Why Are Concrete Roof Slabs on GIS Buildings Prone to Premature Cracking<\/span><\/span><\/strong> ?<\/span><\/span><\/p>\n

A Standards-Based Engineering Approach and Field Practices: Premature cracking in concrete roof slabs remains a common finding in Gas Insulated Substation (GIS) construction projects, even in designs that meet standards. While generally non-structural, this condition cannot be ignored because it has the potential to affect durability, increase the risk of leaks, and impact the building’s long-term performance.<\/span><\/span><\/p>\n

In practice, cracking is often directly attributed to natural concrete properties such as shrinkage. However, field experience shows that the causes are not that simple. A more comprehensive understanding is needed, linking design, construction methods, and environmental conditions.<\/span><\/span><\/p>\n

Roof characteristics of GIS buildings<\/span><\/span><\/strong><\/p>\n

Roof slabs on GIS buildings have a relatively high level of exposure compared to conventional buildings. Roof surfaces generally receive direct solar radiation throughout the day, with limited protection from shading elements.<\/span><\/span><\/p>\n

This condition causes significant temperature fluctuations, with the upper portion of the slab experiencing intense heating while the lower portion is relatively stable. This difference is a major factor in triggering internal stresses in concrete, especially in <\/span><\/span>
\nits early stages.<\/span><\/span><\/p>\n

Understanding the Causes of Cracks More Comprehensively<\/span><\/span><\/strong><\/p>\n

Shrinkage Is Not The Only Factor<\/span><\/span><\/strong>
\n In reinforced concrete design, shrinkage crack control has been regulated through the provision of minimum reinforcement according to SNI 2847:2019 which refers to ACI 318. However, this approach basically assumes that the implementation conditions run according to the design assumptions, especially in terms of curing.

Curing: A Critical Factor That’s Often Overlooked<\/span><\/span><\/strong>
\n Curing plays a crucial role in maintaining concrete moisture and ensuring optimal hydration. According to ACI 308R, failure to cure can accelerate water loss from the concrete surface. In field conditions, some common occurrences include:<\/span><\/span><\/p>\n
