1.For mining, rock or concrete cutting and demolition; 2. High yield, Low cost; High efficiency. 3. Easy and sate to use.

BREAK-AG ( Expansive Mortar/ Soundless Cracking Agent) is a kind of grey powder. It consists of calcium oxides, silicon dioxide, ferric oxide and little other ingredients. In order to meet different worksite temperature, there are three main types of BREAK-AG, they are HSCA-I(25°C~40°C), HSCA-II(10°C~25°C), HSCA-III(-5°C~10°C). When the BREAK-AG mixed with appropriate water and poured into the pre-drilled holes, it will start to expand after half an hour, the expanisve power is increasing as time goes on. It can get 100-123 Mpa expansive power after some hours. Generally, the rock or concrete belongs brittle material, their tensile strength are far less than the compressive strength (for the tensile strength, rock is 1.96-30Mpa while concrete is 1.5-4.0 Mpa, they are equal to 1/10-1/20 of their compressive strength). Therefore, reasonable hole design can easily crack the rock and concrete or reinfored concrete by our BREAK-AG. As usal, it can crack the materials in around 2-24 hours. It is soundless, non-explosive, no noise, no vibration, no flying rock during the process of demolition. 

Comparing with explosive or other demolition tools, the BREAK-AG is much safer, lower cost, higher efficiency,etc. Nowadays, it is widely used for quarrying, rock excavating and removing, concrete & reinforced concrete demolition, such as road/tunnel/ trench/boulder/ bridges/building demolition and construction, concrete foundation removal , underground demolition and other civil engineering demolition.
