Expansion mortar is also called Soundless Cracking Agent  or Non-explosive demolition agent. It consists of calcined oxides of calcium, silicon and aluminum etc. It can get more than 50 Mpa  expansive capability after mixed with water. It is widely used in mining, rock cutting, concrete & reinforced concrete fracturing,building & road & tunnel construction, underwater demolition and other civil engineering demolition in India, Saudi Arabia , Egypt, South Africa, USA, Canada, Brazil, Argentina, Ireland, Finland etc.

Type and Temperature scope:
Since the temperature is an important element that influences the reaction time of the HSCA, Prodemo
decided to be specialized in the production of 4 types of HSCA which are adapted to different temperature
levels as you can see in the following table:

HSCA Type Temperature level
C1 25ºC-40ºC
C2 10ºC-25ºC
C3 5ºC-10ºC
C4 40ºC-55ºC

Note: The HSCA C4 Type is specially designed for the Saudi Arabia extremely high temperature .


Product features:
Within 3-6 hours safely demolish rocks with free surface or concrete,Higher expansive pressure 1.5-2 times than normal stone cracking powder,Without blown-out shot during appplication.

Soundless Cracking Agent is a non-explosive demolition agent that has the ability to safely demolish rocks and reinforced concrete, cement without producing noise, vibrations, debris launches or environmental
pollution, To carry out the demolition CRACKMAX requires only the drilling of the rock or cement to be able to drain the CRACKMAX and water mixture into the holes. The demolition is completed with utmost safety without the use of protection as in the case of explosives.
CrackMax Expansive Mortar can be used safely, while providing controlled expansive cracking. It can also be used to achieve the perfect slabs and blocks from onyx, marble, granite, or any other type of stone. as non-explosive, soundless and safe demolition agent provides the most technically suitable, environmental friendly and cost-effective alternative solution in dimensional stone application.
 
Working conditions:
1. Before the blasting, the structure, nature, working environment, engineering quantity, required degree of fracture, and construction period requirements of the building (structure) shall be met. Detailed investigations were carried out on temperature conditions, steel bar specifications and reinforcement conditions. Design the blasting operation, select the crushing agent according to the actual situation, determine the required drilling parameters, drilling distribution and blasting procedures.
2. The blasting of foundations, pile heads, underground facilities or rocks shall be excavated from the surrounding soil layer until the bottom of the blasting is 100 to 200 mm.
3. When dismantling the reinforced concrete, the distribution of the steel bars should be first identified, and then drilled, and the stirrups and part of the vertical bars of the blasting body should be cut with an oxyacetylene flame.

Operating process:
1. The construction procedure of static blasting is: blasting structure (body) investigation → blasting design → selecting crushing agent and drilling parameters → drilling → cutting part of steel bar → filling and pouring → health → secondary crushing → cleaning.
 
2. The blasthole arrangement depends on the degree of freedom of the structure, or creates as many free surfaces as possible, and adopts different hole-to-hole methods for different free faces. Vertical, horizontal, oblique, etc. can be adopted.
