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.
Development Length
The bar length needed to transfer its full stress into the surrounding concrete.
On siteLd = (0.87·fy·φ)/(4·τbd) per IS 456. Short-anchored bars pull out before the steel ever yields.
Screed
A thin levelling layer laid over a structural slab.
On siteIt provides the falls and the flat plane the final floor finish needs.
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.
Moment of Inertia
A section's geometric resistance to bending.
On siteIt scales with depth cubed, which is why a beam laid on edge is dramatically stiffer than the same one laid flat.
