SINO CRACK expansive powder for quarry stone block - I,II,III,IV

SINO-CRACK is a soundless and safe demolition agent which is quite different from ordinary demolition agents such as explosives and dangerous materials. It does not cause any fly rock, noise, ground vibration, gas, dust or any other environmental pollution when used properly. As requirements for demolishing rock and reinforced concrete in construction increase in tight quarters, the use of explosives and explosive agents is becoming more restricted as far as safety and environmental pollution problems are concerned.

SINO-CRACK can be used in an almost unlimited range of applications. It’s particularly used for breaking, cutting or demolishing stones, concrete and reinforced concrete. It is ideal for use in situations where surrounding buildings or other structures would be damaged by flying debris or vibration. It maximizes production circle, product output, the rate of finished products and therefore profits, in quarrying and mining as it avoids waste of valuable stone.

Generally, the compressive fracture stress of rocks is 1000 to 2000 kg/cm2 and that of concrete 150 to 500 kg/cm2. However, the tensile fracture stress is very small, i.e., it ranges from30 to 60 kg/cm2 in normal rock, 40 to 70 kg/cm2 in concrete,100 to 120 kg/cm2 in reinforce concrete(steel bar inside),, respectively. SINO-CRACK? can provide a tensile stress almost 500 to 600kgs tensile stress in based on a fracture, all kinds of rocks and concrete can be cracked and broken by using SINO-CRACK? when appropriate boreholes are properly drilled.
