Increasing utilization of secondary raw materials and alternative fuels results in increasing contents of metals in cements. Zinc is one of these elements. It comes to cement with secondary raw materials such as slag or fly ash or by the utilization of used tires as an alternative fuel.

- This study examines how zinc influences the hydration process of Portland cement, particularly when blended with ground blast furnace slag (GBFS).
- The increase in zinc content in cement is attributed to the use of solid waste and recycled materials, impacting overall cement properties.
- Various forms of zinc were tested in different concentrations, and the hydration process was monitored using isothermal and isoperibolic calorimetry, along with X-ray diffraction to identify new hydration products.
