"Much attention has been paid to the development of small-scale concrete tile production as an affordable alternative to traditional roofing materials such as straw and modern galvanized iron or asbestos cement sheets.These tiles are relatively low Durable (with a shelf life expected to exceed 20 years in most areas), aesthetically acceptable, capable of providing adequate safety and comfort, and provide protection against heavy rain and hot sun.
Concrete tiles are already produced by small businesses in several countries in Africa, South and Central America, Asia and Southeast Asia and in the former Soviet Union. The key to the success of this technology was the development of equipment and techniques to produce small-scale tiles. It typically costs $ 5,000 (excluding land and buildings) to set up a concrete shingle workshop and can be less than $ 1,000 in areas where vibration equipment and molds are made locally. "
