Cement is a type of binder used in the construction industry to connect composite materials such as sand, gravel and water for the purpose of making materials used in construction. The main function of cement is to create a solid joint between the components of composite materials for construction, which then serve to form structural elements such as foundations, columns and walls. The history of cement goes back thousands of years. In Croatia, cement production developed during the 20th century. Cement factories, such as the factory in Rugvica near Zagreb, played an important role in the development of the construction industry and infrastructure in the country. The largest cement companies in Croatia are CEMEX Hrvatska d.d., NEXE group and Holcim d.o.o.. The Croatian cement industry today produces different types of cement and special types of cement with different properties. Sustainable cement production is a concept that is increasingly prominent in the construction industry. The production of traditional cement usually generates significant amounts of greenhouse gases such as carbon dioxide (CO2) and others, and in this way contributes to the reduction of emissions, the processing of waste building materials that are reused and ultimately the preservation of the environment. Although cement has its role in the production of concrete and cement mortar, and contributes to their final strength, the choice of aggregates in the cement mixture has the greatest impact on their final strength, breakdown force and the time period from the moment of application of force to the moment of breakdown, which is proven by laboratory testing according to HRN EN 196-1 on the train (bending) and pressure.
