By The Guardian Chief Technical Advisor — GUGAFIX® Construction Chemicals Introduction Structural rehabilitation is not simply the repair of damaged concrete. It is a complete engineering process that begins with understanding the existing structure and ends only when the repaired or strengthened structure has been properly inspected, documented and handed over. A cracked beam may need repair. A deteriorated column may need concrete restoration. A structurally inadequate mem

By The Guardian Chief Technical Advisor — GUGAFIX® Construction Chemicals Introduction There is rarely one universal method for strengthening an existing RCC structure. When a beam, column or other structural member requires strengthening, engineers may consider several approaches, including: Concrete jacketing Steel plate strengthening Fiber Reinforced Polymer (FRP) systems Each method has different characteristics. The right choice depends not simply on which material is s

By The Guardian Chief Technical Advisor — GUGAFIX® Construction Chemicals Introduction When an RCC beam develops inadequate load-carrying capacity, excessive cracking, deterioration, or increased loading requirements, strengthening may be necessary. Concrete jacketing and steel plate strengthening are established methods, but they can increase member size, add considerable dead load, require extensive access and involve significant site work. Fiber Reinforced Polymer (FRP) s

A Practical Guide to Assessing, Designing and Executing Concrete Jacketing for Existing RCC Beams By The Guardian Chief Technical Advisor GUGAFIX® Construction Chemicals gugafix.com/post/rcc-beam-strengthening-concrete-jacketing Introduction Concrete jacketing is one of the established methods used for strengthening existing reinforced concrete beams. The basic concept is straightforward: An existing RCC beam is enlarged by adding new concrete and additional reinforcement so

When Repair Is Not Enough and the Beam Needs Additional Structural Capacity By The Guardian Chief Technical Advisor GUGAFIX® Construction Chemicals An RCC beam can deteriorate for many reasons. It can also become structurally inadequate for reasons that have nothing to do with visible deterioration. For example: Building use may change Loads may increase Original design may have deficiencies Reinforcement may have deteriorated Structural modifications may alter load paths New

A Strengthening System Is Only as Good as Its Design, Detailing and Execution By The Guardian Chief Technical Advisor GUGAFIX® Construction Chemicals Concrete jacketing is one of the established approaches that may be considered when an existing RCC column requires structural strengthening. But jacketing is not simply a matter of making a column bigger. The enlarged section, reinforcement arrangement, connection with the existing column, load transfer and construction sequenc

Structural Repair vs Structural Strengthening: What Is the Difference? Two Different Objectives That Can Sometimes Be Part of the Same Rehabilitation Project By The Guardian Chief Technical Advisor GUGAFIX® Construction Chemicals Repair and Strengthening Are Not the Same Thing A damaged RCC column may need concrete reinstatement. But that does not automatically mean the column needs strengthening. Likewise, a structure may require strengthening even when there is little visi
