History of fiber cement sheets production
Fiber cement sheets are consisted of cement and reinforcement fibers and are one of the modern buildings requirements.
- As cement became popular in building industry as well as its extensive use, cement facades became very popular as well.
- Since the invention of pre-constructed buildings the idea of fiber cement sheets became stronger because it could be produced at the factory and delivered to the project site to be installed.
- Considering the weakness cement has in bending and tension strength, the idea of reinforcing it was always discussed. In the late 19th and early 20th century an Austrian engineer by the name of Ludwig Hatschek used asbestos fibers to reinforce cement and build a machine modeled after the paper production machine which injected regular dosses of asbestos to cement dough and produced an excellent material with exemplary qualities by the name of flat asbestos sheets or corrugated cement sheets which was produced and used in all countries for the past century.
- Since the last decay of 20th century, considering health and environmental factors, the ban of asbestos use was instructed in international communities. Fiber cement producers decided to find a substitute for asbestos. The result of the researches by the name of N.T (new technology) was launched and asbestos-free fiber cement sheets were produced.
Fiber cement sheets or boards are produced by Hatschek and the most important difference between them and the old production method is in the materials used, the processing and the technical science involved.
