摘要

The objective of this article is to describe the current state of the cement industry, its sustainability, and how it compares to alternative cement technologies-specifically Sialite technology. The process for creating the most widely used cement, portland cement, is an energy intensive process, which consumes considerable natural resources, such as limestone. In addition, portland cement production releases harmful air pollutants, detrimental to human respiratory health, and also emits significant quantities of carbon dioxide. The cement industry will not be sustainable in its current state. A new process for creating cement is necessary, which requires less energy, less use of natural sources, and emits less air pollution. Sialite technology is a new technology based on earth science that simulates natural rock formation. Sialite may lead to a more sustainable cement industry as it requires less energy to produce, has an abundant source of natural resources, and emits less to almost no pollution compared to portlandrncement. In addition, other technologies are presented for cement industry sustainability.
