A fresh set every day. Short, practical, and written the way it actually matters on site.
Slump Test
Measuring how far a moulded cone of fresh concrete subsides.
On siteThe quickest workability check on site, and the fastest way to catch an over-watered load.
Cohesion
Shear strength that exists in a soil even with no confining pressure.
On siteClay has it, clean sand has almost none — which is why sand needs shoring and stiff clay may stand briefly.
Core Cutting
Extracting a cylinder of hardened concrete for testing.
On siteThe fallback when cube results fail, since it measures the concrete actually in the member.
Shear Force
Internal force acting parallel to a section, trying to slice it.
On siteIt peaks at supports, which is exactly where stirrups are tightened up.
Workability
How easily fresh concrete can be mixed, placed and compacted without segregating.
On siteMeasured by slump. Adding water on site to improve it is the most common way good mixes are ruined.
