Shotcreting with ecc

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. SpletECC mix indicated that a thickness of 10–15 mm in a single spray could be achieved; therefore, any specified shotcrete thickness in excess of 10 mm was applied successively in overlays of 10 mm, ECC Application Procedures after the previously applied layers had hardened sufficiently.
