Cement production is one of the industrial sectors that produce a significant share of CO2
emissions. One way to reduce these emissions is to limit cement consumption through the
wider use of blended cement containing pozzolanic active materials from local sources. From a technological standpoint, this presents a relatively straightforward solution to this urgent issue, but unfortunately, most blended cements have low initial strength, which hinders their
competitiveness with traditional composites with higher levels of clinker. Achieving higher
strength requires an understanding of the chemical processes occurring in the initial stage of
cement hydration. The main aim of this project is to understand the influence of innovative
additives (on Ca(HCOO)2, Na2CO3 basis) and nanomaterials (nano-SiO2, -ZnO, -Al2O3) on
the initial strength of cement and the early hydration of cement from both micro and
macroscopic perspectives. The findings may contribute to the design and optimization of the
initial properties of blended cements, which will be increasingly utilized in the future.
