Thermic Drilling of Concrete and Stone

This problem was first submitted to us in Paris in 1013. The old Tournelle bridge was being demolished, since its arches were too narrow for the river circulation and caused the river to overflow its banks every year. It was suggested that the arches might be broken up more easily by drilling into the stones. Maurice Lebrun
