ABSTRACT

The cement production sector is one of the very high energy-intensive and polluting industries in the world economy, although demand for Portland cement is constantly growing worldwide.

When clinker is fired as a result of limestone decarbonization, a huge amount of greenhouse gases, mainly CO2 , is released into the atmosphere, which accounts for about 8% of all global emissions. Therefore, any reduction in the use of clinker will have a major impact on global warming. To achieve this goal, new technologies for obtaining clinker-free binders are being developed, one of which is geopolymer materials.

Geopolymer materials (GPM) can become an alternative to Portland cement (OPC), as carbon emissions are reduced by about 80%. In addition, given that geopolymer concretes are generally stronger and more durable, they offer a longer service life, which reduces the need for raw materials in the time ahead.

For the widespread use of geopolymers in the construction industry, it is necessary, along with other properties, to study their durability.

This chapter describes the technology for obtaining geopolymer materials using thermally modified polymineral clay rocks and assessing their durability. Studies have shown that geopolymer materials have good durability and higher resistance to aggressive solutions compared to OPC.
