new technology in producing cement
Cement production Climate Technology Centre &
Energy represents 20% to 40% of the total cost of cement production. The production of cement clinker from limestone and chalk by heating limestone to temperatures above 950°C is the main energy consuming process. Portland cement, the most widely used cement type, contains 95% cement clinker.
New approach suggests path to emissions-free cement
2019-9-16 In the new process, the pulverized limestone is dissolved in the acid at one electrode and high-purity carbon dioxide is released, while calcium hydroxide, generally known as lime, precipitates out as a solid at the other. The calcium hydroxide can then be processed in another step to produce the cement, which is mostly calcium silicate.

Cement Production an overview ScienceDirect Topics
This paper explores the use of process integration techniques to improve the energy efficiency of cement plants, focusing on the dry route cement production and the integration of alternative fuels. Flow sheeting modeling, Pinch Analysis and mixed integer linear optimization techniques are applied to study an existing cement production facility.
Usage of Green Concrete Technology in Civil Engineering
2015-1-1 Unfortunately there is no technology to reduce carbon dioxide emission of clean Portland cement. The exception of this is multicomponent cements which are produced with an addiction of by-products of fossil fuel combustion or metallurgy industry. This are very the same products which can be used to producing geopolymer cements.

Cement Fuels & Technologies IEA
2019-12-4 The direct CO2 intensity of cement production increased 0.5% per year during 2014-18. To get on track with the SDS, a 0.8% annual decline is necessary to 2030. Sharper focus is needed in two key areas: reducing the clinker-to-cement ratio (including through greater uptake of blended cements) and deploying innovative technologies
Future of Cement: Low-Carbon Technologies and
2020-5-15 Heidelberg Cement has discovered an alternative clinker technology called TernoCem. The technology works on an altered chemical composition and lower burning temperatures. The company reports that CO2 output is 30% lower in comparison with conventional clinker and energy consumption can be reduced by around 15% [viii].

Cement Production an overview ScienceDirect Topics
Cement production processes can be categorized as dry, semidry, semiwet, and wet processes depending on the handling of raw material before being fed to the rotary kiln. Nowadays, almost all new plants are based on the dry process and many old wet plants are also remodeled to
Trends and developments in green cement and concrete
2012-12-1 An important pre-requisite for investment in new, low carbon cement technologies, is price stability. This is the silver lining that manufacturers in Qatar and Saudi Arabia can benefit from as a consequence of government subsidies and in the US as a consequence of a combination of a Hurricane Katrina and the economic crisis.
