Aggregate Absorption

Aggregate Absorption (Desportion) The second key issue in providing internal curing via saturated lightweight aggregates is how much of the water contained in the aggregates is readily available to migrate to the hydrating cement paste during the curing process.

Concrete

Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens (cures) over time. Concrete is the second-most-used substance in the world after water, and is the most widely used building material. Its usage worldwide, ton for ton, is twice that of steel, wood, plastics

What Is Concrete Spalling

What Is Concrete Spalling? The phenomenon in which Concrete Surface undergoes flaking or peeling near the surface portion of the finished slab, which may further extend to the top layer of reinforcing steel is known as Concrete Spalling.Spalling occurs through freezing and thawing cycles of concrete which may be 150 mm in diameter and 25 mm in depth or more.
