TL;DR: In this paper, the authors established an input-output model on cement plants and calculated carbon dioxide emissions of key steps and carbon footprint of products using the input output model and showed that CO2 emission in the plant (the production of the plant is 1320000t a year) reached 910000 t a year and CO2 emissions per ton product is 0.689 ton.
Abstract: Input-output model on cement plants were established. Carbon dioxide emissions of key steps and carbon footprint of products were calculated and predicted using the input-output model. The results showed that CO2 emission in the plant (the production of the plant is 1320000t a year) reached 910000 t a year and CO2 emission per ton product is 0.689 ton. Over 80% of the total CO2 was emitted during the process of firing，so the firing process is the key step for reducing CO2 emission in the cement plant. Carbon footprint of three kinds of cement products including ordinary portland cement, portland pozzolan cement and portland blast furnace slag cement are 0.76, 0.59, 0.72 respectively.

TL;DR: In this article, a carbon measuring model is established and used to calculate carbon dioxide emissions from key processes and carbon footprint of products and several solutions are proposed to reduce CO2 emission from these two processes and substituting coal with natural gas seems to be the most efficient way.

TL;DR: In this article, the authors compared the performance of AAS concrete and low calcium fly ash geopolymer (FAGP) concretes up to 540 days and found that AAS had higher compressive and tensile strength, elastic modulus and lower permeation characteristics than FAGP concrete.

TL;DR: In this article, the workability of a geopolymer was investigated and the negative zeta potential of fly ash was identified as assisting gel formation with the smaller the negative zero potential of the fly ash, the more gel formation and high compressive strength observed.
