Sažetak
It is now more obvious than ever that the only option for the development of the built environment is a sustainable and environmentally responsible one. In the field of building materials, especially in concrete technology, there are many studies that deal with alternative raw materials, such as by- products, recycled materials or natural resources that are not fully exploited. However, with the alternative materials, alternative durability challenges may also arise. More so, some of the known durability challenges may re-emerge in alternative forms. Alternative materials have different chemical and physical properties compared to a classical system. Different reaction products, different pore structure, electrical resistivity or tortuosity of the pores can lead to different behaviour of the materials and their degradation mechanisms. To predict and control the durability of alternative materials in the environment, a complete understanding of their microstructure is of utmost importance. In the present work, some examples of developed alternative binders based on local materials are presented. Among others, binders based on high cement replacement, binders based on calcium aluminate and alkali-activated binders are discussed. Among the degradation mechanisms, chloride penetration, corrosion and carbonation and their specific mechanisms with alternative binders are addressed.
