Abstract:

Specification for shotcrete specifies control over slump, time lag between batching and placing, compressive strength, shotcrete thickness, density and permeability. The wet-mix shotcrete is required to have quality control over the workability for easy pneumatic placement, minimum rebound and good compaction. This paper reports the quality assurance experience gained from a project involving 2700 cubic metre of shotcrete, during the construction of 35 km long Southern Sydney Freight Line project, lasted over 3 years. The field experience showed that quality assurance specification for shotcrete mix must be followed to ensure the quality of placed shotcrete.
