Concrete Contractors vs. Asphalt Contractors: Comparing Services

February 28, 2020

 

Blessed be the ties that bind. Therein is the key difference between concrete and asphalt: The binder.

Concrete and asphalt are both made with a mixture of aggregate. Concrete is bonded with a mixture of water and portland cement that creates a chemical reaction and hardens. Asphalt is bound with a black, sticky petroleum-based substance. This substance is behind terms like “blacktop” or “tarmac.”

Because of the key differences between the two products, concrete and asphalt contractors will offer different services to match the installation requirements.

Scaling

Preventing Scaling of Concrete Surfaces in Michigan

January 28, 2019

Scaling, as defined by the American Concrete Institute (ACI) Committee 116, is the “local flaking or peeling away of the near-surface portion of hardened concrete or mortar.” Sometimes called mortar flaking when it occurs just over the aggregates near the surface, it is primarily a physical action created by hydraulic pressures from repeated freeze-thaw cycles within the concrete. The expansive forces caused by the formation of ice are exacerbated with deicing chemicals, which increase both the saturation of the concrete and the number of freeze-thaw cycles. The distress mechanisms of scaling are complex on both a microscopic and macroscopic level.
