BETONAMIT® was developed during the 70s by KUBATEC in Liechtenstein and was the first such product to enter the European market. The swelling effect of quick lime was already partly used by the ancient Egyptians thousands of years ago to split rocks and for targeted demolition. In recent decades we have built up an enormous know-how to optimise and control this chemical process and deploy it for safe demolition. Very simply explained, the calcium oxide (quicklime) reacts to the addition of water to become calcium hydroxide, causing a multiplication of its volume. This almost unstoppable volumetric transformation is used for safe concrete demolition and breaking rock. The following further designations are often applied to BETONAMIT®: swelling pressure agent, swelling demolition agent, swelling agent, swelling explosive, expanding cement, expansion cement, expansion agent, cold explosive, cold blasting agent.
