Abstract

Procedure for the manufacture of railway sleepers with overlapping sheets of asbestos-cement, characterized in that the working pressure is not brought above 300 kg/cm2 at all and said pressure is reached in a maximum time absolutely less than 5 minutes, in such a way that the material is not dehydrated too much, keeping the optimum of water for the correct setting of the cement (Machine-translation by Google Translate, not legally binding)
