Engineering Properties of Shotcrete
Abstract
The important technical information gleaned from a literature survey covering the past 55 years of laboratory and field experiences with mortars and concretes applied pneumatically (i.e., shotcrete) is presented. In addition to general facts concerning this method of construction, various physical properties of hardened shotcrete, which have been investigated by numerous researchers, are discussed. Insofar as strength and elasticity are concerned, hardened shotcrete generally is quite similar to hardened mortar or concrete made in the conventional manner and fully compacted. An experimental program is recommended for (1) developing supplementary data with regard to density, elasticity, and strength (bond, compressive, and flexural) of hardened shotcretes (premixed wet) made with 3/4-inch as well as 3/8-inch maximum-size aggregate, and (2) ascertaining whether or not comparatively small prismatic test specimens truly represent the engineering properties of hardened shotcrete in large wall panels.
