Advancements in Sand Casting
In 1924, the Ford automobile company set a record production of 1 million cars, consuming the casting industry.
Experiments were conducted with types of clay to improve strength in molding sand, updating cupola furnaces to electric and moving the traditional foundry to a factory setting improved process.
Now, sand casting is a fully automated factory system.

Geosynthetic products of natural material

Although most of the geosynthetics are made from synthetic polymers, a few specialist geosynthetics, especially geotextiles, may also incorporate steel wire or natural biodegradable fibres such as jute, coir, paper, cotton, wool, silk, etc.
Biodegradable geotextiles are usually limited to erosion control applications where natural vegetation will replace the geotextile’s role as it degrades. Jute nets are marketed under various trade names, including geojute, soil saver, and anti-wash.
They are usually in the form of a woven net with a typical mesh open size of about 10 by 15 mm, a typical thickness of about 5 mm and an open area of about 65%.
Vegetation can easily grow through openings and use the fabric matrix as support. The jute, which is about 80% natural cellulose, should completely degrade in about two years. An additional advantage of these biodegradable products is that the decomposed jute improves the quality of the soil for vegetation growth.
