Study explores how boron oxide (B2O3) can stabilize high-ferrite Portland cement clinker during low-temperature calcination.
The research examines the effect of boron oxide as a stabilizing agent for high-ferrite Portland cement (HFPC) clinker during low-temperature calcination, highlighting its advantages over other stabilizers.
Conducted by Xiao Huang, Jinfang Zhang, and Kechang Zhang; published by the authors of the article.
Study completed prior to its publication on date; study date not explicitly indicated.
The research does not specify any location for the laboratory tests and analysis.
The study is motivated by the need to reduce carbon dioxide emissions from cement production, which accounts for approximately 8% of global CO2 emissions. The focus is on creating more energy-efficient cement production methods.
The research methodology included the use of different stabilizing agents, including boron oxide, and evaluated its impacts on the stability and hydration behavior of HFPC clinker through various tests such as X-ray diffraction (XRD) and hydration heat analysis.
The study concludes B2O3 should be limited to below 1% to prevent compromising strength development.
"The cause of HFPC clinker pulverization at 1350 °C is due to the C2S phase formed being metastable."
"B2O3 is chosen as the best stabilizer for the low-temperature calcination of HFPC clinker."
"The introduction of B2O3 leads to slow early strength development but eventually shows excellent compressive strength."
