Sialite technology—sustainable alternative to Portland Cement
Clean Technologies and Environmental Policy, 2010Co-Authors: Henghu Sun, Kennedy Nguyen, Ravi Jain, John ZuckermanAbstract: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 Portland Cement. In addition, other technologies are presented for Cement industry sustainability.

blended Cements consisting of Portland Cement slag silica fume metakaolin system
Journal of Thermal Analysis and Calorimetry, 2016Co-Authors: Eva Kuzielova, Frantisek Soukal, Radoslav Novotný, Martin Palou, Matus žemlickaAbstract:In the present study, hydration of four-compound systems consisting of Portland Cement and three supplementary Cementitious materials : silica fume, blast-furnace slag, and metakaolin, has been investigated by means of isothermal calorimetry and thermal analysis. Substitution of Portland Cement was achieved at 25, 30, and 35 mass% by Cementitious supplementary materials. Owing to the high specific surface, the silica fume eventuated in more distinctive demonstration of pozzolanic reactions. It decreased C/S ratio and led to the formation of hydration phases with C/S ≅ 1, which is demonstrated by wollastonite crystallization at higher temperatures. Enhanced formation of gehlenite hydrate was proved by DTG when blended Cements included higher content of metakaolin and blast-furnace slag. Pozzolanic materials increased the compressive strength of particular blended samples and thus overcame the dilution effect especially at long term of curing. Presented quaternary blended samples in comparison with ordinary Portland Cement thus allowed the formation of more thermal stable hydration products and can be considered as promising materials for the development of special concrete also for hydrothermal applications.
