UP

DIGGING / REMOVAL

If there is no free side available for displacing the material, space must first be created. This is possible either by opposing boreholes at an angle of 35-60° or even on one side at an angle of 45-60°. Angled boreholes are also suitable for achieving a large-scale lowering of the ground level. (Cellar etc.)

DIGGING / REMOVAL

ROCK EXTRACTION / ROCK DEMOLITION

There are various techniques for rock extraction or rock demolition. The drilling schedule is selected according to the shape and constitution of the rock or adapted to local regulations. The principle always remains the same. First, try to create a free side, that is, a straight edge. From this edge the extraction can then be continued for as far as is required.

ROCK EXTRACTION / ROCK DEMOLITION

EXCAVATION

With rock excavation, the boreholes are drilled and filled in several rows 5-10 inches (10-15 cm) below the required ground level. The substrate is thereby broken and loosened such that it can then be removed by excavator or, in part, also by hand. Again, the non-explosive cracking agent is most effective when the boreholes are drilled somewhat obliquely, so that a part of the force is exerted upwards.

EXCAVATION

QUARRIES

The employment of BETONAMIT® in quarries etc. is becoming ever more important. The constraints on the use of explosive blasting agents and their storage are becoming ever more onerous in many countries, hence alternatives are increasingly sought after. The optimal application in these areas is very much dependant on the given local situation as well as on the material to be extracted. We would be pleased to work with you to develop a concept customised to your needs. (e.g., marble quarrying, granite quarrying, etc.)

Material consumption

Material consumption is calculated as the sum of the depths of all boreholes times the corresponding factor (table) of the used borehole diameter. In the table you will find the factors in the most common weight and length units of the construction industry as well as in combination.

Materialverbrauch

Examples:

You have 15 boreholes (ř 35mm) with a depth of 0.6 metres
Factor at ř 35 mm: 1.6 (table)
15 boreholes x 0.6 m x 1.6 kg = 14.4 kg BETONAMIT®

 
Technical specifications

The following table shows the anticipated reaction time as a function of the temperature. In addition, here you will find further helpful information about the application. Since the borehole diameter has a huge impact on the expansion force and reaction time, we recommend, insofar as possible, selecting the largest possible drill size.

TIP:

BETONAMIT® continues to expand over a period of several days. This means that the more time you give BETONAMIT® to work, the easier the subsequent removal of the fragments will be. Ergo, be patient and let BETONAMIT® do the tedious work for you.
