Many new technologies to enable substitution of cement with lower carbon substitutes, such as chemical or mechanical activation of fly ash and other pozzolans, carbon burn-out technologies, alkali-activated alumino-silicates, magnesium-based cements, or carbonation, are harmstrung by one or more of the following drawbacks:

 

• complex implementation that calls for a sharp increase in quality control efforts or substantial training of users of the product 

• only moderate improvements in overall cement substitution levels, or loss of performance as a trade-off for increased cement substitution

• lack of standards, industry practices and know-how for the market to quickly adopt the new technology

• massive upfront capital needs that fatally affect the return on investment 

 

Most of the time, this translates into either very modest financial benefits to users of the new technology, or a much less significant reduction in CO2 emissions.

 

Roman Cement is different. The application of the Roman Cement technology imparts both significant financial and environmental benefits.
