Study of Concrete Destruction Techniques Using TNT and C_4 to Optimize the Power of Explosives

摘要

Explosive technology is the fracturing of materials by using a number of calculations from the explosion so that the volume of breakable material can be determined. This study is to find out how the 30 cm diameter bone bridge concrete technique and how the explosive strength difference of explosive TNI and C4 at the same weight to the concrete of the bridge. The method used is literature study and field experiments. The results of this study were obtained for effective and efficient blasting of concrete and resulted in an optimum explosion with several steps: calculating concrete strength by Core Drill test, calculating the amount of current required, calculating the amount of C4 and TNT explosives required. The explosive strength difference of explosive TNI and C4 at the same weight to the concrete with the value of fc = 229.31 kg/cm~2 Core Drill test. C4 explosives have more complete destructive power compared to TNT and the number of effective explosives required to destroy the concrete with the strength of fc = 229.31 kg/cm~2 is 122 g.
