Other cementitious elements, for example fly ash and slag cement, are sometimes added—either pre-blended With all the cement or right being a concrete element—and become a Component of the binder for that aggregate.[forty two] Fly ash and slag can enrich some properties of concrete for instance clean Qualities and durability.[forty two] Alternatively, other materials can even be utilised as being a concrete binder: probably the most commonplace substitute is asphalt, that is applied as the binder in asphalt concrete.
No matter if you’re wanting to established a whole new walkway, restore an existing composition or tackle a DIY task, The house Depot has each of the concrete, asphalt maintenance and masonry equipment you have to get the job carried out appropriate.
