A fresh set every day. Short, practical, and written the way it actually matters on site.
Screed
A thin levelling layer laid over a structural slab.
On siteIt provides the falls and the flat plane the final floor finish needs.
Setting Out
Transferring the drawing's geometry onto the ground.
On siteErrors here are the most expensive on any project, because everything built afterwards inherits them.
Fly Ash
A fine residue from coal combustion used to replace part of the cement.
On siteImproves long-term strength and cuts heat of hydration, but slows early strength gain.
Heat of Hydration
Heat released by the chemical reaction between cement and water.
On siteIn thick pours the core heats far more than the surface, and the resulting gradient cracks the member.
Lap Length
The overlap between two bars so force passes from one to the other.
On siteLaps belong in low-stress zones. Lapping every bar at the same section creates a deliberate weak plane.
