A step-by-step guide to installing epoxy-bonded (adhesive) anchor bolts in RCC framing, covering ACI 318-19 Chapter 17 design basics, ACI 355.4 qualification, the drill-clean-inject-insert procedure, cure/torque, and installer certification and special inspection requirements.
The mathematics behind concrete mix design — the absolute volume equation, Abrams’ law, target mean strength and moisture correction — with three complete hand calculations: an M25 mix to IS 10262:2019, a 30 MPa mix to ACI 211.1, and a nominal 1:1.5:3 quantity take-off.
Prestressed concrete uses tensioned steel tendons to put the section into compression before loading, extending spans and reducing cracking. Pre-tensioning vs post-tensioning, tendon profiles, reading prestress drawings, and common applications explained.
Ductile detailing under IS 13920 ensures RCC frames survive earthquakes by deforming without collapsing. The principles of confinement, strong column-weak beam, and the specific rules for beam, column, and joint detailing explained clearly.
Shear walls resist the lateral forces from wind and earthquakes in concrete buildings. How they work, where to place them for torsional balance, how they are reinforced, what boundary elements and coupling beams do, and how to read shear wall details.
