CHAPTER 2 - THE SPARK TEST


THERE IS ONLY ONE VIABLE WAY TO DEMONSTRATE WEATHER A PIECE OF ROCK (AGGREGATE) IN A CONCRETE SLAB IS HELD IN PLACE WELL, AND THAT IS BY HITTING THE CONCRETE SLAB WITH A HEAVY METAL OBJECT SUCH AS A HEAVY FLAT HEAD SCREWDRIVERS METAL TIP END. NOT THE SMALL SCREWDRIVER YOU HAVE IN YOUR DRAWER, THE HEAVY FOOT LONGS THEY SELL AT THE HARDWARE STORE. IF YOU STRIKE THE FLOOR AT A DOWNWARD ANGLE WITH THE METAL TIP OF THE FLAT HEAD SCREWDRIVER HARD ENOUGH YOU SHOULD BE ABLE TO SLIGHTLY GOUGE OR CHIP THE CONCRETES TOP SURFACE. IF THE ROCK INSIDE THE CONCRETE IS HELD TOGETHER WELL THEN THE ROCK WILL CHIP (PRODUCING A SPARK). IF THE CEMENT PASTE THAT HOLDS THE ROCKS TOGETHER IS NOT HELD TOGETHER WELL THEN STRIKING THE ROCK WILL BRAKE IT AWAY FROM THE CEMENT WITHOUT CHIPPING THE ROCK, THUS NOT CREATING A SPARK. IF THE FLOOR DOES NOT PRODUCE A SPARK IT IS BECAUSE THE CONCRETE IS DEFICIENT. IF STRIKING THE FLOOR DOES PRODUCE A SPARK THEN IT PASSES THE TEST.
