Turbhe -2022

Problem: –

• First to third floor was damage due to fire.
• Temperature during fire was 600⁰C.
• Due to high temperature, surface of concrete is highly carbonated.
• Micro cracks can be observed on the RCC elements.

Solution :-

• The entire exposed concrete surface was chipped and replaced.
• Column was jacketed with additional steel and Micro-concrete.
• Slab was supported with additional structural steel members.
• Entire external plaster was chipped and replaced with new plaster.

MARQUARDT

20021-2022

Problem

• Low concrete strength (10 MPa) and inadequate axial load capacity was observed
• Additional strong room load over the columns
• Corrosion damages were observed
• Being a heritage structure, no demolition work was allowed.

Solution:

• RCC members were treated for corrosion damages and polymer modified mortar was used to rebuild sections.
• Axial load carrying capacity of circular columns was increased using multiple layers of GFRP.
