Useful explosives in construction
Posted on | May 13, 2010 | No Comments
The most useful types of explosives are safe to handle as long as they are handled properly. For instance, Nitroglycerin was the first type of dynamite and it was very unstable. This made it hard to be safely used, miners would have to carry this stuff over rough roads with no type of cushion or shocks on the wheels. Steel banded wooden wheels were used on wagons to pull nitroglycerin which was very dangerous work. So, Alfred Nobel figured out how to make solid nitroglycerin which is less sensitive to shock as liquid nitroglycerin. This new solid nitroglycerin could now be taken almost anywhere safely. Mt. Rushmore had almost 40% of the stone removed with solid nitroglycerin “Dynamite”. Dynamite helped build America from mine shafts to making Niagra Falls water fall in a more even way. Now another usful item is called a hilti gun, The Hilti Gun uses gun powder to accelerate nails to such a high velocity that the nail punches through concrete and steel and remains lodged in place now able to hold alot of weight or hold boards in place. Anyone who has built houses knows that a hilti gun makes your life alot easier. So, not all explosives are made to destroy some have been used and refined to assist in the building proces. This works in the same concept as a potato cannon which are fun to build and give great experience in enginering and safe exlosives. We all know that it is easier to destroy something than destroying somthing. I would much rather build.
