Abstract:

This paper presents some theoretical considerations for studies on high performance wet-mix shotcrete. A new laboratory shotcrete pump and rheometer are being developed to study the effects of aggregate gradation, cement type, air content, silica fume, superplasticiser and fibers on the rheological properties of wet-mix shotcrete.
