Moisture Resistance in Open Cell Blocks: What You Need to Know
Moisture Resistance in Open Cell Blocks: What You Need to Know
| Step | Action | Novel Insight | Risk Factors |
|---|---|---|---|
| 1 | Understand the concept of water absorption | Open cell blocks have high porosity, which means they can absorb water easily. | If the open cell blocks are not properly installed or sealed, they can absorb water and cause damage to the structure. |
| 2 | Consider vapor permeability | Open cell blocks have high vapor permeability, which means they allow moisture to pass through them easily. | If the open cell blocks are used in areas with high humidity, they can absorb moisture and cause damage to the structure. |
| 3 | Evaluate hydrophobicity | Open cell blocks can be treated with hydrophobic materials to make them water repellent. | If the hydrophobic treatment is not applied properly, the open cell blocks can still absorb water and cause damage to the structure. |
| 4 | Understand capillary action | Open cell blocks can absorb water through capillary action, which is the ability of a liquid to flow in narrow spaces without the assistance of, or in opposition to, external forces like gravity. | If the open cell blocks are not properly installed or sealed, they can absorb water through capillary action and cause damage to the structure. |
| 5 | Consider efflorescence | Open cell blocks can experience efflorescence, which is the white powdery substance that appears on the surface of masonry materials due to the migration of soluble salts. | If the open cell blocks are exposed to water, the soluble salts can migrate to the surface and cause efflorescence, which can weaken the structure. |
| 6 | Evaluate mold growth and fungal decay | Open cell blocks can provide a suitable environment for mold growth and fungal decay if they are exposed to moisture. | If the open cell blocks are not properly installed or sealed, they can absorb moisture and provide a breeding ground for mold and fungi, which can cause health problems and weaken the structure. |
| 7 | Consider corrosion resistance | Open cell blocks can be made with materials that are resistant to corrosion, which is the deterioration of a material due to chemical reactions with its environment. | If the open cell blocks are exposed to corrosive materials or environments, they can deteriorate and weaken the structure. |
| 8 | Evaluate durability | Open cell blocks can be durable if they are properly installed and maintained. | If the open cell blocks are not properly installed or maintained, they can deteriorate and weaken the structure. |
| 9 | Consider water repellency | Open cell blocks can be treated with water repellent materials to prevent water absorption. | If the water repellent treatment is not applied properly, the open cell blocks can still absorb water and cause damage to the structure. |
| 10 | Evaluate air flow rate | Open cell blocks can provide good air flow rate, which is the rate at which air can pass through a material. | If the open cell blocks are used in areas with high air flow, they can allow too much air to pass through and affect the temperature and humidity levels inside the structure. |
| 11 | Consider thermal conductivity | Open cell blocks can have low thermal conductivity, which means they can provide good insulation. | If the open cell blocks are used in areas with high temperature fluctuations, they can affect the temperature and humidity levels inside the structure. |
| 12 | Evaluate fire resistance | Open cell blocks can have good fire resistance if they are made with fire-resistant materials. | If the open cell blocks are exposed to fire, they can deteriorate and weaken the structure. |
In summary, open cell blocks have high porosity and vapor permeability, which means they can absorb water easily. However, they can be treated with hydrophobic materials to make them water repellent. Open cell blocks can also absorb water through capillary action and cause damage to the structure if they are not properly installed or sealed. They can also experience efflorescence, provide a breeding ground for mold and fungi, and deteriorate if they are exposed to corrosive materials or environments. Therefore, it is important to evaluate the durability, air flow rate, thermal conductivity, and fire resistance of open cell blocks before using them in a structure.

Common Mistakes And Misconceptions
| Mistake/Misconception | Correct Viewpoint |
|---|---|
| Open cell blocks are always non-load-bearing. | Open cell blocks can be load-bearing or non-load-bearing depending on their density and strength. It is important to consult with a structural engineer or building code requirements to determine the appropriate use of open cell blocks in construction. |
| Load-bearing open cell blocks have lower insulation value than non-load bearing ones. | The insulation value of open cell blocks depends on their density, not whether they are load-bearing or non-load-bearing. Higher density open cell blocks generally provide better insulation than lower density ones regardless of their load capacity. |
| Non-load bearing open cell blocks cannot support any weight at all. | While it is true that non-load bearing open cell blocks cannot support significant weight, they can still provide some structural stability and resistance to lateral forces such as wind or earthquakes when used in combination with other building materials like steel framing or reinforced concrete columns and beams. |
| Load-bearing open-cell block walls require additional reinforcement for seismic loads compared to traditional masonry walls. | Load-Bearing Open-Cell Block Walls do not necessarily require additional reinforcement for seismic loads compared to traditional masonry walls if designed properly by following the local building codes and standards set forth by the authorities having jurisdiction (AHJ). However, it is recommended that a licensed professional engineer review the design before construction begins. |
