A fresh set every day. Short, practical, and written the way it actually matters on site.
Compaction
Mechanically packing soil to raise its density by expelling air.
On siteAchieved against a Proctor test maximum dry density. Under-compacted fill shows up later as settled floors.
Creep
Slow, continued deformation under a sustained load.
On siteLong-span beams keep deflecting for years after casting, which is why long-term deflection is checked separately.
Angle of Repose
The steepest natural slope loose material holds without sliding.
On siteIt governs safe excavation batter. Cutting steeper than this is how trench collapses kill people.
Rebar Grade
The yield strength class of reinforcing steel, such as Fe415 or Fe500.
On siteHigher grade means less steel for the same moment, but development and lap lengths get longer.
Negative Skin Friction
Downward drag on a pile when surrounding soil settles more than the pile does.
On siteIt adds load instead of resisting it — a real hazard for piles driven through recent fill.
