A fresh set every day. Short, practical, and written the way it actually matters on site.
Stirrups
Closed loops of steel tying the main bars and resisting shear.
On siteThey are spaced closest near supports, where shear peaks — not uniformly along the beam.
Shuttering
The temporary mould that holds concrete until it can hold itself.
On siteStripping it too early is a leading cause of sagging slabs and permanent deflection.
Bond Stress
Shear stress at the interface between a bar and the concrete gripping it.
On siteDeformed bars develop roughly 60% more bond than plain bars, which is why IS 456 allows a shorter Ld for them.
Balanced Section
A section where concrete crushes and steel yields at the same instant.
On siteDesigners deliberately stay under-reinforced so steel yields first and the member warns before it fails.
Water–Cement Ratio
The mass of water divided by the mass of cement in a mix.
On siteLower it and strength rises but workability drops. It is the single strongest lever you have over concrete strength.
