Environmental concerns regarding the production of cement particles in terms of energy
consumption and CO2 emission resulted in to conduct widely studies for more environmentally
viable alternatives. One of these alternative solutions is to use alkali-activated binder which is
produced using industrial by-products containing silicate materials. Geopolymeric binders are the
latest types of inorganic binders which use alkaline activation of wastes such as slag or fly ash. The
geopolymerization of alumina-silicate materials is a complex chemical process evolving dissolution
of raw materials, transportation, orientation and polycondensation of the reaction products. Classical
two part geopolymers could become more eco-efficient with a lower CO2 footprint if sodium
silicate usage is avoided. Besides current geopolymeric mixes can suffer from efflorescence
originated by the fact that alkaline or soluble silicates that are added during processing cannot be
totally consumed during geopolymerisation. Therefore, new and improved geopolymer mixes are
needed. One-part geopolymers (sodium silicate free) were proposed in 2008. Up to now a lot of
issues remain unexplained about them. Thus this study was assigned to investigate the durability
performance of one-part geopolymers. The tests made comprise water absorption, penetration of
chloride, carbonation, acid attack.
