| BREAK-AG ( Expansive Mortar/ Soundless Cracking Agent) is a kind of grey powder. |
|
|
|
| In order to meet different worksite temperature, there are three main types of |
|
| BREAK-AG, they are HSCA-I(25℃~40℃), HSCA-II(10℃~25℃), HSCA-III(-5℃~10℃). |

|
| 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. |
