The reaction normally takes place when subjected to h2o and un-hydrated cement particles to form insoluble needle-shaped crystals, which fill capillary pores and micro-cracks in the concrete to block pathways for drinking water and waterborne contaminates.
Other cementitious elements, like fly ash and slag cement, are sometimes added—either pre-blended with the cement or right to be a concrete component—and become a Section of the binder for the combination.[forty two] Fly ash and slag can enhance some Qualities of concrete including clean Attributes and durability.[42] Alternatively, other components can be applied for a concrete binder: the most prevalent substitute is asphalt, that is applied as the binder in asphalt concrete.
