Rock - Excavability
Brief Description
The excavability of rock depends
mainly on the rock strength and the
layer thickness. This diagram shows
excavation methods for rock of
various strengths and thicknesses,

Trial Grouting of Post-tensioning Duct
ⓒ David H Moloney
Brief Description
The full-scale trial of grouting operation shall
demonstrate/document that all requirements to the grout and the
execution of the work are fulfilled simultaneously using the actual
methods and performed by personnel as for the future production.
Pre-trials were carried out in the site laboratory and by way of a
mock-up to check the following in accordance with BS EN 447:
i Fluidity
ii Bleeding and re-absorption
iii Compressive strength (3 cubes at 28 days, all > 30 N/mm2)
iv Mixing ratio (w/c < 0.40)
v Expansion (-1 % - +5 %). For grouts with expanding admixtures
