The most common cause of spalling is errors on the part of contractors. They either add additional water to the concrete as they finish it or they start to finish the concrete before the concrete bleed water leaves the surface of the concrete.

How long does it take for cement to crumble?
Modern concrete—used in everything from roads to buildings to bridges—can break down in as few as 50 years.
Why is my cement brittle?
Plain concrete is brittle because it has low tensile strength. Innately, this mechanical property of concrete (just like any building materials) depends on the synergistic contribution of its components which are water, cement, and aggregate.
What makes concrete driveways flake?
When the temperature drops below freezing, moisture in the concrete tends to expand, creating internal pressure. Over the course of a winter, or over the course of years, as the internal pressure rises and falls, it stresses the surface layer of the concrete, which leads to spalling.
Why Does Concrete Flake?
Why is my concrete brittle?
Plain concrete is brittle because it has low tensile strength. Innately, this mechanical property of concrete (just like any building materials) depends on the synergistic contribution of its components which are water, cement, and aggregate.
How long should a concrete driveway last?
25 to 30 years.
What is it called when concrete crumbles?
Spalling is usually defined as the disintegration of the upper surface of a concrete slab. In most cases this failure extends down about 1/4 inch or less. When the upper finished surface of the concrete crumbles, you end up seeing the rougher stone aggregate that's a part of most concrete slabs.

How do you stop concrete from flaking?
Sealing is the best way to prevent moisture-related spalling. For new concrete, apply a penetrating waterproofing sealer 28 days after concrete placement and every few years thereafter. The correct concrete mix can also help prevent spalling.
Is a concrete driveway worth it?
The combined strength and longevity make concrete a relatively good value for large areas of paving. As a driveway surface, concrete is more expensive than gravel and asphalt, but it is considerably less expensive than a driveway made with brick, cobblestone, or concrete pavers—and it typically outlasts all of these.

Why is my new cement crumbling?
If too much water is introduced to the mixture, the cement and sand cannot bond with each other and will instead fall apart. As the concrete starts to dry, this results in a crumbling area where the particles aren't sticking together.
Why is my concrete driveway cracking?
Concrete is made up of cement and water. As the concrete hardens and the water evaporates, the concrete shrinks. Too much water will lead to too much shrinkage, causing the concrete to crack. That's why concrete cracks are frequently seen within the first 30 days.
