Splet01. maj 2014 · Engineered Cementitious Composite (ECC) shotcrete is a cement composite that is reinforced with synthetic fibers. When loaded in tension, ECC exhibits a strain-hardening characteristic through the process of micro-cracking, where stresses are taken up by fibers that bridge the cracks. SpletShotcrete is applied either as a wet mix or dry mix with water added at the nozzle. The wet mix process has the capability of placing either mortar or concrete. For concrete, the material will normally be delivered to the site by ready-mix truck or mixed at the site in a concrete mobile mixer.
