การจัดการรอยร้าวที่เกิดจากการบรรทุกเกินพิกัดในโครงสร้าง Flat Slab โดยใช้ SmartInjection EP 21

Introduction:
This case study examines the issue of overload-induced cracking in flat slab structures, a common problem in civil engineering. The remediation process employed by Smart and Bright Co. using their proprietary SmartInjection EP 21 epoxy injection technique is evaluated. This method, paired with in-depth crack analysis using Crack width gauge and Ultrasonic tools for depth assessment, provided comprehensive repair solutions

Problem Identification:
flat slab structure under consideration began exhibiting significant cracks due to overload. The overload, beyond the structure’s designed capacity, led to the initiation and propagation of cracks, endangering the structural integrity and safety of the construction.

Crack Analysis:
Before proceeding with the repair work, a thorough analysis of the cracks was undertaken. The Smart and Bright Co. team used a Crack width gauge, a reliable tool to measure the width of the cracks accurately. Further, they used Ultrasonic tools to analyze the depth of these cracks. These two techniques provided a clear picture of the extent of damage and helped formulate a targeted repair plan.

Solution – SmartInjection EP 21:
The repair solution employed was the SmartInjection EP 21, an epoxy-based injection solution designed to fill and seal cracks in concrete structures. The decision to use SmartInjection EP 21 was based on its superior adhesive strength, low shrinkage, excellent moisture resistance, and capacity to restore the structural integrity of the slab.

Implementation:
Under the guidance of the expert team, the SmartInjection EP 21 was prepared and injected into the cracks. The method ensured deep penetration and complete filling of the cracks, which effectively arrested further propagation.

Results:
Following the treatment, the cracks were effectively sealed, restoring the slab’s strength. Post-repair ultrasonic analysis confirmed the penetration and filling of the epoxy injection, demonstrating the efficiency of the SmartInjection EP 21.

Conclusion:
This case study has showcased the efficacy of the SmartInjection EP 21 in treating overload-induced cracks in flat slab structures. The combination of the precise crack analysis tools and the skilled execution by Smart and Bright Co. led to successful structural repair. It further suggests the need for regular structural health monitoring to prevent overload and consequent damage.

Future Research:
The potential for further study lies in exploring the preventative measures against overload-induced cracks and investigating the long-term effects and durability of epoxy injection treatments.
