Concrete is one of the most commonly used building materials for both commercial and residential purposes. The efficacy of this material depends mostly on the moisture levels contained in the mix. The perfect mix of water and cement is required to get a durable surface, but too much moisture can be problematic, as Builder’s Concrete East explains. As Windham, CT’s leading concrete supplier, they understand the structural deficiencies that an overly wet mix can produce.

How Moisture Affects Concrete

Decreased Strength & Durability

ConcreteCompaction is necessary for a solid and stable concrete surface. Too much water creates gaps between the aggregate materials, making it more difficult to compact the mix. With wider gaps in the aggregate, the cement will demand more water, which increases the water to cement ratio and makes the final product prone to cracks and shrinkage. 

Sweating Slab Syndrome

Excess humidity can cause moisture to intermittently develop on the surface of the concrete, producing a phenomenon known as sweating slab syndrome. Commonly found on indoor slabs, it results in a slippery surface that can pose a safety hazard to pedestrians or heavy machinery operators attempting to drive across the slab. Dew point condensation can also cause sweating slab syndrome. If the temperature of the slab is at or below the dew point, water will condense on the surface of the concrete, making it slippery.

Excess moisture in concrete can lead to an unstable surface and pose serious safety risks.
